Hopefully someone here can give me some assistance. I am looking for a 4.3 to put in my Jeep. What years were carbed? I don't want to deal with trying to hook up fuel injection so could you get a newer 4.3 and get a manifold and carb to go on it to replace the fuel injection? Any help you guys could give me would be great. Hope to be hearing from some of you. Thanks
The 4.3's in earlier Astro Vans were carbed ('85 or so). And you could get a later model 4.3, and install a carb/manifold. You have to stick with a TBI (Z) model, as from what I understand the CPI versions of the Vortec had different heads, with non compatible bolt pattern for the carbed intake.
You would have to go about pre-1986 to get a fully carbed model...
Personally I think the Jeep could use some sort of EFI model, but that's my opinion. If you have a 4.0 litre, incidentally, there are plenty of toys to put on that motor to make some really good power and torque.
Also, depending on what year vehicle you have, the typical thing to do would be to throw in a 350. That would require a little more playing around with things, but thought I would get the gears moving in your head about it! [img]/wwwthreads_images/icons/smile.gif[/img]

I just wanted to say thanks for the info guys! The motor is going into my 85 cherokee. I have the carbed 4 banger in now. The 350 idea is good but it is a pretty tight fit under the hood. That is why I chose the 4.3. I would love to go the F.I route but I am just trying to go with the easiest route for now. I am moving to Texas in a month so my time is limited. Well thanks again. Jay
