Here is the 1963 Econoline brochure.

The auto and 4-spd. were not available until 1964. The only tranny available in 1963 was the 3-spd. Tranny code A.

The 144 had 85 HP. The 170 had 101 HP. The door tag on Econolines lists the HP. My door tag says 85 HP and I have a "T" engine code. Based on that, the "T" means the 144. Even if the engine has been switched, the tag would still be accurate.
