HEI vs TR
I'm looking for opinions on this. I've done the TR Upgrade to my 87YJ and it seems to work OK, although I don't notice any big improvement, if any at all. I have gone through 2 Modules since doing the conversion(the NAPA brand that came with the Jeep and a Wells-AutoZone) since last summer and only 1500 miles. I'm not saying it has anything to do with the TR upgrade but I'm thinking I'd like the supposed overall reliability of the HEI over the Motorcraft.
