I am loosely guessing here that 10s in the 1/8 is like 15s in the 1/4...which is probably where a 318 in a B body would be with a stock cam and 2 bbl, I'd say 15:70s and I am guessing from having owned a 69 Coronet 500 with a 318 2 bbl.
I suppose my point is, UTG will dock around and Bottle rocket it will be good entertainment for those not in the know, but he'll end up performing about the same as the 318 did when new/stock in the early 70s. He'd have to dump a boatload of $$$ in it to get anything more out of it, and he's about low buck fun so yeah...
