Is DynaMat Xtreme enough or should we add 1/4” of DynaMat ?

Thanks Dave,I will take some photos tomorrow and send to you tomorrow.I like the guns and parachutes. I live in Pennsylvania and we are in the sights of the anti gunners. Ed

Say Dave here’s two shots of fan and shroud.

6 blade with no clutch? I think I'd swap that for a 7 blade with more pitch (I use one of these) and get a 1/2" shorter spacer, to put the blades about 1/3 into the shroud. Looks like you might also have an A/T cooler in front of the radiator? Should be spaced away from the radiator core up to an inch +-.
Good luck. Let me know how it's going.
BTW, the anti-gun folks are everywhere. We've got to educate them one at a time...
