95 LT1 into 93 TBI van

I just picked up a 95 LT1 Cop car engine. Iron head. I have the complete engine, wiring harness, PCM and accessories. I just scored a set of factory service manuals for the 95 Caprice off Ebay to go with my Astro manuals. The wiring harness is very intimidating. Much different than my CPI to TBI conversion. Does anyone have any write up about your LT1 swap and/or pics? Mainly I need a starting point. How much of the harness will I need to use? How did you mount the accessories? Do you know how much crap I can get rid of on the engine? This damn thing bent my engine stand it is so heavy. All I need emmission wise is cats to pass inspection. Thanks for the help.

AstoJoe, that is one sweet ride. This is my first time on the site and just signed up.
I love the way the LT4 motor looks.......reminds me of a TPI injection on steroids! :rockon: Just wouldn't want to dish the money out to rebuild one of those motors.
obdII has 4 O2s.
obdI has 2 O2s, but the '94 and '95 LT1s can have a obdII aldl connector but running for a obdI system. confusing and "Back to the Future"
'96 all GM PCM was OBDII
'95 pcm is the best i am told for it's simplicity.

the LT5 looks similar to Tuned Port Injection (TPI)

OH shot your correct LT5 :doh:

& it looks right at home in a 3rd gen:

does the LT5 drive the 4 cams like the North-Star?
(chain and sprocket?)
