Default Water pump

What is the recommended water pump?

Sleeved 5.3L, dressed out to replace the LS3 in a 2010 base Vette. 427, maybe 10PSI boost from a CSC.

Thanks!

The OEM Corvette pump is not too bad. Edlebrock makes a good pump with the outlet on the drivers side like your Corvette. The Edlebrock water pump also has a very wide water pump pulley for belts which is good for you blower guys. The key with the Corvette is a good fan set up. Dewitts now has a dual 11-inch brushless fan system that flows 30-40% more than the old brushed system. Draws 40+ amps compared to the old 30 amp brushed system.

Radiator is biggest part of the cooling equation. Put the biggest/baddest you can fit.

When the SC was added the thing was to use a short radiator. I have heard (but not seen) a full sized radiator can be fit under the A&A tube from the aftercooler to the TB.

The new dual 11 inch brushless fans from Dewitts might work also. Being only 11 inch you could put them on the lower side of the radiator - not sure how tall your core is.
