New Numbers
I'm alittle surprised it's only hitting low 500's with your setup and 10lbs.Timing set low for the juice?Compression too low?
We have a 9,5-1 402 doing 569rwhp with the 4.0 pulley -4lbs of boost. Just put on a 3.4" pulley and will be dynoing it tomorrow

CR is 9.0 with 18*-20* of timing. Once I get the AFR leaned out a bit, I will play with the timing some more.

I would be happy with those numbers.
I don't think a half point on CR would make that much of a difference.
The only other thing is the heads. They were Absolute Heads and we know he went out of business.
And I do lock the converter on the dyno.

BTW-3 of my 346's push more HP than this 402 with smaller heads and Cam,so cubes don't make that much of a difference
