OK folks here is the deal: We just took our 2 7's to a chassis dyno. The 04 car has a boneyard (80K mile) motor with all the bolt ons. The 05 has a 1 season old Speedsource motor.

The purpose was to see how much more the SS motor put to the pavement than the boneyard motor to see if we wanted to swap units. We only have one "right" diff and we need to optimize one car...

My question is simple: what HP numbers are ITS 13B's putting to the wheels? SS says if they build one for you with exhaust and fuel tweaks, then you should see 175 RWHP...

Anyone close to that? Should be no reason to keep this info close to the vest if you are legal, right???
