Re: Budget Build 1985 K20

So after driving this thing for a couple summers now I love everything but the transmission. The turbo 400 with 4:10 gears leaves a lot to be desired when trying to keep up with traffic on the highway. It may have been fine in 1985 but in 2023 with 75 mph speed limits I am afraid I will get run over out there. It sucks because I sunk a bunch of money in it to get it built.

The plan this winter is to swap in a 4l80e. I picked up this beauty on market place for $200 and dropped it off to my trans guy for full rebuild and picked it back up this morning. I plan on getting a Hughes 2500 stall lock up converter and the Edelbrock proflo trans controller.
