Has anyone ever gone from a 3.25 to a 3.00 pulley?
 
What gains dod you see going from a 3 1/4 to a 3 inch pulley on an E-Force?

I made 474 rwhp and 434 rwtq with an eforce 3.5 pulley, kooks, and detroit rocker cams on the stock bottom end. I never dyno'ed her with the 3.25. The 3.25 made me too nervous so I didn't run it very long.
I would not even chance the 3.0 pulley with the stock rods.

Not really a comparison - I do not have a stock bottom end anymore (plus I added 45 cid & ported FRPP Stage 1 heads) but I picked up around 100 rwhp & 150 rwtq using a 2.75 pulley (and still on the edelbrock 41lb inj).

I picked up a 3 inch pulley for $30. Just wondering how much it would Add over what i have now which is a 3.25

A 3.0 pulley would probably add 20-25 rwhp

I must admit if you are who I'm thinking of you are making over 500rwhp on the stock bottom end, I am surprised you haven't popped it.

Those are some impressive numbers (538 RWHP/498 RWTQ).. what dyno was that done on?

Did you make a thread about your B326 block installation? Could you link to it? I've been eyeing that block for a while now.

I initially didn't make a thread about the installation because I took the car out to Brenspeed and had them swap in the Long Block. I will start one.

Heres the link to the B326 thread:
