Those specs look close to the torque 2 EPS cam. I am with the others I dont think that dyno is accurate. I talked to Geoff and he recommended about the same size cam for a dual purpose fun/tow vehicle so I wouldnt expect that high of numbers from a cam like that.

Derek just put down 455 with his 6.0, which is way nice for a 6.0. So I wouldn't say 60 less hp for a 5.3 is too much of a stretch. In fact, cube for cube, Derek's numbers are higher. Its not too unbelievable.

For the record, I ran him when I had my twincharger setup with the stock 80e converter, and we were about even til I pulled away at 90ish mph. The truck is quick, I can personally vouch for that.

Those are pretty sweet times for a NA 5.3 and such tall gears. IIRC, those truck thruster converters have a pretty high STR, so I'm betting your gears just eat that up. Pretty slick combo if you ask me
