Default Block Hugger headers on LT1

They won't fit without some modifications. They contact the motor mount and the knock sensor slightly.

well that's not gonna work, a pipe nipple and a 90 degree elbow can probably allow you to rotate the knock sensor outta the way; not so sure about the motor mount; I'd definitely wrap it in some heat reflective material, ala the factory.

What make are those headers? were they corvette / year specific?

Those are procomp headers for a c3 I had on the shelf. Wanted to see if they would fit.

close; next, a pair of solid motor mounts and you're on your way

I think the other style might work well. Will find out when they get here in a few days:
