We talked about putting LT heads on an LS to make a hybrid of the two, but how does that stack up to an LS or an LT? Which 5.3 is the best one to build? I mean there are more and more L83 LT engines in wrecking yards, as they have been the defacto engine in trucks and suvs from GM for nearly a decade. In some areas, they are as plentiful as the LS engines, or more. So if you have the choice between an LS and an LT with the same mileage, which one should you choose? And what if you have both and want to use something from each one? In this video you’ll get all that info from Richard as he has strapped all three varieties to the engine dyno at Westech Performance Group.
