Upgrade mechanical fan vs installing electric fan

oldkimmer said

I run the factory 2 core 26 inch rad with a declutching fan from a 70 swinger 340. No fan shroud.Stays at 190. 470 stroker. 655 hp 622 tq. Block is half filled with hard block. 36* Celsius is as hot as it usually gets here. Only quarter mile runs though. It will idle for a long time without getting hot. Kim

One reason I have had heating problems in the past , is probly because of the 17" fan , I would have to relocate my 28x19 crossflow griffin and build another shroud to run a bigger fan. For the last of the summer I had it pretty well whipped w/ the mech. 17" fan tho-----still would like to run the clutch set up tho.
