Having a bit of trouble with my non a/c alt. swap

Oldsmoletick-i've noticed on your engine pic of the olds,you're running the alternator and p/s pump on the same side,my question to you is,doesnt the water pump bearings squeal like hell?I've had both my cutlass supreme and cutlass salon squeal like a pig with that setup causing me to put the a/c compressor back on.

I am not sure if this is what he has, but there is a set up that people seem to have good luck with. You need to get a 2 groove power steering pulley and the crank and water pump pulleys from a 350. Use the 307 alt. bracket and 307 a/c water pump.

It doesn't squeal, but it is a little tricky to get both belts to have proper tension on them. I have been running this set up for almost 9 years now, haven't taken out a water pump yet :shock:, but I did put a new pump (stock) while installing the engine, maybe that's why.

The whole "offset load" thing is a myth. Think about it. Even with three belts, the load is straight down towards the crank. The bearings in the water pump are symmetric, so they don't care about the direction. In engineering this is called a vector sum. Each belt imparts a side load to the pump in some direction. They don't cancel out, they sum to a resultant load that is still a side load as far as the pump is concerned.
