168k mile junk LS1 motor

I was going through some OLD folders today and found this video of an old car of mine. Stock 50k mile motor spun a bearing (famous LS1 problem) so I found this old ass motor with almost 170k miles on it at F-body motorsports near Charlotte. Billy took me up there to pick it up and in 1 night, with the several peoples help (but PJ and I working around the clock), took the old motor/trans out, put the new rod bolts/heads/cam/intake motor/trans back in and had it running the next morning.

Video

The rings were shot as you can see it smoke after a full throttle pull. So I had to kind of clean it out with a few revs in between pulls. With Lorenz's help, the car ran strong and made great power for an old @ss junk motor.

The original tuner had it making 465/412 Rear wheel but the car was utterly un-driveable in stop and go traffic.

Lorenz worked his juju on it and made it 95% better and on this day it made 445/390 Rear wheel if I'm not mistaken. It had a hole in the tune somewhere but he never had a chance to get it perfect before he closed up shop and moved home.
