I'm running an HEI on my AMC 258 i6 / 4.2l , and I'm wondering if there is any way to waterproof it? When I rebuild my Jeep next year I'm gonna make good and well sure that it can perform double duty as a Jeep and a submarine lol. Not really though, I just want to have the reassurance that I can take it through some water if I need to and not have everything go bonkers on me. A buddy of mine has an F-AMC 150 with a 4.6 and you can't hardly take a piss on the wheel without having to stop and dry all the water out of his ignition, and I make alot of fun of him for it :laugh:
 
You could try a silicone adhesive on everywhere you don't want the water to get in, or lots of dielectric grease. A vent with a hose attachment would be good to add on to it.
 
Some folks seal up the cap/advance area with a non-corrosive butyl sealant, and then epoxy a small wire-feed welder tip in the cap, and run OBA at a low pressure through the cap...
