[kewljay223]

Man I thought I had all the parts too before I started and let me tell u, I wasn't even close. Hell im about to put in another order today at summit for more... (i think that will be the last of it) and I thought it was gonna be a week also.... Its been almost 2 months..... But I also have a crazy work schedule. Stuff comes up. Be prepared for that. Its true what they say, it always takes longer than u think. But hope you can make your projected timeline! Post pics, progress, problems and everything. When u plan on starting? Next monday?

I am going to start modifying my harness to standalone tomorrow. The flywheel adapter and motor mount adapters are already here. I have my stock engine sold for $600, the guy already paid me so I just gotta get it out.

I have so much stuff listed that i was scared to order it all. But the totals were much lower then expected. Since I decided to use stock manifolds and cam for now, I have only spent $900 and thats with the 5.3 engine. Headers, cam, and performance tune was cut out of the build.. Just sent pcm off to have vats disabled and emissions stuff removed. Not bad for less then $100

I am on the same boat as u are. I started my swap of a 5.3 into my '94 W/T 6 weeks ago and plan on keeping my 4L60. From what I have read too, u can swap out the trans internal harnes to that of a later one, like a 1998 and it can be controlled by the LS pcm. The bad thing about '94 and older 4l60, is that they have PWM. Its suppose to soften the shifts. Mine does not have it. I also read on one of the treads, that u can simply have the PWM removed from the PCM when u flash it. That's what I plan on doing when I send it out to the guy at lt1swap.com in a few weeks.
