Default Here are some pics of My 94 Z28 LT1 engine rebuild

Here we began in the driveway, for all you guys who don't have a shop, you can do it !! and it will take all night long too... LOL

Total cost was around $5,000...$2,300 for rebuild and another $2,000 or so for opti, starter, alternator, plugs & wires, harness for opti, all coolant hoses, ALL sensors everywhere, harmonic balancer, ECM, ect...
Could have had a more powerful engine but I wanted to drive it alot and on long trips, plus Grooms warranty of lifetime unlimited miles kept me stock....

Wow, CNCman, I'm in a parallel V6 universe. Same year, same color car, same t-tops. I'm just missing two cylinders!
I did virtually the same thing you did but dropped everything out the bottom and didn't touch the trans (budget).
I painted my 3.4 Chevy orange and did a similar underhood cleanup. I've been driving mine a little bit and that 3.4 is nothing to scoff at. As a daily driver it is more than adequate. I'm sure the LT1 is a blast and a half.
I need to get an alignment and the a/c charged before mine sees daily service.
For me it was almost 09 months from pull to turn the key but I pulled the crossmember and front suspension then blasted/painted that stuff prior to reinstall. Plus new control arm bushings, balljoints, sway bar links, etc. Oh, I had my original engine rebuilt instead of swapping one in. That slowed things down a bit.
