Inliners International Forums General Discussion Engines GM 4 cylinders 151 153 181

OK, I picked up the '80 Jeep 151 today. It has a cross flow head like the FWD one I got on eBay but the bell housing pattern is Chevy. It has a coil in cap HEI with vacuum advance. It has a 2 bbl carb and a mechanical fuel pump. The bell housing has the Chevy pattern on the block side and what looks like Ford on the tranny side. It is complete except for the power steering pump and alternator. The guy took it out of his jeep because it didn't have enough power after he put 33" tires on it. It has 80,000 miles on it. I'm not sure but I think it should use the wide rear main bearing. If so it would take a 181 crank and be a 181. That is a gain of 30 ci using stock parts. It could also use a 153 or 181 head. I will get some comparison pictures posted soon. PICTURES
