The "M" and "E" engines use a different intake and heads with bigger ports for increased air flow, the 351C uses smaller ports like the 305E. "C" and "M" engines (medium duty) use pistons with 4 rings instead of 3. There are plenty of parts for these engines around, it's just a matter of finding them.

Not easy to find around here. Everybody scraped them all around here. Too many people live by the day around here.
