Can I install a long water pump on my vette? 1978 Corvette

Not if you plan on having any belts on it. The pulleys will not line up and then you would have to try to find a pulley that would work....and if you try to extend out your crankshaft pulley....you may have an issue with the cradle now getting in the way....and forget about doing anything with the power steering pump pulley.

Honestly I do not see a reason to change it to a longer one...but you did not add anymore to your post but a basic question....so it is all guess work.

You can bolt it to the engine but nothing will work that attaches to the front of the engine....ALL Corvettes whether BB or SB engines use the short pump....period.....

Just make sure the short pump will not jamb against the face of the timing cover.....there should be a small gap between the two covers when the new pump is bolted in place

Short pumps come in two different lengths/hard to notice/ from the back cover of the pump to the engine block depending on the year----I think....the correct pump will bolt on without having to add extra gaskets.

You can, anything can be done but I think the question is why, and what would it accomplish when completed, compared to the original set up ? All brackets and pulleys would need to be changed.

I did on my 1980... a long, reverse flow waterpump... along with a F-body serpentine conversion, and electric fans.

The long watepump is not a direct bolt-up as others have said.

To be precise the water pump for a 71-82 small block Corvette is neither short or long;

Short Chevy Pump = 5/8" pilot diameter & 5-5/8" block to hub distance

Long Chevy Pump = 5/8" pilot diameter & 6-15/16" block to hub distance

Corvette Pump = 3/4" pilot diameter & 5-13/16" block to hub distance
