Correct. If you replace these flat belt pulleys with conventional V-belt pulleys, the system works just like any other multi-belt system. This is NOT a serpentine belt, it's simply a flat, multi-rib belt. This was used on lots of engines in the 80s. My 86 Chevy truck with 454 (with two - count 'em - A.I.R. pumps) uses a similar mix of four (!?!) belts, one flat multi-rib and three conventional V-belts. On the other hand, my 99 Chevy truck with 454 uses a single true serpentine belt (and reverse rotation pump) to run all the accessories.

below is how my TBI 5.7 V8 in my 87 suburban is, but I bought a 3 month old GM crate engine that was in a 90 chevy p/u that lost the drie shaft and broke a new 700R4 tranny around the bellhousing (daddy told his boy after a engine swap & 700R4 tranny swap to sell it, and he would buy the boy a new ex cab 4x4 p/u). I bought the complete 5.7 TBI engine with everything, a 1 belt serpentine belt system, water pump, fan, TBI, PS pump, A/C pump, just everything for $800. I'm going to put this 1 belt serpentine belt system on my 400SBC with a/c in my 74 Camaro. its a reverse rotation standard flow water pump with this 1 belt serpentine belt system. did I say that right ?


some info I found
[/i]ON OLDER MOTORS YOU HAVE TO TAP AND PLUG A SMALL HOLE ON THE PASSANGER SIDE OF THE WATER PUMP PORT THE NEWER WATER PUMP DOES NOT USE OR COVER THAT HOLE you can see in the picture what the style of the front of a motor this came off [/i]





thanks

It had a serpentine belt going around the crank, water pump and alternator, and a v-belt for power steering. There was no tensioner, and it used the old-style alternator bracket to get the belt tight, and the regular water pump.

Here's some pictures of a pair of pulleys I have lying around that I think are the ones I'm talking about.
