Well wouldn't it be cheaper to go a machine shop and ask them to do all of that for me then install the lumps and stuff myself?

Also, what type of HP/TQ do you guys think a blowthough 500cfm holley 2bbl will make using the off and 2.5" 3-stud log manifold @ 6psi on the stock longblock?

EDIT: I also got outbid on that ebay 500cfm holley 2bbl. What price range do those things usually go for?

EDIT 2: Also, when I weld the pipe to the mounting flange for the turbo, should I try to fab the pipe into the square shape for better flow or should I just weld the pipe straight on and using thick sheet metal to cover what's left open? the 2.5" pipe almost dirrectly fits from top to bottom and it leaves some space on the sides which I could cut and weld pieces into.

69 Buick Special Deluxe. Intercooled Turbo Chevy 250 @ 15psi on a stock long block. It's kinda fast.
