11 seconds with a 416 - 11/02/09 11:37 PM
Any thoughts on how to build a 416 to hit 11's in a street car? Im planning on building one soon and was wondering if my combo would hit 11s or not. Going into a 73 cuda.

Depends on if your willing to run some gear and a stall converter. Then your going to need the right cam, compression etc. Really need to define what street means to you. Pick one of the builders that answer many questions here in the race section and you can't go wrong.
Ok now I see the four speed info. That makes thinks somewhat easier, except for traction maybe.

i am seeing them run ten-30-40's in race car trim.
i dont see why 11's in street trim wouldnt be more than possible.
cheapst.

LAR414 has one as well. Mid 11's will be no problem at all with the right parts. Jim

To me street means that the car is not all gutted for weight reduction, no slicks (although drag radials are acceptable). Im not in anyway considering running freeway gears, but at the same time nothing like 4.56s or anything that is too low for the street.

I've already told you the combo in my dart previously... Street car all the way... 11.24 @ 119 mph on Drag radials and thru the mufflers... 3350lbs race weight

My 69 Dart weighed 3500. It was tagged and insured. My times were on 9" slicks. 11.08 @ 120 mph. 11 teens and twenties in the heat were no problem. Ran a 4.30 gear with a 29.5" street tire. I could cruise 55 to 60 mph at 3200 rpms. I wouldn't want to take it vacation but for short cruises it was OK. Jim http://www.cxpressphotography.com/asccus...avParent=121400

KB forged step pistons 22.5 CC
Scat H-beams
Eddy heads ported by Ryan.. also shaved to obtain a chamber volume of 57cc.. which makes compression ratio 10.9:1
Heads flow about 280-ish cfm intake and 235-ish exhaust
Custom Ground Comp Cam 256/262 @ .050" Duration
108 LSA

Re: 11 seconds with a 416 - 11/03/09 10:32 AM
I ran a '65 Dart all summer with a very mild 416 on pump gas. Went 11.70 in the 1/4 but 7.37 in the 1/8th. Don't choke it off with crappy heads like we did. Ours were stock unported 360 heads with chevy valves, and it just lays down after the 1/8th mile. Changing them out for next year. Car was 9.5:1 compression on pump fully tagged and street driven. We run slicks for the track, but it 60ft hard enough it needs them. Car is just nasty fast till the 1/8th and should run low 11's early next season. The 416 is a torque monster that doesn't need a ton of gear to go really well.

No problem with a stroker. I drive my Cuda on the street...totally street able package (for me anyway). Even drive the wife and kids around with it.
360, Eagle 4 inch steel crank, Diamond pistons, Scat I-beams, ported eddy heads (Thanks RyanJ), air-gap, proform 750 dp, small solid roller cam, 8" converter, 4.10 gear, 10.8:1 compression on pump gas.
Still tuning, current best in sig, but I KNOW I will get this thing into the 10's next year (after swapping the intake and carb for a Victor and a 950).

I agree.. there is soemthing wrong with my combo, I think I should easily be in the 10's.. but thats for another post at another time..
In my defense, I still have air shocks and the wrong offset wheels which causes tire rub.. So before I can get serious cutting down the ET, I'll need to get better weight transfer.. until then, its a street car that I enjoy in this beautiful Calif weather..

I went 11.80`s years ago w/a iron headed 360+.030 daily driver and it definately was nothing special. Stock heads w/mild clean up solid isky cam, good valve job,10" vert, 3.91`s and loaded my drums up and drove everywhere for gigs up to 100 miles at times so today it should be a breeze as others have stated especially at 416 cubes.

Re: 11 seconds with a 416 - 11/03/09 05:55 PM
I've never been in the 12's with my stroker, since I built it like 7 years ago, at least never on a full run. The first time down the track was 11.85 and ran 11.07 last year with the automatic trans. First run with the stick and ran a 11.9 missing 3 gears and blowing the tires off.
Mine is very much a street car. No need to restate what I do with my car, and where I go with it.
These 4" arms are FUN!!!!

