Jon,
How are you coming along with the M1 install??? I decided to build up a
complete engine for my 98, with the M1. Head work is in process right now
and once the flow numbers are in, cam and piston selection/modification will
follow. The m1 is being port matched to the heads. Once the block and heads
are together, then I will figure out all of the details with the manifold. I
figured it would be an easier job with the engine out of the truck......
