Hi Guys. I have a few questions for this group. I am putting a 305, L03 out of a 91 Camaro, into a 1953 Chevy. My first question is, is the water pump a short or long pump, and if it is long do you know if I can get a short one for it? Secondly, is the pump reverse rotation on that engine?

Thanks in advance, Johnnie

As it came from the factory, it's a long water pump and is reverse (CCW) rotation.

If you order one by application ('91 Camaro) you should be OK with what ever pump they hand (or mail) to you, provided you keep the same belt drive system that came on the Camaro.

Thanks so much for the response. That's what I was afraid of. As I said, I'm putting it in a 1953 Chevy with v belt not serpentine. I need a short pump for clearance. I guess I need to find out what years of pumps will fit.

Thanks again.

Keep in mind that reverse rotation doesn't necessarily mean reverse FLOW. All the short pumps that I know of are standard (clockwise) rotation, so you will just have to try one and see if it bolts up. If it does, then you will need a short pump balancer and an early LH exhaust manifold to mount the alternator on, and of course short pump pulleys. Also, you MIGHT need to swap the timing cover (or at least the timing tab if you can weld it) if your present tab doesn't work with the short pump balancer. When you go looking for parts, I believe passenger cars changed about 1969 and trucks and Corvettes a few years later.

If I missed anything, hopefully someone else will chime in.
