pulley

[ms93gt]

Hey guys I'm new so I'll start off my introducing myself. My name is Mike. My car is a 93 gt. I'm building a 306 and it has a new crank, reconditioned rods, new speed pro forged pistons, anderson b-31 cam, twisted wedge heads, track heat intake, accufab 75mm t/b, all supporting fuel mods, and a novi 1000. I wanna put the 8" crank pulley on with a power pipe but was wondering if they make a bigger than stock sized blower pulley, something like 3.75" or 4"? The reason I have the 8" is because I read it brings the boost on quicker but I don't wanna run 10-12lbs only because I know thats gonna put my car into the 500rwhp range and I don't wanna crack my block. I'm looking for around 430-450, as long as it runs 10's with full suspension. Any suggestions?

I think ASP does custom pulleys, but Im pretty sure the old SN paxton came with a 3.75 or 4. It was huge.
