Low compression 360 cam suggestions

I put the summit 6900 in the exact same spec 360 40 thou over dished piston motor back in 2012 when I built my motor and put on an edelbrock manifold and a summit 650 vacuum secondary carb and use factory exhaust manifolds with a single 2.5 inch exhaust with a single muffler ( I hate noisy droning exhaust on long drives) and run a 2.92:1 diff with 14 inch rims and 215/65 tyres
I get reasonable economy on the open road around 25 mpg and while not the quickest off the mark it is not a snail either, I built it as a cruiser not a racer
