Default reverse flow radiator???
In installing my 1994 LT1 in the 68 Vette, are there special reverse flow radiators that have to be used? Or can a stock type radiator be used?

Thats a good Question. I have a 96 GS but its not near by to see. The water will flow threw the radiator fine I'm just thinking about the Bubbles getting traped. Th one time I drained my LT4 I had a lot of trouble bleeding Air out. They have two bleeder screws to aid in the process but it still took a wile.

I don't know that which radiator matters...as long as it is sized correctly. But the engine was designed to have the heads cooled first, so a "reverse" pump is probably required.

The LT1 already has a reverse flow water pump, which is why I ask if a special radiator needs to be used.

To repeat: If the radiator is sized appropriately, no.

I agree, It won't matter which way it flows through the rad, and the stock rad is likely big enough for your average LT1 but I can't say for sure

IMO, you would want the water to flow through the radiator in the same general direction - top to bottom. Left to right doesn't matter.
