Hey guys I've been searching to find an answer here but seems a different answer from most people. I have a 1997 4L60E from a v8 and I'm wanting to put it behind a 2003 5.3 LS . What do I have to do to achieve this properly? I hear I need an adapter to space the torque converter to the flywheel, and I may have to elongate the bolt holes on the flywheel. Is this all that needs to be done? Any and all feedback appreciated guys. I'm a new member here and am doing an S10 build. Thanks in advance guys. Best site I've seen for information on this type of swap. Also, I want to upgrade the torque converter with about a 2500 stall. Any suggestions?

 

also do I need to use different starter or will the one from the new LS engine still work for this application

 

Add crank spacer and elongate flexplate bolt holes. Stock starter will work.

I always measure converter to hub to trans bell housing mounting pad. Thin measure rear of engine etc. This will make certain if u need a spacer or not.

 

ok yes I did find the adaptor for the flexplate and I have the dished flexplate on mine. So from what I understand I do need the spacer. I have the old flexplate as well from the 97 set up so I will e able to trace to elongate the holes.

 

Treat it as if you're dealing with a th400 swap or similar. You need to use the correct year converter to match the trans...then get a crank spacer and flat flexplate with the correct bolt pattern. Very simple.

I hate elongating the flexplate holes...but I know people do it.
Make sure to doubecheck converter clearance and pilot hub engagement.
