4.3 TBI to 5.7 TBI
Hello,I just joined this forum. I have a 1991 Chevrolet S10 with the 4.3 TBI engine. I was wondering if anyone has ever swapped out the 4.3 TBI for a 5.7 TBI instead? If so, what all would be involved in doing so and is it worth it?

I wouldn't do it. Too much trouble and could snap the axle shaft or driveline, particularly with a stick. I'd just trade up to a C/K 1500.
