I am doing a LT1 swap in a 67 cutlass with a 330 olds engine in it. I am putting a 4.3 LT1 of a 96 caprice in the cutlass. I am having some trouble identifying some of the plugs. I am looking on that lt1 swap website but still having issues with telling what wires that I need to get the car running. Any help would be appreciated

 

Uhh buddy, the 4.3L isn't an LT1. it's an L99. The 5.7L is the LT1.

 

But it looks virtually the same with most of the same (if not same) connections.

OP, look at this wiring harness link and see if it helps.

 

Thanks I had been looking at that pic. Just trying to do it right the first time and not mess anything up.

 

in future questions just pretend it is an LT1. The ONLY things you will accomplish mentioning L99 or 4.3l is getting less information and more bad information from those who will refuse to believe it is the same other than displacement which wouldn't matter unles you were talking internal engine stuff.

 

Thanks a lot for clearing that up for me!

 

I'm going to install a L99 in a 68 convertible with an M29 and 3.55 rear gears.
