- 1986 Jeep CJ7 4.2 liter, 258 I6, 4 spd, 4" lift w/ 35" tires, 40k original miles
I have a '86 CJ7 w/ 40k orig. miles w/ carb. I been told I broke a connecting rod. I will need to pull the motor. Should I rebuild my AMC 258 i6 / 4.2l to stock? Look for a donor vehicle W/ 4.0 and EFI and rebuild that? Rebuild the original block and put a 4.0 head on? Then the question is which Which EFI, Mopar MPI or Howell EFI
