Or the reverse? LOL.
First thing would be to tune it.
If its a stock rebuild with overboring, you can start with the stock specs and tweak from there. Might need to experiment with timing a bit since that's obviously not stock.
If you can't find a decent set of points and condensor, contact FABO member Halifaxhop.

Nonsense. It was one of the two factory high performance engine options for Barracuda

That's kinda what I was thinking. When i first got my 67 383 running after it had sat for 15 years I drove it around the block and was underwhelmed. First thing I did was buy a timing light and set it to 12* and after that it puts you back in your seat and will spin the dinky tires in 2nd gear with ease.
