If you go with an engine over 400 hp, you had better go with polyurethane motor mounts and scrap the pos rubber sheet that comes with the roller. Eric at PE knows exactly what to use. The reason being your engine will torque and the side pipe will hit the bottom of the passenger side opening when it torques.

As far as engines, nothing smaller than a 427 displacment, either stroked small block or big block. The difference is a stroked small block is like fake breast, the size and perfect shape is there where the big blocks float on their own but sure sag quicker. Either way they both get the job done.
