I agree, dyno queens are for bragging rights for those that don't go to the track and would rather bench race.

Take the car to the track, and then see how it performs.

Take my car for example... a stock LQ9 truck motor with an EPS cam, dyno'd only 388 rwhp through a redneck racing 4,500 stall and a TH400.

Even taking it pretty easy at the track my 2+ ton car ran 12.0@111mph... using the Wallace Racing Calculator it shows the car is making closer to 415 or so to the tire.

yes,i do.the OEM airbox was designed to muffle the sound of air going into the TB,not to maximize airflow.you need to let that motor breathe!with the 243s and that cam,the engine is moving a lot more air.you took care of the exhaust,now your choke point is in the intake track.put a lid on there,and port your TB.those 2 mods should net you 15 hp,easily.
and don't focus on the dyno #s too much.every dyno reads different.the track is the real dyno.
