Title: Reverse cooling a Windsor V8
Post by: fmd on July 07, 2011, 11:42:34 AM: Has anybody out there reverse cooled a Ford Windsor V8?. I ;m pretty sure I;ve worked out how to do it and what to use to cool it properly. The only problem is getting the right water pump. Has anyone got any email contacts for Ford Motorsports in the USA asI need a special length pump with an 8 vane impeller not a stamped steel one.
Regards Shane

i feel like i'm missing something here.

The reason why you'd want to bother doing this? Coz that's where I am. LOL

this engine doesnt look like a normal backyarder and the setup would be expensive and fiddly. there must be some merit in it.

does reverse cooling make any difference or does it just mean the block gets all the hotter coolant instead of the heads? i have an alloy radiator, huge thermo, electric water pump, custom timing cover etc etc and i cant keep the windsor in my car cool.
