My Street Demon install experience

Initial, this is a mild 340 with J heads and small port Weiand 8007 Action Plus spreadbore. I haven't driven the car much in the last 10 years so I'm gonna run this gas out and do some tuning before I speculate too much. I will report back how it's running. I'd be surprised if it needed larger jets.
Good idea. Dont change anything then.
Maybe get some Lucas octane boost and pour the whole bottle in no matter if theres only 1/8 of a tank.

Cool. Let us know.
