317

I have a 317 kit in my Blue 300 , it is a 300 jug bored to accept a 350 sleeve and piston

So my 317 was bored to .025 over stock , so what it going be now , maybe 320-322 ?

I did forget the " .0 " , thanks for straightening that out for me , you are so right , .025 over is what I meant , so 322 is the answer ----so .050 would be about 327 , which is a cool number for an engine size , a 327 mouse , hope I don't see that day soon , I know you don't care much for the 317, Mac', I might be starting to agree with you , seems I may be in the process learning something I was told recently , that the 300 jug is bored so thin from cramming the 350 sleeve into it , that when the cold water hits the engine and causes rapid cooling that it shortens the life
