Swap in a set of Trick Flow heads and watch the dyno #'s wake up.
I think the top end is the culprit. It's not breathing.

thats a huge cash outlay and kills his objective of keeping it mostly stock looking.
Some IndyX heads would be the best thing for this. Lol, ive got a new set prepped by IMM. Will trade for trick flows!!! Haha.
