A member over on V6Power.net just ran an 11.3 with a stock shortblock motor, CNC heads and other mods but the bottom end was stock, it was a 4.2 truck bottom end though. His pump could not keep up and he detonated and blew the motor at the end of the track but she holds up fine, he has put her through many dyno runs at well over 400 RWHP on the stock shortblock, it was the lack of FP that klilled his motor just the other day. These stock motors can handle quite a bit, he ran like 486RWHP I believe on his last dyno run, Powerdyne blower with a 25 Dry shot of nitrous gave him the extra power, without the dry shot he made like 442 RWHP I think.

 

it must run real good

 

Amazing numbers!
