Original flywheel dyno sheet from Danbury is 440 and 475 with no attempts at optimization, just a bolt-together of Joe L's standard 428 build.
I've replaced a boggy Holley with the Speed Demon and run the timing forward a step. While all my dialing in so far has been old-school, I eliminated the bog and it's a lot more responsive. Either the engine was down on power when I got it and I've restored it to original tune, or I've added a bit.
I plan to add some O2 bungs and do a sharper tuning job across the band before a dyno run and tune sometime in the spring.
