Thread: how much tork and hp do i have

Tweet

i have a 84 S10 with a 355 small block w/a 272 powermax crane cam 216-228 dur w454-480 lift was wondering also what rpm's should i shift at? if anyone else used this cam let me know it has 981 comp and has world prod sr ported and has 373's gears w350 turbo full manul vaule body 2800-3200 tci it pulls very hard and i like it can't wait to run 1/4 mile. yee haw

i will go out on a limb with what info was given and guess a rough, 325 to 350 horses. more info will get a better idea like, intake type - duel or single plain, and brand, carb size and type, valve train type, piston type - stock or flat top or?? its hard to throw a realistic number out there without as much info as possible. also shift it at 5500 to 5700 with info supplied.

it has forged flat top pistons w 4 valve on top of the pistons and the intake is a holley Z-28 it's a duel plane w/a 700 double pumper turn down to a 678 cfm mated to the cam and gears. GM distribter with a high performance 50 thousands voilt coil and w/ the right stuff inside. thanks for letting me know stock push rods and 5.7 stock rods w/ arp bolts it has roads lifters and crane roller tip rockers 1.5 the block has been balanced and blue printed and honed and tork plated 0 decked on the block. Arp bolts all thou the motor it's a two bolt main and the crank turned down 10 thousand and polished i hope that helps. thanx again mooneye777

alright thats a better list to pop into the desk top dyno. these read a bit high in my opinion, but they are a good source for comparing parts against each other. your little mouse belts out 402 horses @ 5800 rpm, and 398 flbs torque @ 4700 rpm. you listed no valve size, i went with 2.02x 1.94, in my opinion a single plain intake would be a better choice, it comes in at , 419 horse @ 6000 rpm and 400 flbs torque @ 5000 rpm. about a 17 horse gain. and also your 2 bolt mains will serve you well as long as you do not over wind it. keep your shifts at 5700 and no higher and it will take a good pounding.

their 194'- 150

i have read last night in a book same cam as mine and pretty much everything else and they said almost what u came up with that's wild i think it's good for 13 in the 1/4 what do u think?

do u have a hotrod? are u a chevy guy? just wondering i was thinking of changing intake i'll keep that in mind of what u said single plane can u recamend a good one. u have been very cool giveing me at least an idea what i have in my motor i also have cal traction bar's going on it sometime i have to send u a picture of my S10 sometime.

I would have to say your carb. might be to big.
I would say all you need is a 600 vac.
I would guess in the 325 area for hp.
