Opinions on building a 12 sec daily driver cuda - 06/05/10 12:39 PM
After a failed 340 Im back to the drawing board with my 70 cuda. My goals for this car are to be able to knock down some 12 second times yet it still be mild enough to be a daily driver and also be able to cruise the interstate fine. I am open to either a big or small block. I definitely want an overdrive transmission to lower my rpm on the interstate. I have some of the stuff to put an a833 od transmission (iron case) in and would like to go that route if you all think it will hold up. When i can afford a 5/6 speed I will go that route. What I currently have for engines are a 360 block thats already bored and has 2.02 valve J heads. I have a 1969 383 truck engine that was rebuilt stock. Also I have a Late 70s 440 that needs rebuilt. So I can rebuild or mod any of these engines that you think would be best for my goals. So to sum it up... Im looking for recommendations on engine, if the 833 OD will work and gear ratio. Thanks!

I think the 440 would be the easiest build. You could achieve 12,s and still run a relatively mild hydraulic cam and dual plane intake to keep street manners. No replacement for displacement.

I have a 408 aluminum head small block. Its best is 12.74 at 108 with 3.23 rear gear auto. turns about 3000 rpm at 75 mph. I drive the car everywhere not the daily driver but will drive it 3 hrs to Atco or Engilshtown race and drive it home. I think most people would think it is on the edge of streetable. Fine for me

i would go with the 360, get a scat 4" stroker kit, have the heads checked with some bowl blend rpm manifold and a cam in the 226 to 230 2.050 range, it will weigh less than the 440 and you won't have to worry about wiring, mounts, and it will handle better. even a stock stroke 360 will get you hi 12's if done right

Stroke the 440 out to 493. With 9:1 compression and a set of Eddies it will make an easy 500 hp @ 5000rpm on regular gas without any daily driver compromises like big duration cams and hi stall converters or steep gears. You could likely run deep in the 12's with no more than a 3.23 gear and a Hemi type converter (2800 stall). My 4800 lb C-body ran 13.90's with a 2.76 and no traction with that combo. Subtract at least 1000lbs for an E-body and add some traction and you're there.

A mild 440 will do that with no problem. I can't see going to a stroker to just turn 12's. Find a good used 440 for a decent price, good exhaust, maybe cam, and 12s will be easy.

Re: Opinions on building a 12 sec daily driver cuda - 06/05/10 07:35 PM
The 440 will do it absolutely. What the stroker brings to the table is the ability to do it on regular gas with a mild cam that will get something resembling fuel economy as he wanted it to be a daily driver with freeway ability. For that application, displacement wins every time plus it leaves room to grow.

9.5:1 440 520's split duration cam w/ a 112 centerline, a little port work on 906/452 heads, headers, RPM intake and a holley 750DP, use a 2800-3000 tight converter and 3.73-3.91 gears and you'll be in the 12's easy. HOWEVER if the car is currently a SB set-up I'd stroke the 360, you might need more cam and some extra head work but w/ the OD you can still use 3.73's and be close.

how about a 360, use 273 rods, kb 10 to 1's, 508 hydraulic cam, adjustable rockers, windage tray, single plane intake, holley 750 with bigger jets and squirters. I had this in my 68 dart GTS with a 904, shiftkit, stock convertor, 3.91's. It would run 12.40's all day in 90+ degree heat. 32 degrees total timing. I had a full bodied car with full exhaust and street tires. Very simple to build, cost less than 2k in parts, and never lost 1 lb of oil pressure and I rode it very hard. It seen many 7k plus revs. Keep it simple and it will scream. Those stroker 408's are over rated and cost way to much for the power they make. Mine was well over 435 hp. Do the math. The best was 12.40 at 112mph. with zero traction and a 1.95 60 ft. time. With a stall and 4.30's and a small set of slicks it would have gone 11's all day.

I would prefer 360 if it can be done since I have more small block parts. But really either one is fine. Should the overdrive 4 speed be stout enough for either big or small block?

Re: Opinions on building a 12 sec daily driver cuda - 06/07/10 01:10 AM
It just kills me with alot of folks building these 408's and spending tons of money when they don't run any better than a properly built 360 at a lot less $$$. I'm not impressed with a 408 at all. If I wanted all those cubes I'd just go with a 440. I do like the 500's though. I like the idea of useing the lowdeck 400 block.

Go as big as you possibly can to begin with.
The 440 is the perfect platform to start from and with a VERY mild (read small cam, low compression) build it will go 12's with ease.
On the other hand, if handling will be considered go with the 360.

Re: Opinions on building a 12 sec daily driver cuda - 06/07/10 02:32 AM
A stock-stroke 440 will be able to turn easy 12s w/ no more than 3.55 gears. However, a small-block E-body will always handle better (more balanced overall) than a big-block version. I've owned both, so these are comments from first-hand experience. Figure out what's your priority and go from there.
EDIT: A stroker small-block could be the best of both worlds.

