Two more chemicals I use regularly over 50 years as owner/driver of antique and classic cars that are irregularly driven are: 1) Marvel mystery oil - added to oil- to quiet and clean the hydraulic valve lifters and hollow push-rods (It saves lifter replacement), 2) fuel system cleaner to clean carb jets, passages, fuel injectors, intake valves, spark plugs, and carbon build-up in combustion chambers. (Hint: Berrymans is the oldest and best in my tested experience). These chemicals work and save a lot of remedy-effort.

Funny you say that about the 73 74, I bought mine in 1993 for $1,500. When I went to the dealer for some parts the Parts Salesman said "Do you know what is good for the 1973 and 1974? I said, No! He said to crash them into each other and total them both. LOL Like I said above since the block was identically drilled thru I believe 1979 all parts were interchangeable, if you wanted to work that hard, but changing the entire 1973 Intake and Exhaust manifold back to 1972 was one day of labor. And well worth it until CA Smog caught the missing EGR even though it Smogged. The car was sidelined in my garage for 5 years until it was exempt from CA Smog. Then in Nevada to get exempt you have to pass smog once that only took 3 mechanics 2 hours to accomplish, but the car would then not run but it is now Exempt in NV.
