Our L83 and L98 C4s have the standard coolant routing, as opposed to the LTx "reverse cooling", but our serpentine belt driven water pumps rotate in the opposite direction of the "V" driven water pumps.

If you want a stock replacement pump, I have a low-mileage take-off that I can sell you dirt-cheap.

Corvette have a short snout, reverse ROTATION waterpump. I went with a flow-kooler brand pump when I did mine. New pump dropped temps 10* over the old pump. Flowkooler is a higher volume pump than stock. Appeared to be a very nice pump, but it's only a water pump afterall.

Living in the ne part of the country, we do not have alot of hot summer weather. I use an airtex pump. It is a gm pump in the box with the casting number ground off. $50 instead of $200 from gm. Never a problem......yet

I put a flow kooler pump on my 88 about 6 years ago. No problems yet. I made the mistake of buying a cheapy for my 77. Lasted a year. Learned my lesson and only buy factory or high performance replacement parts.
