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

http://www.ryanscarpage.50megs.com/combos1.html

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
