I am looking for estimate on what kind of power the car will
Make, it's a 2002 lm7 5.3 in a 74 corvette with a TH400 the
Heads are 862 with 2.00" intake valves bowl cut and blended with tick street heat 2 cam 60lb deatschwerks injectors and MS3Pro stand alone ecm. Headers are 1-3/4" stainless through 3" exhaust with x pipe and chambered mufflers. Truck intake with k&n filter. That's all I can think of right now. Also the engine was rebuilt with new bearings,rings and so on and arp rod bolts. It also has a nitrous outlet wet plate. Thanks gents

Pretty big cam for a street 5.3, do you have a higher RPM stall converter in the th400?

I'd say it should make ~320-330rwhp on a dynojet.

OEF14vette

Yes it has a 3600 rpm 10" convertor. But I think it's flashing closer to 3900-4000 rpm... i am racing the car so we were trying to make it max effort for what it is... do you think the corvette IRS will soak up some power

the th400 and the rear will eat up some, should run well though

Okay thanks, I will post some dyno number soon.

My guess is that it won't break 300...

My truck made 260 rwhp with nothing but a 205/210 drop in cam and a tune on a stingy dynojet (all cam/bolt on or head/cam/bolt on LS cars I've seen on it are right at 25-30rwhp low and blown ZL1 and GT500s were lower than that).

I've seen bigger cam 4.8 trucks with headers crack 300 on a more lenient dynojet.

I guess 340 rwhp

Your very close madmike had it on the dyno yesterday and it was very surprising what it made.. I am not giving up any numbers right now since some fellow competition is on here and we start racing the 21st But to say the least it makes 2 HP per cube on nitrous at the tire.... thanks guys for everyone that replied.
