Unfortunately, there was very little OEM/aftermarket speed equipment released for the MEL Series Engine. The performance years for them was 58/59 and after that, they just became workhorses to pull heavy cars.
When LINC lowered the front end sheet metal in 1961, they also had to lower the carb mounting pad and reduce the size of the runners in the cylinder heads. The earlier pieces will not fit yours without some type of hood scoop.
About all you can do is a detailed rebuild paying close attention to CR and bearing fit, maybe have a cam reground to more modern specs, electronic ignition conversion and maybe a TBI FI upgrade.
There is a conversion kit to allow an AOD to be placed behind one.
