Default Radiator/water pump?

A guy told me that LS1 water pumps were reverse-flow just like LT1's, but I didn't think they were - which one is it?

Also, will I be able to keep the motor cool with the stock 69 Camaro SB radiator and electric fans, or do I have to buy a new radiator? If so, any suggestions?

yes your radiator will be fine. A stock 4.3 radiator is keeping my 6.0 cool.

Reverse flow cooling isn't part of the water pump, it's part of the engine design. LT1's were reverse flow cooled meaning that water went thru the cylinder heads first and then the block.

LS1's are not reverse flow cooled.
