It was just the dyno is was on. that dyno reads really low. I going to be taking it to the track and drynojet soon. prob will see 540 to the tire on the jet. i know for a fact the numbers are low because my old h/c/i motor on the jet was 435/398 and i have tons more power with the stroker. I cant make any guesses on numbers without really seeing them but i shoulds be around 540/510rw. And the motor only had about 50 miles on it when dynoed. Have you had yours out to the track yet???

I agree with others you won't see 540 on a DJ.. 510 was a good guess maybe 520 on a good day.

For reference. I made 499rwhp on a Mustang dyno on my 402. I backed that up with 535rwhp uncorrected ona dynojet. That would be around 520rwhp corrected on the dynojet.
I think you'd be lucky to see 500rwhp.

I made 540/420 RWHP/tq on a mustang dyno with my high comp, high rpm 366, by your logic I would make ~620 on a dynojet? Thats absurd. I think you will pick up some, but not anywhere near what you think.
