95 OBS 1500 350/454 Swap

[Lennyobs]

I’m swapping a vortec 454 that I acquired from a 98 RV with 54,000 miles motor is in really good shape that’s why I’ve decided to swap instead of an LS. The truck is a 95 had a vortec 350 in it. What all do I need to do with harness to make it work. I also have the trans from the rv which seems to be a 4l80e I have engine harness from rv but it was cut when removed and I have both ECM that came with donor

Stripped down front end to replace every single steering & suspension component and laying down some POR-15 to clean it up a bit.....still debating to carb the 454 or find out this harness dilemma

keep the 454 modify as I go want to get a baseline feel for it and then chase some power on nitrous

Could just get a harness from a 454/4l80e gmt400? Otherwise you'll just need to find a schematic that lists everything out.

Yea that’s what I was leaning towards but I’m going to go the old school route run a carb on it

It would be a shame to carb it.
