The mags are Bendix S-1200 series usually found in high altitude turboed 540's but in 4-cyl form. With the towers so far apart, internal arcing is almost non-existent. Bigger coil than the more common 20 series, too. Great mags, just hard to fit in most small planes due to their length.

The engine is an aerobatic, fuel injected 360 (obviously). What did you want to know?
