I am new to the rebuild scene and would love some input in regards to motor replacement. I have an 86 CJ7 with Chevy 10 bolt wide tracks (3:73). Not going to be doing anything major as far as crawling, but I want it to be off road capable and a "daily driver" at the same time.

I have an "Iron Duke" and the lack of power is killing me.... (post #5)
Did I missing something? A stock 86 CJ should have an AMC 150 4 cylinder and not the Pontiac "Iron Duke". The Iron Duke will have the carb on the passenger side, AMC 150 on the driver side.
I would verify what engine and transmission you have. IIRC the GM 4 cyl engine (Iron Duke) uses a different bell housing bolt pattern than the AMC 4 cyl. Iron Duke = standard GM SBC. AMC 4 cyl = GM 60 degree (i.e. 2.8L V6) pattern.
Don't rely on my memory. Call Novak with your specifics. Top notch company.
Ty always - u r correct. I confirmed today after prolonged googling that I have an AMC 150. Having serious issues getting it to pass smog. Need some suggestions on how to boost HP for this lil guy. Heard that Redline makes some good carbs, but need other suggestions on how to squeeze out some power.
You could spend money on a cam, intake, etc, but will still not get the power of swapping in the 258 or 304, 360. Maybe someone could chime in about a turbo or supercharger on the 150ci? It would probably still be cheaper to swap a V8 anyway.
It is an engine, it burns fuel internally to provide power.
The 258 is an OK swap but it will turn it from slow into not quite as slow, it will not be a roadburner.
Could I suggest the mid 90s 4.0 HO from a Cherokee or Wrangler? You will need to do some plumbing and wiring to make the fuel injection and ignition work and swap out the exhaust manifold, radiator and a few other bits but it will give plenty of performance. As it is a development of the 258 it is a relatively easy fit.
The T176 is a good medium strength 4 speed from the early Eighties that will fit the 4.0HO and is a CJ original fitment. Plenty of other boxes out there as well but it will be well suited to the 4.0HO.
If you want to pep up that AMC 4 banger you may struggle. It was a bit undersize for a CJ but gave good fuel economy.
