My 1970 challenger T/A was just restored inclusive of a complete engine overhaul.Carbs were restored and dist. was replaced with a factory electronic with the orange box. The cam that was installed was a comp cam XE-268H-10, stock forged pistons with a true (so i am told) 10.5 compression ratio. My concern is, what should the vaccuum read at idle. My engine is reading 10 pounds. Car has twenty miles on the engine.
Thanks in advance.
