Need to know if anyone has done a D1 procharger with a 408 motor?
Hoping that the procharger is good enough for the 408 motor cuz if not so i can build a 370 with a D1 procharger

F1 Procharger? Im sure it would work. But may be like putting the magie 112 on a 6.0L. Could max out pretty quick.

What are your goals? What are the engine specs?

well to say i blew up my 5.3L in the truck now and im thinking of getting a 408 built for boost and try and do it in like a month or two. Want to get close to 700-800 horsepower and still gonna have to build a trans and rear end plus drive shaft. Just want to see what the motor will get when i install it in the truck.

if you want them numbers just go turbo, but with that 408 you can hit that goa easyl chit i hit mid 700s in a 6.2 376ci

I have a 390, which is pretty much a 408 with a shorter stroke (3.825 instead of a 4) and have a d1, really wishin i had a f1a instead. Dont get me wrong the d1 is fun but ya you'll want more, and a d1 will be tapped out at 800

I ran a D1 on a 408 for a while and made 700+rwhp. It was maxed out and I was having to overspin it to keep the power up on the top end, terribly inefficient and not good for the blower, an F1D or A is better suited.

Thanks I was worried about that but I guess it's back to the drawing board. Probably sell the pro charger and buy a turbo kit.
