I had one, thst was put in climate control storage with 2,000 Miles. It was purchased out of storage in mint condition for $28,000 (not me) and that owner had the engine "souped up" and dual exhaust. I purchased it in about 1990 with about 6,000 miles if that. I paid $10K. To me it was remarkably slow given the size and work it had done. It was a show piece. White body, white seats, red dash and carpet, Original red convertible top, black hub caps. Exactly as the original Cadillac dealer owner ordered it.
I have a cadi deville 79(7.0L 425cid V8) where I can find the a great radiator? any recomendations or maybe a number or something similar, thanks for the help!.
I have exactly the same car - even the colour. It had overheated and the driver side valves weren't sealing. Pulled both heads and got them sorted out but didn't look into the pistons/block etc . Runs OK now - still missing a bit - I cleaned the lifters but maybe should have replaced them. Transmission doesn't always seem to want to transfer power - like it's always in neutral - intermittent. Fluid is high, but if I drop it to the correct level, it seems to make the problem worse. Might be linkages. WIP.. Will follow your progress with great interest!
4 row copper/brass is best. I've gone aluminum with plastic tanks on my '76 Coupe DeVille and it doesn't perform as well despite the larger surface cooling area. It's possible I have other issues going on (clogged passages, tired water pump) but when I swapped in a 4 row copper/brass from Champion after going with the rockauto aluminum radiator not only was my wallet a LOT lighter, my coupe ran properly again (ie no overheating). very interested to see how you progress though, thanks for the video! oh and PS - the last 2-4 minutes are the into of your video again, FYI.
Great video, and very helpful to me. I just bought the same car with 23K miles. I changed the oil before starting it for the first time this spring. It is super smooth but there is a much, much quieter knock that is timed with the engine revs. It sometimes goes away briefly. Oil is full, no oil light on. Any thoughts?
Could you put an aftermarket EFI system on it? If a carburetor was on it, surely there is an aftermarket FI system that will fit... And there surely is a possibility that true dual exhaust system exists. Guess it comes down to what the owner wants to do with it...
Impossible on a stock (late) 500. The head is 120cc. It would destroy the valves before the head as the piston doesn't travel above the deck to reach the deeper chamber. These are non-interference engines. Now if you put late pistons on a early 76cc head, it's definitely closer.
