yes that is my thinking on this. this would be the only big block i have not stroke i think i must be working backwards then i can say i got it covered to 4.750 stroke

modified dome from speed pro

hey super jim , 454 crank? in a 396? im lost here what else did you use? like carb and other parts? i dont really look intoi the stroke on the cranks , know what i mean? like i will undertsand it more in more general terms, any way, whats in your 396? how strong is it?

10-5 compression merlin oval heads 750 speed demon rpm air gap intake 1 1 3-4 headers crane roller cam 610 632 lift
428 ci
416 hp 500o rpm 467 torque 4000 rpm
over 400 lbs of torque from 2000 to 5000 rpm
that rwhp it runs mid 11s in a 3500 pound chevelle with driver

so guys its sounds like it would be a better bet and more power if i bored out a 396, figuring that they are harder to find and so are the parts, i was reading a tech article in chevi hi performance, it was pretty cool. i think thats the way i will go, sounds like a better bet, also hey guys, how is the throtle response on these engines? cuz i was looking for something not to touchy, like i dont want a engine that will haull ass if i barely touch the pedal, you guys get my drift? how do these engines respond? or does it depend on your set up?

some of the old 396 you can bore out to 4.250 bore but not many .i had one back in the day this you be a 427 and then with a 454 crank it would be a 454 ?? but why? get a454 block and put 4 1/4 crank in it then you have a 489 0.30 over or 496 0.60 over they make a lot of TQ. my old 396 did not have much a268 comp cam good valve job and some head work bowl and a single plane holley with a thremoQ carb i would dump the clutch at 6500 it did run very good for not alot this was in my gto in 1980

i found a eagle competition rotating assembly on summit, forged kit, would this be a good kit to use? how far could i push it with this set up?

for what engine i can,t say much good about eagle but do what you want

what? i cant understand what your trying to say, the kit is for the 396, and can i use this kit to get the numbers i want?

what numbers ??and the eagle cranks are not that hot . but like i said do want you want. i have seen them and talk to my crank grinder and they are way off. but i build engines and check every thing. and there stuff dos not hold to my standards. but like i said do what you want. any one can make a kit for 396 i can build a kit you. just need to buy the parts that fit

okay but i want an enigne that will haull ass, like i said, im looking for a combo that will get me around 450 hp and a ton of torque, through the 396's you have biuld what combos work for you? thats what i want, what have you used, what parts? tell me what you have done to your engines to get these numbers.

real simple one stock gm crank one set of stock rods with arp bolts. one set of pistons what heads do you have ? small roller cam what do you want soild or hyd you have said you want this to run on pump gas right ???tell what heads you have and if you want a soild roller hyd and we can go on

i dont have a block yet, i want low compression, what you recomend for a cam, hyd, or roller? and what kind of heads would you use? and what carb, i want a holley, what else do you use?

you can not have every thing. it will be hard. like i told you the cam could be a hyd roller or a soild rolller i think a small hyd roller . but i want you to think for one minute . you want the same that a ZZ502-502 makes with your 396? you do not have the cr and no cid ? to do what you want .you will need some cid like i said. and a good set of heads there are many sets of gm heads ? and like i told you cant get many pistons for this so? if i tell you use 781 heads and run 10-1 were are you going to get the pistons? they would have to be custom at $900 or the 500 trw may work and the roller cam the piston will have to be fly cut intake air gap or team g carb 750 and good set of headers and ex

Hey Mad Hooker, why don't you check out Scoggin-Dickey Chevrolet??? {sdpc2000.com}.... They have crate motors that are right where you want to be HP & TQ wise. Such as a 450 HP 502 that puts out 450 HP & 550 FT LBS. {8:75 to 1 compression}. Price; $5788 & change. This is everything except the carb, ignition, & exhaust. If money is tight then purchace the short block & then get the rest later. Or if money is even tighter yet purchace the bare block, then the crank, pistons, rods, heads, etc. later on..... They also have a 454 that puts out 440 HP & 500 FT LBS. The 454 block is $600 bucks cheaper to start. This is what I might have to do for my project. These are PROVEN combo's. You'll know what HP & TQ to expect going into the deal & it'll probably be cheaper also. Brand NEW, made in the USA parts ...... Hope this helps ya, Bill

502 - 396 = 106, which is 106 + Ft. Lb's more........

ps, & it'll look like a 396. Only you & this web site will know! And I for one won't tell..... ;0
