New carb and manifold or efi?

Post by mahoganysnow »

I have an 83 Cherokee with a 77 AMC360. I know the engine was bored 30 and I think there is a performance cam in there too. All work done before I got her. Still has stock manifold with a Holley carb. I’ve run into fueling issues, idle won’t settle down and runs rough at start up then a high idle after warming up a little. Cleaned gunk off linkage already and I was going to swap out fuel filter and rebuild carb but since someone else worked on her before me I was wondering if I should just get a new Edelbrock carb and manifold but am now thinking maybe go efi? Or EGR or non EGR manifold? Looks like some of the emissions crap was deleted as there are a couple lines that are sealed off coming off the manifold but I’m just guessing. Will get some pics on here if needed. Any thoughts or advice appreciated. Hoping to get this all done myself but it’s kinda cold out to be out there fumbling around scratching my head. Thanks.

Go with an Edelbrock intake and EFI, if you can afford it. Or the Summit/Street Demon carbs are good for street use. A Holley Truck Avenger for offroad.

I'd stick a holly sniper or a fitech on there and let the computer O2 sensor deal with it.

I can't remember which one, but they just put out one for a 2bbl intake so there would be no intake needed.

There are some really great (mostly) turnkey EFI solutions that even offer timing control right out of the box.

If you can install a radio, you can install an EFI system. Some even offer a "no weld" O2 sensor option, but it's easy to ask your local muffler shop to weld an O2 bung for you and there are less chance of leaks that way.

Sniper EFI. They have a 2300 style 2bbl that would bolt on in an afternoon.
