Clutch fan options on my 340?

Yeah i want blue prints for a proper size fan shroud lol and the accetable tolerances between the fan and shroud and fan and radiator.

I always have and always will run a shroud

Ok so it looks as though the MP viscous fan setup is almost non existent. Classic industries says available soon but who knows when that will be. So i guess theres no sense doing anything other than the MP setup right? I just dont trust the other options for clutch fans as hayden cant even reccomend a fan for their HD 2947 clutch which from other threads on here had pretty much been made for mopars. But no fan to match up to it.

However if i could find a used MP 5 blade i could use the hayden clutch anyway and it would be more or less the same setup
