Those who know my 91 was carb 5.3 but I changed and went to efi. Its 5.3 with lts, tbss,90mm tb.I just order my harness from psi for 580 and change not bad for pre-fab harness. But my? Is what lbs injectors be best for my set-up.its getting a cam later when tram put in.

 

I would try and find some stock injectors off of that intake manifold, but do you plan to add any forced induction later on down the road?

 

No.I'm staying N/A. I order my harness with the EV6 injectors connectors
