Post need help!!!!

I recently obtained a 1972 280se with a 4.5 in it. Car ran great for the first tank of fuel.Took it to work one night, ran great all the way home except for the last mile. I decided to step on it and see exactly what kind of speed the ole girl had in her. Ran it up to about 70mph and let off the throttle and the car started to miss and sputter.I made it back to the yard and decided to check the points on it, every thing looked in order but discovered the vacuum adv unit needed replacing. Put the new one in today but didn't do much for it. Car acts like it is flooded now and barely runs.I was wondering if anyone here can give a shout and help me out. thanks

Just a guess but you can go through and lube all the joints and linkage maybe something stuck also check all the ports on the intake to see if maybe you have a vacuum leak
Honestly just guessing but that be starting points

Take a look at the online resources portion of the forum. I posted a troubleshooting guide for our engines there.
