360 is still running hot
Tried that before I decided on the electrics. It only gave me a 1/4" more room which was about a half inch away from the fins at that point. Still made me nervous to run it. Especially if the fan flexed.
Not sure I mentioned this in the other thread,, but if your engine moves 1/2 inch forward,, you've got more than rad damage to worry about,, you've got serious body/suspension damage as well ..
IIRC the rear trans mount is "captured", meaning the steel attached to the trans will stop when it hits the steel of the crossmember.. You bend/break that,, you've hit something HARD, and the rad will be likely be the least of your worries..
As to the elec fan mounts,, how about some nice shiny aerodynamic tubing across the opening with the fan mounted to them or similar.. Just open it up,, any flat surface not directing air INTO to rad is effectively a dam,, a big dam,, blowing air sideways
across the small round areas avail, causing turbulence to the air trying to enter ... the faster you go, more deflection of flow..
As a side note,, my kid drives the snot outta his Dart, and at 1/4 in clearance, the fan hasn't touched the rad yet.. if it does,, I'll buy a new rad, and prob some body/suspension parts too.. lol
And really,, when you stated the clutch fan gave 1/2" clearance,, so it'd cost you a rad if you got that 7 blade to hit the fan,, choice seems straight-forward.. jmo
hope it helps