Homeade subframe connectors welded in place .I launch at 2500-2600 and shift at 5800.The car has a best of 11.48 in the 1/4 and 7.27 in the 1/8 and has more in it im sure.You can see in this vid how bad its spinning and costing ET off the line..11's should be easy for your 416 build in a street car...

no expert but you can do it with a whole lot less rpm and converter and the motor will live longer and be more fun on the street i gues

Re: 11 seconds with a 416 - 11/09/09 11:37 PM
Friend of mine and his brother both have 410 strokers both of fairly similar build.
360 blocks, .040 over, 4" cast cranks, eagle rods, JE reverse dome pistons, 11-1 compression, crane hydraulic roller cams, holley strip dominator intakes. 1 engine has the indy modified edelbrock heads and the other is out of the box indy heads.
The std edelbrock head engine is in a 67 Coronet, 3.55 gears, 727 auto, 3000 converter, full interior, battery still in engine compartment, car can be driven any where any time. Drives it to the track, leaves it in drive and on MT street radials it runs 11.70's.
Other car is a 64 Valiant, 904 trans, full cage, bench seat, mini tubbed, 3.91 gears, MT street radials, drives it to the track and has run 11.00 without really being tuned yet. They just switched it to 3.55 gears and have not run it again yet.

It only costs a few hundred bucks more to do the 4" crank stroker motor. And the crank is only about $100 more the grinding the 30 year old stock peice. I think it's crazy to not go the stroker route even though I have been 10.20s with a .040 standard stroke 360 at 3100lbs. Now it has run 9.68 at 136 and does this, with a stroker crank 360. Still home ported junkyard heads, 587 castings, .590 flat tappet cam, flat top pistons, and runs on gasoline, 110 octane.

Mines a 408 in a 69 Dart street/strip, 3300#. K-1 steel crank,Comp Star 6.125" H beam rods, Diamond 20 cc dish pistons, ported Edelbrocks, Victor 340, Bigs 950 HP, Hughes flat solid, 260/264 @ .050, .626/.633 lift with 1.6 rockers. With no tuning it ran 6.61 @ 102.24 (1/8) on the only pass I've got it to hook. The compression is only 10.9-1 so I run it on pump 93. It should run mid 10s when it's tuned.
My old hydraulic cammed, pump gas 340 in the same car ran 11.62.

I just figured that it would be cheaper to stroke it than to put even more parts into my 340 to maybe go just as fast. My goal is to atleast hit 11's but Im afraid my 340 will probably only be good for maybe low 13's(build posted earlier in topic). Plus with more cubic inches I have a lot more potential to go even faster.

Re: 11 seconds with a 416 - 11/13/09 05:23 AM
Probably not enough cam for what you want to do. You'll need at least another 10 degrees. And don't worry, these sb strokers make plenty of torque down low, even with a bigger cam.

Re: 11 seconds with a 416 - 11/13/09 09:46 PM
You can find something better than comp, there selection for mopar is not good and most of there cams have to much duration for a good street strip car.

A local guy has a Hughes 237/242 @ .050, .548/.555 hydraulic in his 408. It hits a good lick and runs 7 teens in a 3200# Dart Sport. IIRC the motor is about 9.8-1 on the compression.

Comp Cams has about 10,000 lobes they can grind on a SBM cam.
Just because they only list 30 in their catalog doesn't mean you
can't get what you need.

I have the comp 275hl in my 408. It sounds and drives pretty good. It definitely sounds cammed but isn't the rumpetiest, I can idle below 1000 rpm. Power comes on good in the midrange and pulls steady to 5-6k but no explosive cam 'turn on' in the upper rpms like a more radical cam.
I think I could have gone with the 285hl and gotten some more horses, but for a hot daily driver I am satisfied.

I did send it back and they did not take enough off, it took 2 weeks with shipping that i paid for so i had it done locally, they could not figure out way it did not fit, maybe it was for a chevy same grind.
