I'm running a 103.5 and it works with pulley sizes 3.25, 3 and 2.75.

 

Ya sorry guys, 6 rib is holding up. Ran into a few problems so I was unable to go to the track this past weekend but I am up and running again. Possibly next weekend if the track is open

 

As far as mods go the bracket build wasn't too bad. I think a guy sometime makes things harder by overthinking it. I like PRO TOUR HOE's idea as well.

 

heres is a pic of my btom hole and rocked the racket I mounted the truck bracket with the bottom bolt and pivited it out just far enough to clear the throttle body which is flipped over so it clears the shaft then i drilled and tapped the aluminum plate and bolted it up . basically I moved the bol hole in the head over about an inch and a half

 

***BUMP*** for an update on this set up, like to hear where things are at, thanks!

 

I like your solution for moving the alternator. Pretty simple really. Do you happen to have a CAD file for the bracket?

 

What do you guys think of the bracket made by Dirty Dingo? It retains truck alignment and accessories. $219.

 

Dirty Dingo Builds some really cool **** I am running their motor mounts my mount is really simple and looks pretty stock .Its just a 1/2 inch aluminum plate big enough to cover all 3 bolts in the head I had a buddy machine 1/2 inch oss the back of the alt mount in the area where the mount meets the plate put the bottom bolt in the mount down by the pwr steering pump and rock out until it clears the TB use a centering punch where you need to drill the holes to reposition the mount then drill and tap and your all set and you saved 200 bucks
if you need more pics I can get you some
