Default Repair/ modification on a 30SK-18R

Got to do some repair on my SK, it's developing a crack in the exhaust manifold, and don`t have a spare. Being a Mopar nut, I have some options... I have a complete Super-Six factory 2bbl int/exh setup I'm considering using. From the wild side - I also have a complete factory Hyper-Pak 4 bbl setup, I'm probably never going to use anywhere as I'm more a 440 kind of guy. I have a decent stash of Impco mixers, 1, 2 and 4bbl types to work w/. I want to keep this Tri-fuel.

I also want to dump the propeller on the front of the engine, most of the noise from the unit comes from it. I want to R/R the mech unit w/ a 12v electric unit, w/ a custom 2 stage controller that I build/use on all my vehicles ( I run Ford 2 spd Taurus/Lincoln fans on everything but my Jeeps, (they won't fit those), common and cheap in the wrecking yards, quiet too).

One last upgrade: R/R alt setup to a 90-120 amp modern Denso unit. They charge better at low rpm and are very common in wrecking yards. I use these as an upgrade on my vintage Mopar toys and for clients rides, they work great.

Noise......Could try reducing angle of fan blades. If they used same fan as from a car the angle of attack for fan to air would be different in still air vs car doing 60 mph.
