Re: [Chevelle-List] question: power steering pumps & 327/275 horse motors?

Paul:
the "camel hump" heads will show same number for both low and performance heads. The early 1967 327 and 350 took a #3884520 and was available with 1.94/1.50 valves up to 300 HP. The 2.02/1.60 valves were used with the 325 and 350 HP motors. in late 1967 they used a #3917291. The same thing happened then. same part number for heat / different size valves for HP. The "camel hump" is just a casting symbol.
