I'm thinking more along the lines of porting the Vortec heads, a Comp XS274S
cam. Same flat top pistons with a smaller combustion chamber for a little
more compression. Weiand single plane with a 750 double pumper. Up grade
the connecting rods and swap the 4:11's for a 4.56 and spin it to 7200. Now
we are talking fun to drive.
