Default Dyno numbers seem off
Set up is a 385ci stroker with ported lt4 heads and intake 58mm tb with 10.8 compression. The cam is a 236/242 @.50 550/570 lift with 114lsa. Auto with 3600 stall and 3.73 gears. Full exhaust and boltons and nitrous. On the dyno the car made 360 rwhp 460 rwtq on motor. Just wondering why the hp numbers are so low. Any help would be nice.

Thanks

I think with the Big stall you have, that could be a reason your dyno numbers are off as they are! Autos will not dyno like a stick car!
