What do you guys think?

Hes going to get the Mickey thompson street radial and He has also lowered the gap to .45. The 13psi was in Park. He now has 8-9psi in gear with a 4.5 PV and I will tell him to junk the spacer and adding to all this he does have and adjustable snubber.

And I think he said in the future he might either port the magnums, or go with the RHS 360x magnum head and possibly go to the eddy intake and port the intake to match the heads.
