Excuses, excuses! I am a day or so older than you. A 1937 model. I drove my 1950 Special TO and FROM Tacoma , WA from Texas 19 2023. 4600+ , if I remember correctly. Last year, from Texas to Iowa and return to see my first great, great grandchild. 3500+. Both trips towing a teardrop.

If the convertible shown is the one referenced, yes, the engine will be a 248 if it has the original engine. A 263 from 1950 or later will fit right in. A picture of the driver [ manifold ] side will help much.

With respect, can you post pictures of the engines? Drivers side showing the water pump and lower cylinder area? Passenger side with the engine number?
Thanks
Ben
