What are the differences of each? I see the 598, 598AB, 420, 772 ect.. I know some are low deck and some are for standard decks, but beside that? Are they all equal? I know the 420 is the big player in power but are there better choices for different applications?

I use the 420 that I milled to fit a 1050 dom... I
havent looked at the other but I would assume the plenum
size is different as well as the deck heights

772 is for a tall deck. I have one but it was mistakenly milled wrong and when it got corrected guess what. It now fits a short deck block.

I also have a 598 and a 420. The 420 is the baddest of them all as you can make it much larger inside.

Thanks guys. So were some designed for nascar and others for drag racing? The overall design looks to be the same.

"420" was dragrace only as NASCRAP did not like the way the "420" looked so it was never run in the trucks. "598" and "598AB" was the nascar intake.

I took those pictures on Kent's table at the Indy show.

I haven't started on Jeff's 420 yet.

Brett probably has some ported 420 pictures?

Heres a pic of one of the first 598s that was rough
cast that I machined to fit a 4500 and doing the port
work... its done now but I still havent run it yet
to make sure of the port balance using EGTs
