I am still debating on if I want to upgrade the MAF (either 100mm or new housing-less) or go SD. I am currently still using the stock MAF so that along with the stock tb pretty much negates the 4" CAI tubing I have. Sounds like even though you have a few more cubes than I have, our motors flow about the same so get that fuel system in check so I will know how much boost a 3.25" pully makes.

I'm not sure yet. I know it will be more than 12 psi. I was making 12 psi with the 3.5 pulley on my 402 with long tube headers, 100mm MAF, Stage 2 Ported LS2 (car style) throttle body, and 4 inch induction piping. I can't go above about 4,000 rpm until I get my new fuel system installed.
What do you have right now on your truck?

It will be worth the wait. Pulley Boys got together with Innovators West to include their 8-rib crank pulley in the Pulley Boys kit, too. I know it will be cheaper as a package, too.
My truck is getting the finishing touches on the fuel system this weekend... then its time to start the 4L85E install

New fuel system has been installed... working out details now.
New peak boost from my 8-rib 3.25 pulley is 15 psi at a stupid rich 10 to 1 AFR. Once I lean that bit it may go a little higher.
3.25 pulley is good

Good to know! Once I get my tranny sorted out, I may jump straight from the 4" to the 3.25. Did you ever try the 3.25" pulley with the 6-rib setup? Just wondering how bad belt slip would be. Now with your 8-rib, is the IW crank pully 8" or the stock 7.5"?
How about some pics of the 8-rib setup!

I did not get to test slip because the fuel system was not ready yet at that point.
I do have the 8 inch IW crank pulley installed.
Pics will be available soon... the ones I took before were too big to post.
