F1-R on 6.0L?
I am going to build a 6.0L with 317 heads and cam, 1-3/4" headers. Will an F1-R be too big or will it work ok until i get a 408? Would F-1A or F1-C be a lot better blower over F1-R? I heard it may be more peaky power/boost. As long as the blower is RR will it fit both fbodys and vettes???
This car will be both street/strip.
Thanks!

Yeah they are the same rotation head units. You will sacrifice quite a bit of low end if it is a street car. For a track only I would hit up an F series head unit. But that is just one opinion and well I am sure there are others that will disagree with me, but i am just judging by what the car is doing with the F1 and 346 right now etc...

I couldnt afford a new motor this year how i wanted it built, so i am getting a used 6.0L with cam.
So eventually I will have a fully built 4xxci with good heads. So i want to get my procharger setup for the future installed.
I realize its probably a little large for the current build, but just want to make sure its not going to suck compared to a F1-A or F1-C.
Maybe peaky power will help for a launch?
I drive my car quite a bit in the summer and race it as well.
For now I will probably run 9-11lbs and make 5xxrwhp on e85.
My guestimates

I ran a F1C on a 6 liter just fine heck i got a few pulleys for you if you need them to spin it a little slower. When i spun it slower i still had 10 psi at 6k rpms and about 2 psi at 2k
The F1R I think will be better for a track car. They flow a little more up top but takes a little longer to build boost. They like to slip the belt a little more to which sucks if you going to street it.

The way I see it, it you have a 408 or smaller displacement with 4 bolt per cylinder heads, and you don't live at 6000 ft, the F-1R is not necessary and would only take more horsepower away from the engine to turn it. An F-1A on a 408 can make you 19 or so psi, the F-1C would make 21-22 psi or so. The dyno graph below is from an LS2/402,EPP blower cam, off the shelf AFR 225 heads and a ProCharger F-1A. Yes, we could of made this boost with a D-1SC, but we would of been working it much harder, which can create higher inlet air temps. Bob
