While the 4.3L might not be the most famous GM engine size, it surely does have a lot of history for the brand. We’re talking about the 4.3 V6 we’re used to seeing, a 4.3L inline 6, and even the 4.3L V8 that came in fullsize B-Body GM cars. But which one is best? I mean I love the turbocharged 4.3 that came in the Syclone and Typhoon. But the 4200 inline “Trailblazer” engine is also one bad mother when done right. Watch the video and see what the tests done by Richard Holdener show.
