Yep, sure would be fun alright. I presently am restoring an 73 Hornet Hatchback (first year of the hatchback) with the X package on it. As sitting right now, it has a 304 in it with the manual 3 speed on the floor. Someday in the next couple of years I want to install the 401 with the four speed. Boy what a screamer it would be and blow same year Mustangs and Camaro's off the road (or the least fool them).
