I never was much for M Block engines till i got my 78 F350. With just a RV cam, 4bbl, intake, and headers, higher compression pistons, and afew other goodies its a hellacious motor.
M engines get a bad rep because of some very late 77\Very early 78 Castings made at the cleveland plant (i believe) that had weak head\block castings that caused them to crack. If you have one of these castings its almost 100% your going to have problems. But the other 90% of M Blocks had no issues.
