Smaller power steering pulley?
Looks like I won't need a smaller pulley. I forgot the s&p motor mounts put the engine further up, so the belt isn't lined up with the bolt.
The A arm is fairly close but I will need to get an alignment once I'm all done. Hopefully they remove 1 or 2 of the alignment spacers.

Today I bought the Doorman 300-301 pulley and tried it. Didn't work for me with the Vette accessories. It fit on the pump shaft, but wouldn't line up with the other pulleys.
Ordered the CTS pulley yesterday, should be at the dealership in a few days. I wondered about the smaller pulley effect on the pump too. Obviously it will spin it faster, I was told the pump is internally regulated so pressure & flow is the same.
A friend of mine told me that the truck pulley is 5.5 OD, but I haven't been able to find the ID of the center hole. The Trailblazer one I have, the ID is .75, won't work on the Vette pump.

Samckitt,
I wish I was listening to you earlier. You are correct that the Dorman 300-301 pulley does NOT line up with the c5 corvette accessories. I had a squeak issue that I have been chasing for six months that all leads back to this pulley.
here is what the correct one should look like...

and the dorman one

Old thread, I know, but I was wondering what the diameter of the stock LS1 F-body p/s pulley was. I don't have one physically in front of me to compare to my current setup and am wondering if it would be worth the ~$40 to get one.
I'm going to add to this as I am in need of a 5" pulley and really don't want to buy a billet dirty dingo unless that's my last resort.
I have the corvette pump and holley bracket, my pump shaft is the .66 version. I found a thread where gary68 used a dorman 300-201 but his bracket looked like a truck bracket and dorman's website shows the shaft dia hole to be around .75 or something, def not .66
Any suggestions??

Check out the Dorman 300-126 if 5 3/4" will work.

After doing some measuring , even that much less on the pulley, it's going to hit the hi-pressure pump fitting on the gearbox
I broke down and ordered the dirty dingo 5" pulley, Thats going to give me plenty of room I need. Hated to spend that kind of cash on a pulley and they charge $14.50 shipping for priority mail in a small flat rate box which is only around $5 so that was hard to swallow lol.
But I needed it and had no choice

Hi Folks Im in the UK suffering with this LS Pulley problem, I have a 48 Chevy Stepside Running a Corvette LS1,My PS Pulley began spinning on the shaft. I ordered a Corvette Pulley and was told it didn't fir possibly because Camaro/Firebird LS1 have different shaft sizes, The Corvette Pulley purchased was too small. Ive since learnt that not all Corvettes have the same shaft size some .66 some .72, I take it mine is a .72. I had the fibre Pulley boss machined to fit but now suffer belt squeal and Im told that the pitches are different on some pulleys.....Id like to buy a Metal Pulley and Im told again that aftermarket pulleys are $100+ and yet an LS2 is $20 and upgraded to metal, Does anyone know the shaft size on the LS2? or are they different too......Im gonna hopefully stop the squeal today using a Gator Belt......

where is Dino's corvettes salvage in the UK or USA? Handy to know. I think I have the squeal problem solved the belt fitted by a Corvette Mechanic here in the uk was not only old but it was the wrong size and the tentioner was actually bottoming out. I purchased a new belt locally and fitted it myself now the problem is solved. However if the LS2 Meatl pulley fits Id like to replace the fibre pulley just fitted as I do not trust them.......
