Loss is always an estimated percentage, not a set number. For example, a higher powered car might lose 40hp where a lower power car could lose 20hp.

IMHO that dynometer and your Yank 4500 stall are not compatible. There is no way your torque numbers should still be climbing after 5250 rpm. You might want to consider re-installing your old factory torque converter to tune with.

Just ran my 383 after a Frost tune on a Dynojet. Put down 471 RWHP/ 441 RWTQ.
All be it through an M6 and a MWC 9".

Remember the car has a th400 in it with a 4500 stall. Its not going to be a dyno queen but should run some solid numbers at the track. The dyno is a tuning tool to get the car tuned and let it rip at the track. Dyno's can be made to say anything but track numbers dont lie. This car should run some solid numbers.

Yeah, I can read!! My post was to simply put down some comparison numbers for the naysayer's out there not to emply anything else. As usual someone has to make a comment.

The car should/will run strong and be fun to drive...no doubt about it.

if the stock rockers don't fix the problem you might want to try a set of hollow stem LS3 intake valves . You can have them turned down as small as a 2.04 by TEA
