Hey Scott,
Welcome to NHRA I know you are or were a NMRA guy for quite awhile. If you click on the NHRA Competition link in the header above and then go to stock car classification guide then go to Ford 2010, Mustang it will give you the NHRA accepted options for that year, make and model. The 352 and the 428 options for this year were paper motors that came in the 2010 Cobra Jets only. These are pushrod motors the 352 is a 302 based engine and the 428 is a 351 based engine. In the same area were you find the stock car classification guide is also the engine blueprint/spec guide. Do the same there Ford, 2010 and it will list part numbers and specs for the engine of your choice. Hope that helps.
