Just wondering if it would be worth it to go the 416 route with my 340 this winter. I am not happy with the current engine, and with the stock rebuild cast pistons that it has, I do not want to make too much more power and blow something up.

THIS CAR IS A DRIVER that I want to hit solid mid 12s (or better) with. I drive it about 30 miles a day to work and back, and regularly hop on the highway for 50+miles at a time.

Looking to build

10.0->10.5:1 -- with 59cc heads
240*@.050ish ---- .500ish cam
416cid kit
Ebrock Performer RPM heads 59cc with mild porting ------- HAVE
Performer RPM intake ------ HAVE

I have to get new pistons/rings anyways - in which case I would need all new bearings, too, so I was thinking of just getting a stroker kit from Mancini, and doing it all at once, and doing it right.

Is this overkill, or would I be better served buying new 340 pistons and a new cam?

What are some ETs I could expect from a 416 Abody (3400lbs)


Thanks guys.... gotta start planning this now.

You should be able to expect high to mid 11's from a decent combo. My friend has a 408 small block in a 67 coronet that weighs close to 3700 lbs with him in it, 727 trans, 3500 converter, 3.55 gears, drives it everywhere, has edelbrock heads, small roller in the mid 550 lift range, and will click off consistent 12.00's @ 114 mph. Go get the current issue of Car Craft, it is the white coronet in the mag.

No problem. The only thing is, put a smaller cam in for two reasons. One is that you are driving it everyday to work and such. The other is that you want a later closing intake valve with a 10 to 10.5 to one Aluminum head engine.

I would stay around 240 (maybe 245(max)) duration @ .050".

NO question go the stroker route. You can be a little more agressive with the cam than you would a 340 build up because of the cubes.

Also, concentrate on gettinig good flowing heads, whether it is ported stock ones, Eddy's or whatever. You want to shoot for around 230 cfm at .500 at the minimum.

Definately go with the stroker. I built mine a little more eggressive than your thinking but the nice thing about it is you will have all kinds of room to grow should you decide to later!!

you can get 12's out of a 340 with that compression and cam if you have some nice heads. 416 will bring you even faster so if you are just looking for 12's why bother with the stroker?


It's got a cop motor, a 440 cubic inch plant, it's got cop tires, cop suspensions, cop shocks. It's a model made before catalytic converters so it'll run good on regular gas.

with a stroker, you get streetability. peak HP potential is dictated by head potential. stroke will move the power peak up/down the rev range. do a stroker with your heads, good headers, and intake carb combo and a hughes 3038/3844ish sized cam (I'd use 1.6 rockers) and you're looking at something that should idle below 1000 RPM with 12+ inches of vacuum, and will peak out in power around 6500 rpm.

use the same combo with a stock stroke 340, you'll make about the same peak power, but it will be alot higher in the rev range without the low end torque, and it won't idle near as good, you'll need more gear/convertor.

Is it only the streetability that make the stroker worth building 340 and 360s will go in the 11s easily and be steetable those strokers are costing "per-the arcives 4500 to 8-9000 to build with the lower amounts to the guys who have machine shop skills or connections and the ability to assemble their own motors, from timeslips I have seen on this websight for some of the stroker cars mostly A bodys they are about the same as a lot of guys I know that run at LACR in california 3000 foot altitude also.One guy I know ran 11.40s-50s thru exhaust at 3000 feet drove it down 80 miles with 4.56s 8 in. converter and ripped off 11.16 at 122 thru the exhaust at a sealevel track
Motor -12-1 360 unported w2 econos 904 trans 456s and cam was an old crower split pattern 560 something and 263 at 050 and an 800 double pumper
Now I agree 12-1 can be a hassle on the wallet but thats what a lot of the buildups have also and the car is steetable for those that love this hobby but the car would be very competative with a lot of the stokers on this board and for a lot less money.If the stroker isa extremely steetyable than I would understand going that route but most of us dont have 7-8 grand for an engine.

