But no kit that I can find.
The Ford 302 is easier then a Chevy swap because of where the distributor is located.
If the rear axle is a solid rear, or you can live with one, just swap the parts out of a mustang (t-5 and all) and have the drive shaft shortened (if needed at all). At least then it will be easier to mate all the parts.
