You might want to pop a side cover, pull a lifter and look at the cam lobe. If it looks worn it's not too hard to put a new cam in and it will really wake it back up...

Well, '68 was when the redesigned monojet was introduced. I've found it easier to work on and it performs well. It's a direct bolt-on so I did that to my '67.
I had a '70 Bel Air with a 250 that was not well maintained. It ran, but didn't have a lot of power. I popped a lifter out and looked at the cam lobe. It was worn way down.
For not much money I got a stock replacement cam from JC Whitney and popped it in. Now the valves opened all the way
. Made a noticeable difference in power.
