This is a brand new small block Chevy 305, 350 and 400 belt drive and pulley kit. For use with short style water pumps with up to a 5/8" shaft.

Kit Contents:

  • Billet aluminum water pump pulley
  • Billet aluminum crankshaft pulley
  • Chrome steel alternator pulley
  • Cogged belt

The cogged 1 1/2" wide "Gilmer" style belt prevents slippage. Water pump and crank pulleys are a 1:1 ratio. Must be used with the factory alternator position, alternator pulley has outside lips to help keep belt aligned. Will not work with A/C equipped vehicles. Works with mechanical water pumps only (will not work with electric water pumps). Some applications may require a spacer for the crankshaft pulley.

I've wasted a lot of time, water pump gaskets and oil changing balancers and both short and long water pumps. Seems to be the closest with a long water pump and the thicker of the 2 sbc balancers. Anyone have a link to the 1/2inch crank pulley spacer they used? About ready to just throw these away and forget about it. Also need a shorter belt as the one it came with is way to big even with the adjustable alternator bracket maxed out.

Nice product! The belt length in the listing would have been helpful. I had to order a longer belt for my application.
