Yes, the 301 has a 4" bore and a 4" stroke- - - - -with longer connecting rods and whatever 4" bore piston has the right compression height (Chevy, Ford, MOPAR, etc.) the 301 stroker shaft could go to 4 3/8" or maybe a little more. A 4 3/8" stroke and a 60 thousandths overbore on a 301 would give 340 cubic inches.
