There's a recently rebuilt 400 with ported and polished 6X heads up for grabs for cheap. I'd like to know if it is a direct bolt it? I'm pretty sure it is, but just wanted to be certain before I pull the trigger. It is complete from edelbrock intake to pan + chrome headers. From what I have seen, It is a steal at $550.
WHat do you guys think? Will I see big difference between my 350 and the 400?
