Nice start to everything especially considering market. High pinion 60s are fetching $2500 alone. The carb if you are lucky might have the TPS kit on it. You can still run the 4l80e. 35s 4.10s and an 80e is a pretty decent combo for everyday driving. If you are really hauling something heavy out it in drive. Those trucks are hard to find at a decent price. If you are in a spot where you are not required emissions I would probably do a fitech or sniper system honestly instead of the stock vortec 454 setup. I would make sure it was indeed a vortec motor and 4l80e. If not there will be more surprises lol. Good find though.
