i currently have a 393 that i just installed in a 94gt and im wondering if someone can give me some tips on the problems im gonna have with the computer......the new 393 has all new fuel injection ..jus wondering about how to set the computer up for a 351

 

the stock computer isn't gonna be able to compensate for a 393 it has a hard enough time compensating for a big cam. you might want to check in to a aftermarket computer for your car.

 

So the firing order on the factory 5.0HO is gonna be the same as the new 393 ..but the computer is really gonna lag...i wonder if it will start at all like that...so what u are saying is a new computer or jus a mod chip
