Stroking a 301

anything over 1/2 inch I would go with custom rods.Even at 1/2 you have to grind into the block and cam shaft.A chevy 283 piston and stroking to slightly under 1/2 inch with stock rods makes a pretty nice low buck engine.Depends on how much you want to spend.
 
Looking into building one of these engines myself how far can you stroke one with a custum Rod? and What is the max bore you can get into them?
 
I built a 301 last spring and stroked it to 5" exactly. Used stock rods and mopar pistons that were 3.91". Came out to 361 cubes. We had to do quite a bit of grinding in the block, on the cam, and even a little on the rods themselves, but she cleared and ran great.
