looks like combo 13 on ryan's small block dyno website.

It made 430hp at 5000 rpm and 435 ftlb at 3800 rpms. Also says the data was from the ARF website so it may be on the high side.

i think the 430/435 estimate from the website is a bit high

i would guess around 400-410hp and 415-420tq (not a bad little street motor)

now if you were willing to go with a hyd roller cam set up with a similar duration but yet closer to .550", and spend a little extra money on having those heads cleaned up just a little bit, i think those numbers could be closer to 440hp/440tq
