[jc70chevy]

i have a 355 bored 30 over procomp aluminum heads 64cc solid roller cam 575 lift 110 lobe seperation and 1.6 roller rockers 13/4 headers and victor intake holley 750 dp what do you guess guess horsepower to be ????? anyone????:here!:sorry compression it 10.5 to 1

[eville]

425

[josh@scotts]

depending on your how much comp, and if you have a good cam ,airflow, ihave to agree ,425

[jc70chevy]

10.5 to 1compression

[josh@scotts]

thats a good compression with an aluminum head, depending on cam duration @.050 man thats gonna rev, ive seen 545 from that same setup depending on cfm of heads

425 seems very conservative. As Josh said, depending on head flow, you should see over 500 easy, especially with a 780-800 cfm carb.

[jc70chevy]

im not for sure but i have the flow chart for the heads but i want to say 230 but i dont remember i just no it it hauls

Probably a safe 450; 500+ on a 358 usually takes 280cfm+ cfm heads, bigger roller, lightweight pistons, etc. (I had 530hp out of my prev. 358 with the same compression and an older set of modified tour 23 degree heads and .634 lift)

[josh@scotts]

yeah i bet your problably taken up to at lest 7200!

[josh@scotts]

68, motown block huh nice!!

[68sixspeed]

yeah i bet your problably taken up to at lest 7200!

the 358 made peak hp at 7000; but the torque was still good, 450ft-lbs at 5400; the 427 makes peak at 6700-6800 and a good 557ft lbs at 5400. (the 358 is for sale!)
