A stupid question for my 10,000th post on cz28!!! What is being referred to as "long" or "short" wrt both SBC and BBC water pumps?

Thanks.

Rich

 

The length of the impeller shaft. Most sbc's before 1969 used the short version.

 

Thanks. What about BB?

I thought the corvette got the shorter one......the sides where the 2 bolts are is short its smaller than the other one. And the long one has kind of a snout to it where the pulley is, the short one is really close

 

thats what i thought too, i ordered vette pump a long time ago cause it was alluminum and i wanted to see if it would fit on my third gen

 

That makes more sense than the impeller, but I don't know - that's why I am asking???

Why are you asking? b/c I know the brackets for alt. and the crank pulley and stuff are harder to find but depending on what your doing it may not matter.

 

Enquiring minds want to know*

oh...well the pulley is different too just so you know, I ran into this before and could never get the right stuff so I just got a different water pump to get it all lined up right.
