Thread: how much tork and hp do i have

Tweet

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?

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.
