Re: GMC 351 V6 "M" Engine Parts
A lot of the parts are the same. If you have a 351M, it came from a medium duty truck, 351E's were installed in light trucks 66-69. 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.
