best choice of supercharger for my 460 build?

getting a a460 block and will be stroking it out to prolly a 557ci... was wandering what choice would be best for serious hp looking not to be a op fuel car but a drag car with little street time just aorund the block and to nearest car show event...which would be best?

* procharger f1
*procharger f2
*paxton novi 2000
*671 blower with 2 holley dominators 1150 cfm or 1250 cfm
*no supercharger or blower and dual tunnel ram with 2 1150 cfms or 1250

f2 hands down !!!

Ok I'm not understanding the question that well?

DOes it say??? " *no supercharger or blower and dual tunnel ram with 2 1150 cfms or 1250"??

the line above that quote you asked about a 6-71?

Anyway if your going that size 557ci, a 671 is to small anyway.
You need to look at a 8-71 or a 10-71...

just put a 12/71 on it and be done with it

My list would be the following if I was in your shoes.

1. Procharger F3-117
2. Procharger F2R
3. 10-71

IMHO, I'd keep the bore a little smaller, say 4.440, to keep the walls thicker and hold the compression/combustion pressure. And, blown is right...a 6-71 is too small UNLESS you just want "the look".

a 10-71 should do the job nicely, 6-71 too small, 8-71 close but would heat the intake charge too much.

put turbos on and call it good

X 2 !

man put any of them on there and you be "A" ok...

Before you do anything you might want to see how much room you have in front of the engine. A Pro charger requires quite a bit of room as do Turbos. is the fuel cell up front already?

Be sure you havfe plenty of room if you go with a Pro charger or turbos.

If you decide on a roots, dont get anything smaller than a 10-71.

I'd also opt for an Aluminum case blower and not a magnesium. Also you might as well get the 120 degree rotors, Hi helix.

If this is a street car, Id do the tunnel ram and maybe some small shot of NOS. set up two carbs for street/race and then spray it at the track.

Roots blowers on GAs create alot of heat and are mainly for show. If you are on GAS take a hard look at a turbocharger. Unless you just want a centrifugal blower, a turbo is the same thing just more effecient, doesnt rob you with the belt.

It really depends on the type fuel you are going to run and what you are going to do with the car.

You can take advantage of some big power if you run alky mechanical injection with a blower but you can forget street.

For street /strip id look at some sort of Turbo/Gas/ EFI set up or the two carbs with NOS fogger.

JMHO

my friend is selling a f3r

holy necro batman!

+2 and only for looks, pick one of the others, and intercool it, if you want speed. Love the old GMC's but they only make power on methanol, they just heat the air too much, with their poor adiabatic efficiency

looking into a 500-525" build currently with a f2 blow through, want to do a-heads but might consider p51's depending on the $$

Either head will be fine. You can max the blower out with either.

 What will you do for fuel?  Do you have a carb?  Do you have a blower?  I have an F2r C&S combo here.  You would just need brackets.

planning stages currently, send me the info and pics on the f2 setup, want to do a mild 1000-1200 hp tune and have the ability to go to 1600 with a pulley change, while keeping it decently driveable, e85..

F2 or F3 if money is no object. Roots works good. Simpler. Mechanical injection for the track/dominators for the street. I'm switching to E-85 for ease of maintenance and cost. You'll have fun either way. Tunnel ram with a fogger would be way cheaper but not as cool or as fast. Still plenty fast.

Roots on Meth

was originally doing roots, just too damn big and obtrusive in a mach1, procharger will do everything a roots will do and make more power/fit under hood, thinking now of doing a big smallblock..

What did you decide? I looked into doing another SBF but decided to go BBF instead.
