366 has same main journal size as other BBC don't know of many ever doing anything much with them,had a friend ran them years ago in Super stock 4wd pulling,they had 366'' limit,they made the rules don't guess they thought of anyone building 366'' BBC, he dominated it.
About all we have ever done besides build them back stock, is use the cranks,in 396,427's and use the rods for stock rebuilds.
366 wouldn't be good for any kind of budget build,by the time you had custom pistons made that would be more than the difference in $ of 454/427 block,could build bigger for same or less money.

HP,I like your build.

1.What drew you to this style head?
I was running out of 781 and 049 castings in my engine building buisiness.

2.Did you have to replace the exhaust seats?
No, on muscle car builds I do not replace seats, but I'am a fanatic on round strait properly sized and finished valve guides which lets me make a very concentric seat with a extremely nice contact patch that transfers heat good due to the valve setting down on the seat perfect every time. Tow applications get a 1.750 CHE exhaust seat.

3.How much do you think you increased the volume when finished?
I don't know I didn't check it, I machined, built, dyno tested, installed it in 7 days.

4. Did you have to fill the intake manifold to match, or was it close?
No, I smoothed the plenum divider, the intake is not the cork.

5. I have built tow engines close to this, this engine would be good in my dualie, except the 9.3 comp would worry me along with the 1.880 exhaust valve size. I will put a link up to my 489 tow build along with a picture.

6. Last is that Scott Welborns old car?
Yes, I bought it from Dale Hulquist the BSer, when it arrived I realized it would need a total rebuild from front to back, and thats what it got.
