5.3 swap into 97 c1500 rcsb

Ok, Ive searched for about a week, found alot of good info, but Im still unclear on a few things. Here is what i have

1. -current performance will build me a new harness out of my factory 97 harness so everything will plug in, no splicing at all, they will even wire in the elec fans. i talked to nelson, but basically, she said they would build be a ls harness and computer and I would have to tap in for gauges etc, so which is better, not much about current on here, but it seems to be the better harness, both prices where pretty close

2. - i know i need a bracket to relocate the ac, but will the other accessories off the 5.3 clear the frame fine?

Thanks in advance

I have been searching for about a year on doing a swap and as far as a harness goes, I cant help. Maybe someone will chime in soon. I am building my own harness.

As far as other accessories, yes they will clear. From what I can remember is if you retain the 5.3 truck brackets then they will clear. AC is different as you have already found out.

Yes, they will clear but you might ned to change the oil pan for clearance.

the factory 5.3L fullsize truck oil pan will clear as will the factory exhaust manifolds cats and y pipe. i'm in the finishing stages of my 5.3L swap into my 92 GMC k1500 with 98 interior and wiring and the 5.3 fits like a dream. Here's a few pic's that might help clear up a few of your questions. Ans building your own harness is not that bad of a job just very time consuming.

Well, I guess im gonna order the Current performance harness, they are the only ones that seem to have the answers i need about my harness, Ive tried to call Nelson several times and half the time, i dont get an answer and the other half, I get a ladie that tries to help me, but really doesnt have the specific answers i need. I want to deal with Nelson, But I can get anybody on the phone to help, If they are this hard to get ahold of when i want to purchase something, imagine how bad it will be if I have a problem. Not trying to down anyone, just sharing my personal experiance

You should have asked for Jonathan, he's the man when it comes to wiring. :thumb:

I finally got ahold of johnathon last nite, Im probabley gonna go with Nelson, Price is better and they seem to have more knowledge of my build, Im just a little reserved after how hard it was to talk to someone

Bellflower,
I am working on a bracket kit that will allow the stock A/C compressor and lines to be used on a 96-2000 GMT400 Gen3 engine swap
If you can wait a couple of weeks, I will have something to show you. I don't mean to disrupt your thread--Enough said.
