Should just put a Chevy in, a lot cheaper & easier.  |
Everything as light as possible. With a 2.20" titanium intake valve, titanium retainers, light weight lifters, and the right lobe I turn 7500 rpm with 155/410 springs. That's not to say an FE will turn that with the same parts, as Brent said, the FE stuff will be heavier.
Edit: The LS7 also has light weight and strong rocker arms which helps too.
