I have swapped a gm 4.3 into my 86 MJ. I used the Novak motor mounts and redrilled my factory transmission support/ crossmember. I have plenty of clearance at the front of the engine and I'm looking for advice on the radiator. The radiator had over 280,000 miles on it when the 2.8 finally went. I've already dropped in the 4.3, mated 700r4 and 231C from a gmc s15 jimmy. Will the stock style 2.8 radiator cool the 4.3 or will I need to upgrade? If I change to the 87 up radiator, will I have to change my hood latch/ front end? Thanks for the help!
