On your new cam, mild I think is good personal preference, and I could consider a short duration on both intake and exhaust. That would give you more bottom end power. For not much $$ I would consider a roller timing chain and new set of gears with the ability to “degree” the cam and set it four degrees before zero. Most of these guys on the forum could probably give you some good advice on the cam. I agree with the single carb advice already given… I think that a good 4 BBL carb would give you lot less headache, save money, and still give bunch of power
A buddy of mine had triples on a 300CI straight 6 in a early mustang.....It was more of an experiment and ran like a raped ape, but ridiculous to tune. Having them on a Jeep would be a headache.....but I guess it isnt mine.
Personally, get to know your Jeep better, like what kind of Tcase you have and axles, etc... as your time & $ can be better spent.
We got a 292 Chevy I-6 into the 13 second range with 3 webbers back in the 60s (it wasn't streetable). Six packs were once a common OEM option on muscle cars but they almost always could run a quicker ET with a single 4 barrel on the same engine.
Listen to the above advice; go with a small 4 barrel for better performance and more driving enjoyment.
...a well prepped, well driven, vehicle should do well in any terrain, including the highway.
Carburetors became obsolete during the last century... do what ever it takes to get fuel injection...It makes bigger grins off road.
I can't get one carb to run decent off-road on one Jeep. I can't imagine the PIA it would be to get 3 working right, at the same time on a Jeep. I think I'll stick with FI.
