1TrueSS Posted May 8, 2011 Report Share Posted May 8, 2011 Might need a ls1 style front drive assembly. The 5.3ls assembly has a high alternator and the accesorys sit farther forward from the block. Also the intake sites higher too. Quote Link to comment Share on other sites More sharing options...
Cordell Posted May 8, 2011 Report Share Posted May 8, 2011 Would have to have all the car stuff put on it, intake, accesories, oil pan, oil pick-up, windage tray, transmission won't bolt up directly, motor mounts would either need adaptors or swap k-members, I'm sure there is other stuff I'm not thinking of off the top of my head.

Chadz89GTA Posted May 8, 2011 Report Share Posted May 8, 2011 Everything that involved an LS1 swap would be directly related to this. LS1tech.com theres an entire sub section for engine swaps Quote Link to comment Share on other sites More sharing options...
99ta Posted May 8, 2011 Author Report Share Posted May 8, 2011 so if the 5.3 was complete with harness, you would still need all that stuff from an ls1? plus the kmember and new tranny? dosen't seem worth it to me.... Quote Link to comment Share on other sites More sharing options...
