What all is needed to put a gmt900 long block in an 2003 rcsb new to ls swaps looking for info is there and easier way to run with the 0411 pcm than swapping crank and cam reluctor wheels

 

A knock sensor harness extension as the gen4s have them low by the oil pan one on each side and a 58x to 24x converter for the crank signal. Lingenfelter has one i believe.

 

They do have the conversion box

Lingenfelter TRG-002 58X-24X conversion module

 

Also cam timing will have to be adressed as the gen3 is 1x and gen4 is 4x as well as sensor location. I knew someone made it just wasnt sure lol ^^^

 

The box will do the cam signal conversion as well.

Just need the extension harness to pick up the signal in front of the timing chain.

 

Is there anyway to do it with out lingenfelter box I have herd a lot of bad news about it

 

I believe it was the first ones that were an Issue. They re designed the case to make it more heat resistant. Here is a discussion on tech were Jason Chimed in about the module.
58t crank to 24t crank - LS1TECH

If you re wire the Truck to accept a newer PCM. but its not cheap , or easy. Just ask Smokeshow as he did it on one of his trucks. I asked him about it and he said never again. It was a Pain to make everything work.

 

Appreciate all the info and I'll see if I can get in touch with him

 

I've used the Lingenfelter box before without issue, but this was last year so it was the newer style.