Re: Opinions on building a 12 sec daily driver cuda - 06/07/10 04:05 AM
The thing I like about a 406-408 SB vs 440 is less weight & easier to service. Also less fooling around with mounts, accessories, and possibly cooling. Pretty easy 12s, with enough torque that it doesn't need a bunch of gear. The 360 might be cheaper to build but will be a higher-strung setup for the same ET than a 406-408; but 12s are relatively easy. A 440 would require less modification for the same 12s. Either one would make a nice highway car, though the 406-408 will get better mileage, about 4-5MPG from my experience. The OD ratios are not an optimum "split" for drag racing, but building for torque would help there.
There's no wrong answer, really, depending on how you want it to drive on the street, but I really liked my 406 Duster street car a lot.

What happened to the 340? If you still have a good 340 block then just put a stroker crank in it and you should be good to go. Some Edelbrock heads (Magnum or LA) and normal cam, carb, intake upgrades and you should easily be in the 12's or faster.
A later model Magnum motor is also a good choice, especially with a stroker kit in it. The Magnum has some nice design features that the LA motors don't have.

remember the 340 with the 4.125 stroke crank is about 427" this is what i plan on a F.A.S.T. type Demon 340 build. but my hands will be tied with the stock intake and exhaust manifold probably only running high 11's. but then again i don't want to run a roll bar

Stroke the 360, eddy heads, 12’s….no problem…The best of both worlds, small block weight with big block torque.

Re: Opinions on building a 12 sec daily driver cuda - 06/07/10 07:44 PM
Over square stroking with over +4" limits the rpm for max torque production. Even with a hot setup. A 4.12 stroke will shift around well around 4500,4800rpm. The awesome part is that strokers do not need a lot of gearing, the longer crank throw advantages the torque, in a similar manner as the mechanical advantage gearing. 3.08-3.23 gears are fine. It fits a road car up for highway driving and enough torque to pull stumps out. Not to mention, you , rapidly through the gears. Carb choice progressive go AVS 800cfm, or standard QJet.
The 440 engine is your best choice cause you say it is there, and the engine with the most potential for EASY power. Big Bore and stroke in a heavy duty package.
The 360 can do great things if build with in reason. For highest performance road driveability, the most recomendable way is the complete Edelbrock RPM 360 mopar package heads/cam/intake/headers/3.91's. It may get you to the actual 12's, but not much fun at 65mph.

Man, if you have to stroke a big block to run 12's that's kinda sad. I mean, unless you are running like 2.74 gears or something, but still....
Is gas mileage a consideration? You did say DAILY driver but I'm ASSuming that it won't really be driven every day.
Posted By: Twostick
Re: Opinions on building a 12 sec daily driver cuda - 06/08/10 12:48 PM
Then it wouldn't really be a daily driver would it?
It's not that any of the suggested combos can't run the #, you could build a 273 that would run the #. You just wouldn't want to drive it every day if ever and cruising on the freeway at 5500 rpm would get old pretty fast. For what he is looking for you want big cubes low CR and a small cam. He posted that he would like to keep it 360 so I would suggest a turbo could be in his future.

Re: Opinions on building a 12 sec daily driver cuda - 06/08/10 04:34 PM
Big cubes, mild CR and mild cam. A stock stroke 440 will give you great street manners while putting you well into the 12's. If you did something like a 10:1 440 with edelbrock rpm/440source heads, edelbrock rpm or holley street dominator intake, headers, 800-850cfm carb and a mild hydraulic cam like a lunati voodoo 60303 you will be deep into the 12's and can run 11's if you ever change it up to a more aggressive cam.

Re: Opinions on building a 12 sec daily driver cuda - 06/08/10 07:27 PM
I'd do an RHS headed 408 small block, brian at IMM has a package he built up in the race section that was pretty tame and budget friendly (~$5k complete), but made enough horse to push his duster into the 10's.
maybe cam it down a bit (had a comp XE295HL, IIRC, maybe drop to a 285 or 275HL) so you don't have part throttle surge at cruise), and run 3.55's with the OD, or 2.94's with a low gear 904 and 12's shouldn't be a problem.
or start with a magnum block and stroke to 408, and run a roller cam

I agree,my mostly stock 360(except for cam and heads) runs mid to low 12's easy.
gears and vehicle weight have a lot to do with it.

true, but 4.30's, 3500 RPM converters, 240-250@.050 cams aren't exactly street friendly....
another option if you want a daily driver that runs in the 12's? get a 300 SRT8 (:

Yes a factory high stall convertor. Was someday going to switch to a 3400 but sold the car before. The car is on utube doing a big burnout in Heath during the nats a few years ago. Do a search with kenworthgoose and you'll see it.

I didn't know it would take so many cubes to make a mild 12 second cuda. How difficult is it to swap a 302 or 350 in? I know some cars running those engines that are well into the 12s and are mild enough to be driven daily.

