Hey, i was just wondering what i would need to change to swap my 350tpi into an ls1? What all needs to be changed? Thanks

 

The engine, harnesses, computer, sensors, transmission, engine/transmission mounts, fuel pump/supply system, etc.

Basically, you need to do an LSx swap, which isn't new territory - there's a sticky in the top section of the forum on the topic.

 

You cant use the same tranny? I thought u could

 

You can, although it's easier to use the 4L60E or 6-speed.

If you look at the LTx/LSx sub forum, there's a sticky.

 

It's on both forums, actually. https://www.thirdgen.org/forums/engi...want-swap.html

The input shaft length is different. Auto tranny requires a spacer, haven't heard of any solutions for manual tranny other than changing the input shaft.

 

Ok thanks. anything else i might need to change. After i buy the ls1 motor - what do you think it will cost?

 

Did you read the sticky?

I haven't checked lately, but decent engine/harness/PCM were going for about $2k; add a 4L60E another $1k; an LS1/T56/accessories/harness/PCM will run somewhere between $3500-$4k. Figure another $500-$1500 for installation stuff, depending upon what you do for exhaust, gages, fuel system, etc.
