Hello, My son and I are building a 74 duster and have decided to put a 360 magnum in it with an OD trans. Paint is done and car is going back together except for the old 318. I have decided that the magnum engine is what we want to do. I have the chance to buy a 360 magnum and I want to make sure it realy is a 360 is there anyone that can tell me how to make sure it is a 360 whitout having to take it apart to measure the bore dia. Please help. thnaks,

 

Welcome to DF arron! I am going to move this over to the Dart Demon and Duster section for better input! Good luck!

If this doesnt help let me know! Well move to another avenue

 

It should be casted on the drivers side of the block

 

Thanks to everyone who replied to my post. I have identified the engie and it will be purchased.

 

let us know how the swap is going! You might have to use a three speed auto, I dont think the 505 or 518 trans will fit under the stock floor pan. some modification might be required
