Hi,

Was wondering if a 351M from a car is the same as a 351M from a truck. I read in one of the posts in this forum that the car and truck had different configurations for the oil pan.

 

Other than the pan...and I have yet to see a car motor, they should be the same.

 

The truck blocks have a reinforced bearing area and are identified by their D7TE castings.

In particular, check out the Cast Iron Parts subsection of this site:

M-Block 351M/400 Parts Reference

 

That's good to know!

 

Also, car blocks will not have the block off bolt for the front dipstick hole. You will have to block this off if you plan to use the motor with a rear sump oil pan.

Chris is correct on the reinforced main bearing walls on the truck blocks, but the 78-79 D8AE car blocks also received the reinforced main bearing walls as well.
