Thanks guys!
Engine is cleaned up, new flexplate is here along with my mounts/harness/pcm from Yates EFI. They were/are great to deal with. Quick responses to email questions and the parts look great.
Engine cleaned
New Harness
Still trying to figure out what headers to run. Open to suggestions...
I'm also curious, can I "T" my return lines from my hydroboost to just run a single return to the stock ls1 power steering pump? I've searched around and can't find anything. Thanks!
