Take it to a shop

shops suck but if you look at the top of the piston there should be some numbers look for some thing like 66.25 to 68.25 if its been bored like you said 68.25 is as big as you can go without going big bore. or you could take the jug to a shop and they should measure it for free.

start with a 280ish main and do a plug chop and go from there
