I'm going to go way out there for a minute, has anyone one seen any documentation on how much air flow can be pushed thru the Olds 330 heads. I want to figure what are the MAX output numbers that this engine
safely handle such as- Cam lift, Engine RPM, Carb CFM, I know way tech for me but, I want to build/not blow up and keep my 330, and not go after a crate engine
Thanks always Brian

 

Need more information about what you want out of this. What’s the intention for the build? What gear ratio are you going to run? Did you want to stick larger valves in them? You can throw a cam that’ll throw a bunch of volume through the heads but you’ll lose low lift velocity.

 

Most kits have Option upgrades allow for substitutions at the cost indicated. Oversizes available at no extra cost. I.E. pistons, rings and bearings sizes

 

Try reading through this thread. It has gobs of info about flow rates and HP levels and more. It has info about rolling your own and even what to expect (to pay) from having work done. Hope it helps.