I just dont think a stroker motor is the trick thing for ultimate ets and streetability or reliability, i know there are some stroker SBs out there that can run. When i go dragging i laugh my a$$ of at the bigblock A bodies that run mid 13s to low twelves . who sais thats more reliable or streetable to have your front tires caught in fender well headers or have your NEW starter burn out from you trick beat the hell out of custom chasis headers to run those ets. Or a 4" crank in a 340/360 ,ive seen lots more conventional motors run, as in the red 71 Duster in the mags that Greg Aliano has , ive seen that street driven car have a kill record that some people couldnt believe and carry the wheels on street ashplaht , with a 340 and mp .590 cam , so do you need a stroker for 12s no a stock 10 to 1 iron head 360 with a .500 to.560 cam and appropriate combo will suffice.

Crazy73 do you want an engine that starts to pull at 3000 rpm and not very good for power brakes around town, or an engine that has good vacuum and power off idle? Do you want a race car on the street, or a street car you can race? I have been deciding this for around a year, and stroker parts are currently being gathered
I have Eheads, RPM airgap, planning 230/236 @ .050 Comp XE 274 or similar, around .525 with 1.6 rockers.

Guarantee a 360 with 10 to 1 compression (true compression) with a set of J heads(202 160 valves) with JUST POLISHING the exhaust side,.484 purple cam,Performer RPm intake(I rather go with the stealth) 3310 out of the box holley, headers(1 5/8 or 1 3/4 dont really matter), 2800 stall with 391 gears, will set you in the 12.50s w/out a doubt, for sure NEXT

I guess I'm just jealous. I had a mid 12 car with a 340 (6 bbl, hooker super comps, 10.2 comp, 484 cam, 3000 converter and 4.30 gear). I am rebuilding it for more speed now and I wish i could go the stroker route but since this is gonna be low buck (donated pistons and crank) i gotta take what i can get.

i was just saying, that for mid 12's, a stroker is overkill.

BTW, my mid 12 was very streetable. It was my daily driver. sure the stroker may be MORE streetable but still my motor was plenty streetable to begin with.


It's got a cop motor, a 440 cubic inch plant, it's got cop tires, cop suspensions, cop shocks. It's a model made before catalytic converters so it'll run good on regular gas.

I built a high 12 second 340 street car for my wife and I can assure you that it is not nearly as streetable as the stroker of my friends. Not only that, her car weighs 3200 lbs and is a 12.90 player at best with 4.30 gears and his will crank off 12 flats at ease with 3.55 gears leaving it in drive and 500 lbs heavier.

The strokers arent all that much more expensive to build. It is all the additional stuff that people are doing at the same time that brings the price up. If you were to use stock j or x heads the only real additional cost would be the crank and a small amount of machine work. Otherwise, if you do rods and pistons and aluminum heads on either engine, the cost is a wash.

I have driven my friends car on several occasions and I can tell you that you will not believe how much torque the little storkers make and how flat the torque curve is. They will pull from idle to 6k and have you glued in the seat the whole time. I cant tell you how many big block guys have walked away from my friends car shaking thier heads in disgust after realizing the car is a small block.

Should also add that if you live in an area with emissions testing, the wifes 340 combo is a struggle to get through every year, but the stroker car flys through.

If you guys that think a stroker (equal build up) won't make more power and be more streetable than a 340/360, lay the crack pipe down, go recover for a day, and come back and read this post again!

Is a stroker necessary to run mid 12's? Nope, not at all. I had a 9:1 360, ported J heads, .549 cam, 4.56 w/30" tires, 3500 stall, pump gas, 3450 through the muffs running 11.7's.

Stroked it, with ported iron heads, same .549 cam, pump gas, ported 587's, same other set up but stroked, went 11.20@119. I only made 25 passes on it before someone from Dallas came down and bought it.

Both were as streetable as your Mama's grocery getter. I would drive the heck out of the car, even racing trailered cars (I had nitrous on it too) in which I followed them to the spot and had them unload...

If I had put a roller cam in it, got some time to tune it, easy 10.8's.

Here is a link to that build up: http://www.moparstyle.com/technical/stroked360.htm

I agree with comp....aar, I guess to me the .484 cam and 4.30's aren't what I consider "streetable".....3.55's max for a street car, as I consider a street car something I can drive on the freeway across the state.....

if you want a civilized, "mild" running car that can go that fast, a 408/416 is the way to go....if you want something that sounds meaner and you need lots o gearing and convertor that doesn't idle below 1200 rpm, then run a 340...
