BBC build for my 72 chevelle....

[Youngblood]

I would like to get at least almost 600hp out of it. Do anyone knows what to do and what parts you think would reach that point?

Here's a list of things i thought would do it but i'm no way sure.

Comp gold 1.7 rockers
Comp mutha thumpr hydraulic roller cam
Comp hydraulic roller lifters
Comp pushrods for the hydraulic roller cam
Port and polish the heads. (don't know if i have much room to shave them because of the piston height.)looks like 13.8cc. dome he said he could only use 91+ I guess that would be around 10.23:1 ratio
I already have Edelbrock rpm air gap for the oval heads
Speed demon 850 carb
