My current daily driver is a 1997 RCSB. 4.3, rebuilt/shift-kitted 4L60, 3.42 open diff. It is slightly faster than a Power Wheels kiddie toy, but does tow marginally better...
What would be the easiest swap into it? I like the truck, have had it since I was 17 and want to keep it no matter what, but the V6 is getting pretty tired and has multiple oil leaks.
I was thinking an R-code 350 donor-truck and a long weekend... How involved is this swap (keeping the fuel injection)? I am also interested in other swaps: 5.3, 6.0 and others. I feel that the Vortec 350 would be the easiest, but offer the least performance. Does anyone have any advice, recommendations, or pointers?
