−	I'd also go w/the 455. You will want to go with the "large" round port heads though. (Ram Air 4's are the best,Ram Air 5's w/high comp.pistons,or HO's.) I'm impressed with the horsepower & ease of streetability in the large Ponchos. They bolt right in however, most driver's side headers need slight modifications. There's limited space (using such large primaries) & 455's are one of the few powerplants that require little backpressure.{in high peformance aplications} Remember: those 67's are extremely heavy for a midsize Gm body. The added cubes come in handy. You'll also want to stick with the 400 turbo.	+
