[trmlmm]

hey guys new to this site i have some questions about putting a bigger motor in my 1980 CJ5 i want to put something thats fuel injected the carb is having problems crawling and mudding due to rough terrain. i can get a 1995 chevy 350 5.7 1500 its tbi and i wanted to know what should i do to fix this problem off roading and crawling what would be the best motor or plan to make my cj better on the trail its strictly an offroad toy

would appreciate all advice

Might not want a 1995 motor. 1995 was the transition year from OBD I to OBD II computers. I have a 1995 4.3ltr TBI motor with OBD I. I had a hard time trying to find a code scanner that would read the codes. Found only one.

any fuel injection is going to be waaay better than any carb.
I have tbi (OBD 1) on my 350 and it's worked great for offroading.
IMO OBD1 will be easier to wire up as the computer doesn't use as much info to run the engine.

^This^ on all levels.

Unless you're pretty experienced with engine swaps or working on EFI engines, I would go with an OBD1 EFI. They are very simple and user friendly...pretty much like a carbureted engine with a few more wires, but much smoother running.
