We have done maybe 50 LS swaps and most are so pleased with the increased power, smoothness, and fuel economy they think no further. This is for the "More Power" crowd. Replace the GM Induction and Controls with the Holley Terminator system. Difference is astounding. Just done a 6.0 aluminum Camaro/Corvette engine into a 3800 pound 70 Cutlass and it puts our 68 426 Elephant Hemi Plymouth to shame. The Plymouth gets 9-10mpg and the Olds will probably get over 15.
