I actually purchased a Jeep Cj10a aircraft tug a year ago with a factory sd33 like in my dart, and the head had been pulled and by that point the motor was toast.
Just last week I installed a turbocharged motor into the tug, and I’m hoping to get it all finished up and running and I’m interested to see the difference in output. The turbocharged motor came out of a 1980 scout, and was mates up to a 4 speed, and for my Jeep it’s mounted up to the factory 727 torqueflite, again, the same setup as my dart.
