This is for all the hard core hobbiests out there... I'd like to know what engine the most folks prefere to install in their JEEP's, Non stock engines that is. I have had a jeep with small block chevys since the early 70's but the 327 has a cracked block so it's engine time agian. I have a buick even fire and a chevy 454 sitting here should I decide to run either, but I hear that the Chevy V6, "shorty small block" is a real good choice. I'm not too sure the big block will fit in the thing, it's a 55, kind of narrow frame. Anyhow send some feedback and let's see what's being run out there. Mo 04-13-2002, 08:08 PM small block chevy v8 is probably the most common engine swap out there Other popular swaps are AMC V8 (easy bolt in to later CJs) Ford 5.0 and Chevy V6 (4.3L) For some of the early CJs (Pre amc era) the pinto 2L was a hot swap (check HighHooder's jeep) oldjeep 04-13-2002, 08:14 PM For flatfenders and early CJ5's the buick V6 is a good choice. You don't have to hack the firewall up to get it to fit, and there's plenty of power. yjtj 04-13-2002, 08:37 PM small block chevy is about the most popular swap for anything 64Trvlr 04-13-2002, 11:35 PM On the 7 CJ's I've owned, 6 of them have ended up with a small block in them. :cool: Gozuki 04-14-2002, 12:54 AM I love the 5.0 HO EFI... mtndewmaniac 04-14-2002, 01:10 AM The most popular swaps have been the SB chevy, and the Buick V6s, respectively trickrock 04-14-2002, 12:29 PM Originally posted by Gozuki I love the 5.0 HO EFI... The Ford 5.0 is the best v8 for a swb vehicle, 100lbs lighter then the chevy 350 and just as many if not more performance parts are available for the ford! The transmission choices are abundant as well. I would also guess that the Ford 302 is actually lighter than the jeep 4.0! ...but I don't know what a 4.0 weighs:confused: CJ-Jeeper 04-14-2002, 07:08 PM If you already have a SB Chevy, why put somthing else in? Too easy? Mr.N 04-15-2002, 05:42 PM If your going Carb, stay with a Chevy. If you want EFI, the Ford is MUCH easier to hook up. There is even a book for how to install a 5.0L into a non EFI vehical :) 1RUSTYRIG 04-15-2002, 08:35 PM I bought a 4.3L v6 off of ebay for $1K. It came COMPLETE down to the spark plugs. It is a 1996 with TBI. It is brand new and sold as an overage from GM. Dyno'd and balanced, but never installed. You can grab an ECU and wiring harness from an s-10 or astro van for about $150.
