273 engine swap into a Jeep CJ5

Put the Weber Progressive 2 barrel carb kit on your Jeep 2.5 carberated 4 cyl. That will give it some more fuel and wake it up.

Easy to do with these kits, lots lots easier than doing a V8 Swap Over.

Have used these Progressive Carbs many times with great success.


Running one on my performance built Dune Buggy, VW 1835cc 4 cyl Air Cooled engine with Progressive Carb. Always opening up the Secondary as a normal part of driving it.

Pulls Good, Runs Good . . .