A ford or gm motor 
I hope your joking! All you need is a mild 440... there people that have take later 70s one, add steel shim headgaskets, good cam, converter, and some gears and run 12s. They are low compression and you could run 87 octane for street use. You don't need a stroker to run 12s, it may make it easier, less gear and converter, but I cann't see spending the extra money. Some of the combos here better run deep into the 11s or 10s for me to even consider spending the coin to build them!

well, a street driven cuda with all the comforts, etc, will probably be in the 3400-3600 lb range, which takes some power.
it's easy to do with a simple stock displacement motor, if you're willing to take some compromises in gearing, drivability, and fuel economy. the 302/350 cars you mention probably have the same compromises. the OD tranny's gearing is kind of wide, so you need to take that into account when designing your motor. you need to make the torque curve flaaaat and wiiide. smaller displacement motors to make the power tend to be peaky. Ad in a high stall lockup torque converter, and you can get around the peaky torque curve.
IMHO, the key to making the power is good heads. the better they flow, the less duration you need in the cam. less duration makes the motor milder, helping with drivabulity and part throttle economy. wider LSA's also do that. if you build a 360 and a 408 identical (same cam, heads, intake, compression, etc), they will make the same horse power, but the 408 will do it at a lower RPM, and also make ~12% more torque, and have a more tame idle.
for me, If you wanted to start with a stock stroke 360, I'd start with a 360 magnum. Then I'd add some edelbrock or RHS heads, slightly massaged, and KB107 pistons. I'd then run as agressive of a hydraulic roller cam as I could, to maximize .050 and .2" duration while minimizing seat duration and overlap. I'd also run a modded edelbrock LD340, and run a demonsizzler prepped big block thermoquad.

A VERY mild 440 will run 12s on pump gas and be extremely reliable.
Here's a mild combo that I drove 3 hours one way on the interstate to college, yet ran 11.80s at the track.
440 w/ Ross flattops, stock bottom end other than the pistons.
906 heads w/ a 3 angle valve job, that's it.
9.8:1 compression, 93 pump gas.
509/292 purpleshaft hyd. cam, stock rockers and pushrods, 0933 hemi springs
Edelbrock Performer RPM intake, 830 holley DP
1 7/8" headers, 3" exhaust to the factory tips w/ flowmasters
727, 10" 3500 stall, 3.91 gears
Car weighed 3700# w/ me in it.
ran 11.80s at 112 mph. 7.50s in the 1/8.

Re: Opinions on building a 12 sec daily driver cuda - 06/09/10 07:51 PM
without an overdrive, anything lower than a 2.94 for the rear isn't daily driver friendly, especially if you go on the interstate at all.....
with an overdrive and 26-28" tires, a 3.55-3.91 is about the max....
and a MP 509 doesn't sound very DD friendly either..
224-230@.050 is about the max I'd consider for daily driver cam duration for a motor in the 340-440 cid range...

I gave my combo as an example of how good a mild combo can run. Take some gear, cam, and converter out of it and you'll still likely have a 12 sec car.

Rebuild your smogger 440. Run a cam in the 224-228 duration range, wider LSA (112 or 114) and split duration, headers, aftermarket intake, hemi stall, 3.55s. If you shave the heads and make sure you have a true 9.5:1 compression ratio I think you'd hit high 12s for sure. If the budget allows use a six pack set up, but those are easy to toss on later.
Spend a little bit of time opening up the bowls on the heads. I think this would be the cheapest and most reliable way to go in the long run. Stroker LA engines are cool and can make some serious power, but with a 4+ inch crank (and a really short piston to use it) I don't see how those things can last nearly as long as the 440. A big block is a tougher engine to start with as well, but they're all made well.

This car is driven to the track, raced in 2 classes so it is hot lapped, runs on pump gas and its not a stroker, just a 340 full interior steel wheels change the tires at the track to a small slick, 1.60 sixty foot with slant 6 suspension,
runs 11.90s all day!

given your current parts, if you're not willing to start out with buying a magnum 360 core motor, I'd use the 360 block, stock crank, rods with good bolts, KB107's, RHS heads from brian at IMM, and a lunati voodoo 60403 cam. I'd be tempted to go with the magnum style heads to run cheaper (small block chev style) 1.6 ratio rockers. for rockers I'd probably look at Scorpions. intake, either redrill the heads to LA pattern, or run the magnum air gap.
if you're running 26-27" tires, I'd go with 3.55's and the A833OD. has a deep 3.09 first gear to get off the line, and should cruise at 70 mph in the 2400-2500 RPM range.

stock 360 - small valves and an eddy tunnel ram
3.23 gears and a 904 with low gearset
16 mpg on the highway
12.56 best et
108 best mph
i think alot of recipes listed better be in the 11's or somethings wrong with the build!
I agree,my mostly stock 360(except for cam and heads) runs mid to low 12's easy.
gears and vehicle weight have a lot to do with it.
true, but 4.30's, 3500 RPM converters, [Email]240-250@.050[/Email] cams aren't exactly street friendly....
another option if you want a daily driver that runs in the 12's? get a 300 SRT8 (:
the iron case A833OD should live if you don't hook hard...
mine has 3:73's and a 2400 converter,it is very streetable and can be driven anywhere anytime.
