Looking to transplant a LS heart in the Marauder to really get it moving. Should be the second one (documented)

Kind of hung up on doing an LQ9 or a 5.3(l33) ...marauder already has a rebuilt rearend with 4.10s.

I wouldn't mind boosting or spraying either motor if funds allow. My first mission is to complete the swap clean with all factory gadgets working. I know I'll lose traction control but that's cool.

This will be daily driven and even highway road trips

 

Go for the 6.0. The extra cubes will help tide you over until you can afford boost.
