Im curious of what intake runner size you have on your heads, and the lunati part number for your cam?
I've got a very similar built motor in my 260z and i will say it really get up and goes and i can't even use its full potential because of some clutch issues i have, having a th350 being built right now actually
My motor is a 383 11.3:1 AFR195 237/242@.050 .605/613 lunati solid roller QFT750 and RPM air gap, but may switch to a Victor Jr.
