Jamming in a big block?

I'm having the same debate.
Exhaust is the biggest problem, depending on your skill set might not be that big of a problem.

Not a fan of the 408 design a 383/400/440 with are better engine designs especially when using the 440 crank in the B engine (cheap stroker). And if I was gonna spend 408 stroker money I'd rather have 500 plus cid. And with the new trick flow heads it's hard to want anything less than a big block.

But if under 550 hp a 408 is not the worst choice.
