Short = early style, Long = late model... As for length I`m not sure but the difference is about 1 1/2 inches... Also the short pump fits tight up against the timing cover while the long pump has a gap of about 3/4 inch...

Others may have actual measurements...?

I believe the change was made about '68 or '69 when Chevy changed the alternator from the left to the right sides. I really don't think one functions better than the other.

Should have a long pump.If there enough clearance to fit a finger tip between the timing cover and the back of the pump its the long one.Most newer SBCs w/ the internal regulator alt on the passenger side use the long pump.
Short pumps are used when the alternator is on the drivers side like on older SBCs.They were also used on corvettes till like 1982 or something like that due to the radiator being tilted back.

Clock-wise or counter clock -wise?

Hi Guys,
Please allow me to jump in on this with a question. First of all, everything I've read here has been good info on the long and the short of it. However, I want to convert my '93 SBC from the snake belt to Vs.
So how do I ask for a long pump that rotates clock-wise and yet fits my engine? Do I look for a particular model / year? *************************** Thanks for your consideration. And 97Z28' thanks for allowing me to grab onto you thread.

Freedom is't free!
