I just picked up this car about a week ago and before I go and get it dyno'd I was wondering how much HP i should expect, this way I know if there is a problem or not.
Here is a list of whats been done to it. I realize that not all things listed increase power, but I just copy and pasted it from the ad.


LT4 CONVERSION,BLOCK BORED .30 OVER, FORGED SPEED PRO PISTONS, MOLLY RINGS, LT4 CAM AND TIMING CHAIN, .230 EXAUST CRANK RETURNED RODS, .010 UNDER MAINS, .020 UNDER RODS, BALANCED AND BLOCK STRESS RELIEVED, HOT TANKED PUSHRODS (6MM), EDELBROCK HEADERS, HYPERTECH PROGRAMMER, LT4 INTAKE MANIFOLD, ACCEL MULTI SPARK IGNITION, MAGNACORE PLUG WIRES WITH NGK IRIDUM PLUGS, AEROMOTIVE AJUSTABLE FUEL PSI REGULATOR, POLISHED TRICK FLO AIR INTAKE ELBOW, CHECKED FOR LINE BORE, CENTERFORCE STAGE 2 CLUTCH, NEW POLYURATHANE BUSHINGS, FLOWMASTER 40 SERIES EXAUST, HIGHFLO CAT, THICKER FRONT SWAY BAR, 4:10 RICHMOND GEARS, 160 THERMOSTAT, PANHARD ROD

 

I will say this much if u have all that done to ur car the hypertech is worthless at this point,cause the computer would have to b reprogramed by softwere and the hypertech doesnt cut it, if the comp has not been reprogramed for the lt4 upgrade u will need to have it done to gain the most of what u have, so i would look into that when u have the dyno done c about a dyno tune and sell the hypertech cause it is only any good on stock motors.. as for hp i would take a guess maybe around 325 330 thats just a guess of what u have up... and welcome to camaro forums....

 

yeah if its the complete LT4 conversion with exhaust mods on it you should be running maybe around 350 HP and 340-350 ft/lbs torque. thats just a rough estimate but i know that a full LT4 conversion puts you at 330HP and 330TQ so the exhaust will boost you some off of that

 

i really have no clue, but man you pretty much have my dream set up, either that or a supercharger
