Looking for more pep off the line
The wide 114 LSA is a torque killer. Moving it to a 108 will add torque.
The smaller barrels of the 650 limit air flow. The car will not have a significant mileage loss with the bigger carb. Just tune it, re jet it accordingly.
While I can’t stand the company “MSD,” a multi spark ignition will add everything they state, easier starting, better fuel economy & yes, power. Even if you don’t have a multi spark ignition or any upgrades to it, you have to make sure it is in top shape. Some power (just a little bit) can be found with a wider or bigger plug gap. This will require testing the changes over and over a few times.
If you don’t find a camshaft with a 108 centerline, you can call the cam company and ask for it to be moved from the typical 110 to a 108 or 106. It is a nominal fee, cheap. I asked Comp Cams to do this on a XE285HL for me. They said, No problem! There was a small lead time of a week. Sent straight from Comp.
You didn’t mention if you had headers or not, but they do add power everywhere. IF! You decide to do headers, the best and among the least expensive units I suggest and use are a set from Summit racing. While inexpensive, they do have a thicker flange @ 3/8 thick and have always fit well. I’m running a set right now on my Duster. I have them coupled to a Summit exhaust at 2-1/2 inches. Minor trimming is needed. There exhaust set up is quoted to be used with Hooker headers, pay no attention to that.
