i will say that the 4.3 g.m. beats the pants off the ford 4.0 hands down. the 700R4 trans is also miles ahead of any ford O/D auto trans available with the small V6's. if i had to re-power, id be real tempted to go with a 4.3/700R4 combo (since the cummins 4BT would be tons more work than money, even if it would be the ultimate power plant) ive always been of the opinion that chevy motors were easier to work on, but the fords didnt need as much work nearly as often. reliability wise, ive not had alot of major trouble with either, just small irritating stuff. only motor i ever blew was a 2.3 tempo that rattled like a diesel the whole 3 months i had it, even when it tossed a rod (and took out the one next to it) it kept running on 2 cylinders and got me to the next parking lot.
