Thread: Motor Mounts: 351W vs 351C

Tweet

Are the motor mounts the same bewteen a 351W & 351C?

Will the Cleveland motor drop into a 70 Mustang ( 302) without any major modifications?

motor mounts aren't the same... but motor mount brackets are... so you will have to buy motor mounts for your motor from the parts store... shouldn't be more than $35

You will need an adapter for the bellhousing also. The Windsor is a small block and the Clevland is a big block, completly different bolt patterns. Also you will need to look at the radiator and where radiator hoses connect to the water pump. One more thing, the exhaust will be different because of the wider block.

the motor mounts will bolt up without a problem , your bell housing will bolt up too. The exhaust manifolds won't work. you will need the alt. and pump brackets from the cleveland

The Cleveland is basically a Mid-Block and partial to the Modified Engine Family (351/400M engines) The trans is the same as all the small blocks and the engine mount bosses are the same too. However, i believe there are specific motor mounts for puting the 351C into the stang that lower it down just a touch. So the mounts you have from the 302 will probably work, but won't necessairly position the engine correctly. Give it a try, what the heck?

obviously the exhaust won't be the same either but there are headers available or go with early casting 351C manifolds for the best clearance.
