A few ?'s while I'm doing the LT-1 to LT-4 conversion package.
Well I've got everything off my 95Z28 M6 and waiting for the LT-4 conversion package to come in tomorrow.....here are the questions.......
1. Anyone know a approx. cost on reprograming the computer for this modification?
2. While pulling the injectors I broke some of the little plastic spacers that are above the O rings...can I buy a kit to replace these and where...?
3. While my buddy was helping me he broke the opti-wiring plug..I sure hope I can buy this too....and I did give him a spack for being careless......lol
4. Will the stock push rods be ok to keep with this package..I've been told that they are already rated for 400-425 HP....
5. Going to replace the timing chain too.....I was told that another stock chain would work just fine....maybe or maybe not?

1. I use www.pcmforless.com. I bought unlimited programming for $75 and he emails the new programs. I also spent $35 for a non-molded cable to download the programs. So, total investment...$135 with as many changes as I need.
2. Don't know...sorry.
3. see above
4. Stock pushrods are fine as they are harfened. I would just check them for straightness on a piece of glass.
5. Stock chain and gears have been fine for me and a whole bunch cheaper. If you are just planning the LT4 conversion with no further mods (N2O, supercharger, etc) then you're fine.
Let us know how the install goes and what kind of improvements you get.

If i was you i would not skimp on the timing chain. I got my LT4 ED for 200 from gm parts direct and i believe jason cromer sells them for about 180 well worth it in my opinion not to snap a stocker and ruin your new LT4 heads. Also when your old crappy stocker starts stretching which it will very quickly you will lose the accuracy of your timing.
