well, I'm done. The whole shebang...

IronMike, As my signature eludes to, mine are W2s, ported and built by Brian at IMM. The motor is all by IMM, too. I think that Carter pump is holding you back over 6000 some too. I switched from that to a Magnafuel 275, with line size increases too, and noticed much better throttle response over 6500. This is on the street. The car didn't feel like it ran out of gas anymore, and pulled much harder to 7K.
All of my dyno runs at IMM are with an electric fuel pump, never with the mechanical.

My gross lift is .698 too. Compression is close to yours also.
