The m1 intake is just mopar performances name for there high performance intakes.There are m1 big block,small block, hemi, etc.intakes called m1's, but no a 440 intake won't fit a new hemi.I've got the part # of the hemi m1,but its not avalible yet,you can only get it on the crate engines right now.I'm sure edelbrock and others will have some good intakes soon.Ron
