Good Morning I have a question. Good friend gave me a 351m Engine and Transmission it has good compression and has low miles and was rebuilt..The accessories are on it.Im going to change the Durospark **** and go with the HEI.. BIG QUESTION IS DO THEY HAVE A MOTOR MOUNT TO USE IN THE MERC AND What about Space not running Headers..Thanks Not a 390 IT A 351M ...
I have a 351M in my 56 Monterey Wagon. Stock front motor works fine. Driver side stock exhaust manifold is a tight fit. The p.o. cut a notch ( and welded ) in the rear to clearance the steering box.
The 351M is a DOG ! ( rated at 155 hp ) I totally re-did the motor. Edelbrock RPM Aluminum heads, roller rockers, r.oller cam, Airgap Performer intake manifold. Headers will be installed this winter. Running a Lentech AOD in place of the C6. Lokar throttle and shift linkages
I wished I had known about this ford mess...I might have to go with it..I'm just going to Cruise with it and a little highway driving
These engines aren’t that hard to wake up, a 4 barrel intake and carburetor and a set of headers are easy to bolt on. A camshaft change will also do wonders but is a little more involved.
I understand that..I just sold my ProStreet Cutl*** and I'm done with high performance..I just want to have a Cruiser
I’ll bet if you advanced the cam 6* you would not believe it’s the same engine. This era retarded the cams for emissions.
Their not bad engines. Just a bit heavy and Unfortunately they were hampered by having to comply with the new emissions requirements of the seventies. Their basically a tall deck Cleveland with low compression and retarded timing but they powered millions of Ford trucks and the larger Ford/Mercury/Lincoln cars of the era.
The distributors were also retarded to match, back then a swap to a Mallory or Accel would really wake these smog motors up along with an advanced timing set.
