I read recently that the 1953 (and presumably 1954) 261 cam was used in the Corvette 235s to improve performance.

I would query if the 1955-1962 Pontiac 'Astro-Six' 261 car engine derivative of the 261 'Jobmaster Six' truck engine had higher lift lobes? The car engine with its higher CR produced up to 152 bhp depending on year, which compares with from memory 135 in the truck engine.
