This is my setup. It is the underdrive setup for the corvette. I bought mine at Summit. I don't remember the exact part number right now but I will try and look it up for you.

Dude... Jegs just processed my order for $218 for:

V-Belt With Short Water Pump
655-5090 SB-Chevy, Drives W/Pump, Alt., P/S or A/C, Includes 3-Groove Crank, 2-Groove W/Pump and 1-Groove Alt. Pulley

okay i should have looked closer at this..

there are three sizes of small block pump.. short. long. and corvette.. you need to compare to your old pulley as soon as you get these

Ya... I jsut read about this. But the guy over at Jegs said that thats the only pulley system that they have from march taht fits a Corvette application

ok the pulley kit arrived today.
I am so confused its a 3 pulley set.

the description said this:
"SB-Chevy, Drives W/Pump, Alt., P/S or A/C, Includes 3-Groove Crank, 2-Groove W/Pump and 1-Groove Alt. Pulley "
ok minsu all the crap away and I thought htis was it:
3 groove crank - check I see it and verify it
2 groove water - check and see it
1-groove alternator check and see it but what I don't understand is this:
Alt., P/S or A/C, I never got an AC or Power steering! OMG! I already have an alternator pulley, it came with the alternator can't I jsut use that for my power steering, or AC?

Thanks guys,

If you look at my picture above what I got was a 2 groove crank, 2 groove water pump and an alternator pulley. Very expensive for what it is IMO. You can also see that mine is underdrive. It does come powder coated so there will never be any worries of polishing them to keep them looking good. Also be sure to tighten the pulley on the alternator pretty good or it will work its way loose and make a mess of a perfectly good pulley. I found out the hard way on this one. Put a flat washer under the lock nut. Mine did not come with a flat washer and the lock nut just ate into the pulley. Fortunately I found it before it did much damage.

will be sure to tighten them all down. However can anyone tell me if this is right:


1 Belt system.

However I already have that same alternator pulley tou have there Eddie. Is there any way I can use it for te AC, or Power Steering? This whay I don't mess myself over by having to buy 2 more pulleys?

Thanks guys,
-Louis

That is the proper position and routing.

Thanks Ken for confirming my thoughts. My big question is: Cna I use that pulley that was supposed to be for the alternator int he kit,a nd use it on the P/S, or the A/C?

THanks guys,
-Louis

Can you use that alt. pulley anywhere else?

No, the A/C pulley is part of the A/C clutch mechinism and the power steering pulley is a larger pulley that is pressed onto the shaft.
Your drawing seems to show the alt. belt going around the power steering pulley? It doesn't.
