How many cubic inches is a rebuilt 305, if it has been bored 30 over?

310, great, thanks. Looks like you speak from experience.
Yep, I rebuilt it last year. Figured if it ran great for 19 years and 212,000 miles, must not be too bad of a motor. :-) Looking forward to the next 20 years!

He didn't say he bored it to get more HP.
212k miles - hmmm, if you want to get some real longevity out of it this time, use synthetic oil (a "real" synthetic).

The first 500 miles were on Castrol conventional oil, to seat the rings, then, I switched to Mobil 1 10/40 and intend to use synthetic from now on. In addition, I might add an additive like Tufoil or Slick 50 too, to help reduce friction.

No!!! No Slick 50! Do not add PTFE to the oil.
You really don't need an additive with M1 oil. But if you must, the Valvoline Synpower oil treatment is loaded moly and it's good stuff.

The only engine lubricant manufacturers that recommend an additive are the additive manufacturers. Most reputable engine oil manufacturers offer a warranty with their product, which is voided if you use an additive.
Mobil 1 10W-30 would be a better choice. And, just to make sure the message gets through, don't add something from another bottle to it.
I'd 2nd the AMSOIL recommendation, but then my bias may show (Series 3000 HDD 5W-30 is what I'm running).
