i sprayed a 250 shot direct port in my 93 lt1 stock bottom end it only took 2 races to break my rod in half and crumble my piston to pieces. i did this cause i was gonna build the hell out of it anyways now is it possible to build this for a 250 shot or should i still lower the shot it is a direct port kit..i want to build it the faster the better but when im done i dont want toblow it again...
any help please
thanks

 

Depends what you mean by "build this"... I've sprayed 300 on top of a 500HP NA 381.

-Pro-Gram 4-bolt conversion
-Callies Stealth crank
-Oliver 5.85" billet rods
-BME forged "nitrous" pistons.

Dry system, not direct port.
