I have installed 350's in a couple first gens. I have a 86 Blazer 2wd..my neighbor has a 6.0 and 4L80 for 700.00 any tips on what I need...do I need all the exhaust sensors? factory harness, or aftermarket? I know there will be a lot more wiring than a typical V8 swap and just modifying the stock s10 harness.
I have never had a LS series motor and heard that they are a good reliable stock engine with lots of upgrade potential, and I can still retain decent mileage over the typical carbed v8 swap...any tips? thank you in advance.
