When the motor was put in originaly, the guy who dropped it in had a lot of trouble with making what should have been the correct bracketry work for pulley alignment and fit. He took it upon himself to fabricate some stuff. While it all works (worked), its ugly as sin and NOW one of his brackets on the PS broke. I need to put the right brackets on this motor. With the amouth of torque it sheds, something else is bound to break.

The block is a late model ('99 i believe based on casting numbers) 350 block. The heads I'm not sure of the vintage, but they have 3 accessory holes on the front (see pics).

I've got the short water pump on it with a 2-groove pulley and a 3 groove crank pulley. The AC compresson has 2 grooves, as does the PS pulley and ALT pulley

The inner WP groove runs around the AC and crank
The second groove on the WP runs around the inner groove on the ALT, inner groove on the PS pump and around the crank.
The 3rd groove on the crank runs just on the outter groove on the PS pump

As you can see, the AC bracket bolts to the WP bolt and a second bracket bolts back to the head on the exhaust manifold bolts

The ALT is on a big arcing arm bolted to the WP bolt and a second sliding type bracket bolted to the manifold bolts

The PS pump has a managerie of bracketry bolted to the WP with a fabricated piece and the head/block. We had trouble with the PS pump before installation so he decided to find an original pump (instead of a nice chrome new one like he should of) and that may be the genesis of the problem.

I think either of these would be the RIGHT bracket for the PS pump I have right?

and either of these would be the right ALT bracket i think:

and for AC brackets:

Any of these look out of place to you? I need to find out which groove of each pulley the specific brackets run in so I know if they'll work. Anyone know off-hand and of these from experience?

I considered moving to a serpentine system, but just can't shell out that $.

Thanks all!

i just spoke to march. After looking at the summit PS bracket and reading more carefully, it says it will not fit A Bodies...so i called March. Thiers wont fit either. Don't think they clear the steering box.

Does this mean I need to go to a long water pump or change to a late model PS pump (type 2 I guess they are called right?)

Still trying to figure out what to do. I can't find a Ps bracket that will work AND that will work with a matching alternator bracket (drivers side). The March stuff doesn't sound like it'll work.

The closest I've gotten is a summit Bracket that didn't seem to be there a couple of weeks ago.

It's for SB, short pump, driver side, Saginaw pump... and made just for A bodies. Great right? Except it says it doesn't work with an alternator On the drivers side:

this one says interferes will most powersteering pumps

I think I read this one interferes as well

I can't afford to put a type II pump setup on and all that goes with that; and I can't afford to put an entire long ucterpump kit On....

Someone out there has to have a solution... no?

ok... I think I figured out what alt & AC brackets I need...

I have vortec heads based on acc hole measurements, and those look to be right...

in that picture, the Ps pump looks to stick way out and I don't think it would clear the steering box.

the Ps pump In this pic sits nice and tight though:

its the same part Number.

unless you HAVE to have the short water pump, why not just grab a complete front accessory drive setup off a 4.3 powered S10?
if a local boneyard wants too much $$$ for the setup, just comb the classifieds for a junker Blazer or something for $100 and grab all the stuff off that.
personally, i think the factory setups look much better than the aftermarket setups, and they are designed with million mile durability in mind, so you should never break anything.

i dont have to have the short pump anymore since removing the stock radiator and setup, BUT i have to have something a lot prettier than stock late model stuff. It's not now, I know, but I don't want to spend a bunch of money for a temp fix only to hate the way it looks and then have to spend more money on the sharp stuff. Id rather buy the brackets one at a time..but thanks very much for the info and suggestion
