I'm putting a 4.3 liter Chevy Vortec V-6 into my 26 T Tudor. I am using the short, "Monza" style pump. I ordered (from somebody, I don't remember who, it was quite a while ago) the supposedly correct Harmonic balancer and water pump pulley, for the short style SBC water pump, as I have been told numerous times that the Chevy 4.3 V-6 is nothing more than a small block with the back 2 cylinders slicked off... my problem is that when I put the pulleys on, the water pump pulley is too close to the block, by about the width of the bottom, harmonic balancer, pulley. I've tried shimming the pulley out from the flange on the water pump, but even that doesn't give me anywhere near perfect alignment.. anyone have any ideas?

your water pump pully is most likely wrong.

some pics would help alot

Thanks, Holder350, I'll try to get some photos tomorrow and post them up. When I look in all the usual suspects catalogs, ie, Speedway, Jeg's, Summit, etc, it appears as though you can get up to as many as 3 grooves on the pulley (I only need one) but there seems to be only "short pump" and "long pump" pulleys...
I was actually thinking about making up some about 1/4 inch spacers, that fit between the pump and the block, and just using gaskets on both ides of the spacers, and longer bolts, if all else fails...

like these?



I have never understood what these are for.

Thanks, I dreamed that little spacer up one night, staring at the pulley misalignment, and carshopinc.com now has my order for the .250" spacers, they are just what I needed.I had to check and make sure there wouldn't be any clearance problems between the fan and radiator, and I still have lotsa room...

Thanks again !!!
