On today’s video, we’re working on a new project for the channel. My dad picked up a 1973 Cadillac Eldorado Convertible with a 500ci big block and it’s cosmetically perfect but needs some mechanical love. The carb was changed out a while ago with an Edelbrock unit that was too small, and the power steering pump leaked terribly.

I was told by a power steering engineer to always jack the car up and do it like that on any car when replacing unit
Another issue that showed up as those engines gained age and hours was the nylon/plastic material that was applied to the camshaft sprocket that would deteriorate and allow the camshaft to get out of phase with the crankshaft. Result would show up in an ignition timing problem, among others. If another distributor/advance mechanism doesn't fix your problem you may want to chase this possibility. It is possible to change the sprocket without removing the engine but it is necessary to lift it enough to allow removal of the oil pan in order to gain access to the engine front cover, etc.
Sweet car! I have the same car, but 72 it’s on my channel
The car brings me back to the 70's. My neighbor had a 73 coupe triple red. That folding top is an engineering marvel!
The stumble is caused by the accelerator pump not being able to deliver enough fuel. The Quadrajet though is an excellent carb(I like them even more than a Holley)and the one for the engine in that car should have about 800cfm(they had from 780 to 840 rating depending on hp) air flow rate. The compression ratio is low too on those motors so the distributor curve is really important to them. You mean the choke was sticking closed? Ah…you figured it out. Get a HEI distributor for that engine. It is head and shoulder above the Pertronix.
The secondaries opening on a quadrajet are one of the great car sounds out there! Merry Christmas!

Is that qjet a new repo Chinese one or a rebuilt?
Your video brought me back to the time when I was a Cadillac factory field service representative (starting in the early seventies). You might want to jump to a 1974 HEI distributor which will fix all of your ignition issues and are still available since the system was used for many years. That upgrade was very popular back in the day and for good reason due to its reliability and additional performance. Oh, I started watching your channel because I'm in the midst of restoring a '66 Corsa. Small world, eh!
Merry Christmas to you and your family , cool ride !
