Patrick's 254/264 is the 'bulldog cam' (254/264 Delta Cam Shafts Grind) and works great as a street engine with a (bored) 261, 3.55 rear, 3 speed trans without overdrive and dual 216 carbs and headers. Tire diameter variation to taste.
For a 235, even if bored 40, its a lot of cam with peak torque curve starting around 3000 rpm.
Add a 3.08 rear and instead of 'get up and go power' you have 'slow-motion'.
Even a 261 would lug with that cam and rear ratio at lower rpm.
The bulldog cam in a 235 turns it into a racer needing easier breathing and 3.73 or 4.11 rear with 4 or 5 speed trans.
