Acessory drive?

[w3bb3r04]

What the heck is the acessory size for a stock vortech. 4.5 or 6? I'm getting a new 8 rib setup. 6.85 crank and 3.12 compressor size. I just need to know the acessory size. If anyone knows help me out lol

It's either. All depends if you want an underdrive for the accessories or you want it like having a stock crank pulley.

Which would you suggest?

Depends on your setup really. Have a stock alt still or a 3g? The underdrive (4.5)will spin all the accessories slower which is a problem for some cars with a stock alt and things like a big stereo system or electric fan.
If you have a big 3g alt with a small pulley you can get away with the underdrive (4.5) without problems and gain a few hp...if its a stock alt I'd stick with the 6" std drive.
