Wow, another super clean truck.
My 1989 roll back came out of New Jersey some years ago and has rust and a gazillion hours on it, but not a lot of miles. The wipers and power window motors are worn out and barely move...
454, carburated...air cleaner has a big sticker proclaiming GM paid a big fee for this not having a throttle body. 4 speed 4.36? gears ? Motor is quite tired and needs a refresh, but I have a "few" other projects ahead of that. As long as it runs and moves, it stays together.
