Short version: I'm trying to figure out what these numbers and letters mean. I think I've figured most of it but not all, your confirmation / incite would be nice.
16197424 = ? 1994 454 Auto
BJKW = ?
partial VIN 1GA0571793 = ? most I could figure this TBI set up is out of a bus of some sorts.

Long version: I have a 1968 Chevy C10 powered by an 1970 Oldsmobile 455 backed by a 700R4 and a 3:73 geared rear end, power windows, power locks with remote, cruise control, vintage air heat & AC. This truck was built and upgraded over the decades by my father-n-law mostly with parts from the salvage yard he was part owner of. He mainly used it to pull his fishing boats and my wife and her sister also drove it to school way back in the day. When he decided he was going to sell it 16-18 years ago I told my wife I was willing to sell my truck and by this truck and use the leftover money to get her a new car as she was tired of driving a mini van. I'm a good husband that way;). As I was going to be daily driving it pulling my construction trailer I wanted a few changes made to it. First was pulling the heads and having hardened valve seats installed second was getting a wiring harness and the rest of the parts to install the GM TBI set up on it. We got every thing together and installed and it worked great other than a few small problems. Under full throttle acceleration it felt like a rev limiter was kicking in a few hundred RPM before the transmission would want to shift causing you to have to let up so it would shift and then get back into it.. Not a problem 99% of the time but when you're pulling a trailer into heavy / fast traffic that doesn't want to let you in it kind of sucked. After several years I quite pulling a trailer around daily and the truck got driven less and less. After awhile the transmission lost over drive (only) which made driving highway speeds difficult and expensive resulting in it getting driven even less. By then I was rocking a family of 4 and a truck that only seated 3 was a tough one. After a while my kids were old enough to start driving and to make room for their cars at our house I parked the truck at my mothers house. Where a pack rat decided that the EFI wiring harness on top of the intake was just what his diet needed. Now the kids are gone and I'm ready to start daily driving this truck again. The wiring harness will be an easy enough fix for me but the transmission is my next hurdle. I can rebuild the 700R4 and have someone get into the computer programing / tuning and adjust the rev limiter if that's what it is and be happy or I can swap it out for a 4L80e. Which as I understand it this ECM is capable of operating (after I build/ add the transmission wiring harness in). When we originally did this conversion the ECM was taken to a dealer to have the VSS deleted so it would operate right. Back then I thought / was told that stood for Vehicle Security System. I now know that is for Vehicle Speed Sensor, so I'm guessing if I go the 4L80e route I or someone will have to get into the program and make some adjustments or alterations for it to control the transmission correctly. One way or the other there is going to be the need for some tuning. I'm the kind of person that if time allows would rather learn how and do things myself instead of having others do it. The first thing I'm going to do is get it back up and running, then I'll figure out which way I'm gong to go with the transmission and that will tell me what direction I need to go with the tuning.
