So time for a bit of fun and revisit the guesstimates.
I’m calling it 568hp @ 6500rpm and 532ft/4900rpm from a run with 975cfm carb that wasn’t influenced by multiple runs (the 571hp/538ft/lb run)
Sorry bob, maybe lack of sbc faith clouded your estimate
Now you need to back it up at the track.
How much the HQ weigh?
Good job all round
They guys (Allan and John) told me they they installed the dyno back in about 2007/8 to do their own development work and verify what they build. Back when they done the extensions. They don't advertise as a service or use it to turn a profit.
Happy dyno? Time and track will tell as you say. I didn't have my heart set on a number so it won't be broken if it didn't happen. From the outset the primary goal was to be able to drive to Calder or Heathcote, run 11 flat and drive home with these old antiquated Twisted wedge heads. I like a challenge.
Thanks bob and I'm sure we will catch up one day.
