550 out of a 289? At 1.9 hp/ci, that seems a little optimistic....

900 hp out of a 358 NASCAR engine (2.51 hp/ci)(this comes directly from one of the NASCAR top teams crew member that I have been knowing since he was a kid that grew up down the street from me) is the norm right now, so 550 out of a 289 is certainly doable.........and a lot of those "289's" come from North Carolina/Charlotte shops.......
The top tier Vintage racers are racing with cubic dollars and have been for a long time.......
