Interesting, so how do ya go bout changin firing order? Sounds complicated. Can it be done thru stock PCM using HPT or say, EFI? Or is a FAST or similiar $$$ setup needed?



Now, that's what I thought too.

Flow matched injectors flow close to the same, but they may be one that puts outa hair more fuel then the others.

Not sure about the crossover tube my heads are stock and have never been removed, but i don't remember seeing any back there when i did my trans swap

The pistons I'm getting are wiesco 5.3s there not the coated ones with the smaller ring..... They should be able to handle more heat right? Has anyone burned up a number 7 forged piston?
