Turn a small drill press into a Bore/ Hone. Bolt it to the top of your engine block & do your own machining .

I got a question also, I found this Holly Strip Dominator intake manifold with, what looks like a piece of PVC block off cap cut and installed on the floor...should I keep it there? More HP maybe?

Personally I think I would remove it because it looks like some of that may be coming loose. And if it does come loose it's going to hit that intake valve and hit the top of the piston in the combustion chamber and then try to go out the exhaust valve. But that's just me I would rather see a block of aluminum welded in to the manifold personally. Jmho
