The cam already in engine...214 at .050 and 456 lift. One is a new msd street fire and the other hei is good I know runs perfect..been carrying as a spare...fires right up and idles well..its mid range and low on power almost like a wire is off...but not quite. Really does not smoke. Throttle response is good...fuel pump has 5 pounds of pressure. So you tell me?  |
Sounds mechanical:
That vacuum is quite low like a tired motor. Did vacuum gauge needle bounce or move while truck was running?
Do a leak down test to rule out rings seats, etc on those cycls. The autolite tells me that cylinder has had issues for a while and its not carb related.
Anything else is purely speculation and the lack of wanting to do any diagnosing.
