The only 350 I am seeing for a Cadillac Deville between 1977 and 1984 is a Diesel!
Nothing wrong with the the engine you submitted, that is if it is still in good operational condition.
Vehicles from before computers are a lot easier to repair and keep up, especially when it is time to pull your wallet out.
I suggest you have a 'Motor Head" of some sort look it over with you before you commit. Sometimes there is stuff you might overlook. Getting in over your head might depress you.
I have had nothing but Jeep CJ's for daily drivers ever since they let me on the asphalt in 1981. My present two were obtained in 1991. "Mr. Jeep" is a 1977 six cylinder (daily) and "Willy" is My 1946 Willy's (Driven every chance I get).
Payments (one for each)
Mr. Jeep $2,400.00 (road ready). Modifications over the years.
Willy $100.00 (two years later road ready). They all laughed at me when I brought him home on a trailer. They did not have the vision I had!
It is all in the upkeep and love you have for them, granted I have no car payments (no one has their hand in my pocket with time restrictions).I do spend money to do upkeep and improvements, but it is all on "My Time Schedule".
Best of all, things are not outrageously expensive, things are not all plastic, pretty easy on most tasks. Jeep parts will be around forever! Sure beats a monthly car payment (it is so much cheaper too!).
There is the "I did this all by myself" grin when you talk to other folks.
