Just to confuse you even more I have a long type pump fitted.:thumb:

Same on my 383 - long style fitted Watch out with the short versions that you have enough space far the alternator.

So far as rotation is concerned:

Clockwise if you are using ordinary V belts and pulleys (where the v belt runs around the outside and over the top of the water pump pulley)

Anti-clockwise if you are using a flat "serpentine" drive belt.


Sooo.... the one you gave a url for from Summit is the wrong rotation for the pulley set you indicate.

You definately need a long fitted, I had a short fitted when I bought the engine and there's no way (without a load of hassle) that you can fit the alternator with the standard brackets. :thumb:
