The GM 4.3 is about as solid as they come. I even preferred these over the older I6 equivalents.

Just to be clear, you are talking about/comparing to, the OLD GM I6, not the legendary 300 ci I6 from the Ford early days...right?

Having driven the GM 250/292 I6, a Ford 300 a few times. Also having owned a 4.3 TBI and vortex versions in an Astro and Safari van. Those 4.3s were better setup for mileage pulling power and speed etc than the three I6 rigs mentioned. As I am typing, I also.learned to drive in a 3 in tree 225 or there about.
Yes those motors were good in the day. No different than a 440/454/460 V8s of yore. Good at the time, but current motors are better.
I suspect current 4.3 will be on par with son's 4.8 V8, and similar to my vortex 350 in 2500.
