Marcus, where did you get your power pipe and how much cutting did you have to do to get it to fit. Also, did your S351 come with the motor set-back about an inch. Mine did. The power pipe I have would take alot of cutting to get it to fit, but it is for a T or YS-trim vortech. I'm doing the winter engine upgrades and I'm thinking about adding a power pipe. I'd like to make 600 rwhp with the new combo. I went with a new rotating assembly (Billet steel crank stock stroke, 6.125 h-beam rods, and custom pistons. ). I have another built shortblock that will be for sale soon.
