I did horse trading to get this car and with it came all the mod's. Got a dyno sheet on the car and it says 388 rwhp. I see alot of cars with less mods doing a **** load more HP. I dont feel the tune is that great. The car wont idle for **** in the mornings. Car still retains stock fuel pump and im wondering if the tune was held back for that reason. I have a 255lph to put in it, just not motivated to rear the ***-end of the car apart

What do ya'll feel this setup should put down?

Those gears and the stall converter are what are keeping the dyno numbers down. What does it run at the track, thats the realy to tell how powerful the car is. The same car with the same mods but in a manual with stock gearing may lay more HP down but not be able to run a quick down the track.

no track times right now. afraid to run it with the 10-bolt. though the more i read the more i see 10-bolts doing 9/10/11 sec passes so i might go out on a limb and run it if i cant ahold of some slicks

10 bolts usually hold up fine in autos
