Ls swap
 

Hello everyone,

I am not familiar with LS engines and I am looking for opinions on what is the best LS swap for 1972 Blazer 4x4. Factory LS and not aftermarket.

I have been told that there are drive by cable and drive by wire. 5.3 to 6.0. Should I run factory or aftermarket harness.

I want torque and HP in 350 to 400 range.

Will be running 3.73 gears and probably/might consider 700R4 with overdrive. Current TH350. Will I need a transmission adapter to run 700R or TH350?

Thanks.
