Recently purchased a 1993 YJ, but found the engine has been swapped. ( Vin shows it as a 2.5L 4cyl ) I believe it may be a 4.2, but not 100% sure, and unsure of year? Intake manifold stamped ef 3237858, Drivers side stamped 145 83 and 930602373(on tag, on block), passenger side block stamped 306C01.Only other numbers I see are 86 R ( on top of head, front )
Any help would be appreciated! Once I know what I have, I can figured out what Carb - plugs/Distributor/Wires to purchase. Thanks in advance!
