Need measurement, Engine to radiator w/long H2O pump - The 1947 - Present Chevrolet & GMC Truck Message Board Network

BubbaGreen · 02-06-2005, 05:12 PM

Can some one please tell me the clearance from the front pin sticking out of a LONG water pump to the radiator fins....on a 350SBC with the engine in the V8 position. Also, would like this measurement to a [2 or 3] core radiator, or at least tell me if you are measuring to a 4-core rad. THANKS!!!

Bomba de Aqua? We kinda hit on this subject about 3 weeks ago. I don't think we came up with a measurement to the radiator though but If I remember right the difference is 1 1/8'' between the short and long pump. If you use big block towers it will set the engine assy back 1''. Don't know if that helps you at all.

Have mine assembled now, so all I can give you is from the pulley that the fan mounts on to the 4 core radiator is 4". I have a 1" spacer with a flex fan on mine.

From the front of the pulley to the fins I measure about 5.5 inches. I have a 3 core radiator, 350 with a long water pump mounted in the V8 position... And from the rad to the fan clutch is about 1 to 1.5 inches.
