Been a little while, figured id post some updates. The stock motor never gave up with the 66mm on 34-35psi, she just kept on going. Hit a personal best of 166mph at mpact, wanted a 1/4 et pb, but ended up with a mph best of 146mph. Good enough i suppose lol.

Fast forward, got rid of the small bw 66mm and went with a pulsar 7170g, as well as built motor. Built 8 bolt, css, stock comp manley pistons, manley rods, arp hardware, ported head, ferrea valvetrain with shrick high lift cams.

Still on first revision, but cold = no traction.

That thing is moving :D
How much boost and timing is this?

How much torque did you apply to the ARP headstuds during assembly? Did you also do some heat cycles and retorqued the studs again?
