F-2 blower to big for a 408?
F-2 if I were to go ahead and run the F-2 would I have to run a cog system or is an 8rib up to the challenge?
My goal is to break 900whp what I have is a 408 with a CR of 9.6 cometic head gaskets studded all the way around with Callies rods and crank Diamond pistons and the crank is keyed, but my heads are stock 6.0
Any info would be great thanks everyone

A f2 will most likely take less power to spin at that level and make the same hp. It is a much larger unit, and will take a custom bracket. I would not even try a 8rib with this, you will get carried away and crank that boost up

A custom 12rib or cog would be the best best, we all know a f2 is not a daily driver unit.

Aint that the truth. I have never personally seen a f2 with a 8rib setup so i would not know. But a bigger wheel and different impeller pitch would make things alot worse for belt traction with a 8rib. how much are the 12 rib crank pulleys for the ATI balancers? do you have any in stock?
