engine is a stock 100k plus mile 5.3 aluminum engine from a trailblazer

lingenfelter gt1-1 camshaft
comp valvesprings
holley sniper intake manifold
102 mm throttlebody
4 inch intake with no maf
hp tuners
electric water pump
no accessories other than alternator
th350 trans
8.8 rear end

car did really good.

All runs are done in 2nd gear. I think it would make a little more in 3rd gear. but with the current gear it turns over 170 in third. I am swapping a 3.73 in later this week and will put it back on the dyno after that.

best run was 386whp

Great results!
How come the Dyno started at 4000 rpm?

I have a 3500 stall torque convertor and it seems to be flashing a little high so i have just been starting the runs like that.

Wow. Stock ride height? What does the whole car look like? It looks like the engine sits pretty low in there and the hood is close-able. Do you have a build thread?
