Stock Radiator Fan or Electric Radiator Fans

[RJRENTON]

I drove my GTX from February of '68 through January of '73 and put over 100.000 miles on it and NEVER had any cooling system issues. Factory 29" radiator, (4 speed car) factory clutch fan, and factory fan shroud.

Everything's still on the car.

The B BODY GTXs never used a 29 inch radiator (unless previous owner changed core support and used a C body radiator). The biggest was a 26" max cool radiator (more tubes on closer centers) with a 7 blade fan, toque drive fan clutch, shroud, hood to core support seal, standard equipment with the A34 super track pack option, FPDB, 4.10 Dana 60 rear, PS pump oil cooler.......exactly the way my original 1970 GTX, RS23V0A****** was built.......

Yes, install the shroud. Without it the air just swirls around the fan blades and nothing is drawn through the rad. These systems were engineered to work, and they did unless there was a maintenance issue such as restrictions to coolant flow. It also looks so much better the way they were designed.

I have NOT read this entire thread, so take my opinion for what it is, an opinion....
Factory fan, fan clutch, 26 (or more) radiator, (I'm using a high efficiency 28, from a big block cordoba) and a SHROUD.
Done.
Horsepower loss will be undetectable anywhere (except MAYBE a chassis dyno, and I doubt that).
I have two electrics on one of my cars, ONLY cause the radiator is at a 30° angle. (And no shroud is available for a dually radiator in a big block Opel GT)
The other has a mechanical fan for cooling, and an electric pusher, ONLY for between rounds cooling (usually unnecessary).

Yup... I would go to the beach on hot July days in my Mopar those days, never an issue with the OE setup. The only thing hot was the weather and my girlfriend.
