" . . . according to the numbers this is a 235 from a panel truck from 1953." Neither Panel Truck in 1953 had a standard or optional 235. What are your numbers?
The 1953 1500 series Station Wagon and Sedan Delivery had a standard 216 engine. A mechanical lifter "regular 235" was available as an option on some models.
The Powerglide option was not available on a 1500 series vehicle, but a heavy duty manual three speed transmission was available on all cars/wagons.
The Powerglide and hydraulic lifter 235 was only available on 2100 and 2400 series cars in 1953.
Post the Engine Serial Number - it is pressed into the block in the ledge to the rear of where the distributor goes into the block. This might allow someone to ID your engine/transmission.
