Hello, I watched the 454 chevy build. I want to build a 500 plus hp 454, and was wondering how much hp the 454 Camaro had. I know how to turn wrenches and have one successful small block build under my belt. I just don't know what heads, pistons, cams etc, I need.
The videos were awesome, and I plan to refer to them exclusively as I build my engine.
Thanks
Ed. PS, I want to run it on pump gas.

Hey thanks so much for watching the series!

Our big block is making right around that. What really makes power is compression. We are sitting at 9.5:1 I believe, so you could certainly go higher and make even more power on 91 octane. The limit for 91 is 11:1 or so just for reference. The other thing that you can do differently to make more power is get a hotter camshaft. I wanted something a little more streetable but there are so many way hotter camshaft that will make more power than the one I selected.

Hope that helps!

Thanks for using 2CarPros!

Best,
Ryan

P.S. Let me know how your build goes! I would like to see some photos!
