Twin 6265
Maybe or maybe not completely relevant to you, but a friend has the same turbos (6265, journal bearing, 0.68 A/R T4) on a 402 stroker, and he put down I believe 670 rwhp on a conservative Mustang dyno, while tuning "high boost" 14psi timing. So likely around 800-850hp at the crank. It also ran a 10.35 @ 135mph on drag radials babying it off the line with a 6spd, ~3600lb car with him in it.
I was going to say 800+ on a dynojet. A lot depends on things like locking the converter on the dyno, etc. I would expect a nice stock crank, cheap forged rod 370 deal to work just fine.

I think the newer PTE turbos would also maxed out at mid/high 7's, but he is likely dealing with the earlier version 62 or cast 62 due to the 65mm turbine wheel(non CEA) which is basically the same as turbonetics f1-65. On top of that he running a small .68 housing on a 6.0 which I would recommend for a fast responding manual car, but not a stalled auto.

This is the closest I can find for the turbo's I'm using. They don't make the 6265 anymore.
