Your gonna have to turn a 318 8000-10000 rpms to make 625-725 hp (that's a huge gap in hp) heads are gonna be in the 350-400 cfm range which is gonna be bigger than 2.02 valves. I can't see to many stock parts surviving these requirements.
Brodix B1BA Heads, does anyone know the exact bolt spacing for 318/340 main caps? I need to make some billet main caps. The only stock parts I'll be using are the block, timing cover, and maybe the crank. I'm looking to get the crank magnafluxed this week to see if it's any good, I'd like to get the journals welded so I can machine a radius into them.
