What camshaft spec for 425 hp

Don't forget. You're gonna need to get your driveshaft length altered.

Thank you, I had a driveshaft built for it with 727 trans.

Ooooh, bummer....Just FYI, switching to the 727 from a 904 will slow the car down some (1-3 tenths of a second from what I understand). Not saying that you can't go fast with a 727...heck, that is what I use, and my car boogies, but when you start looking for every last bit of ET you can squeeze out of a combo (if you are into that sort of thing) you will be wishing you stayed with the 904.

My 904 let go and my friends trans shop had a built 727 and made me a deal that was hard to refuse. I know the 904 trans most likely be best for quicker et, but sometimes money talks.
