I am in desperate search of the timing spec for a '71 Charger 488. I am able to find data on 488's 72 and newer but not for my sled. And I am certain that the spec for a '71 is different. The sled does run and start excellent, however it does not run well at 3/4 throttle+. Thank you for any and all help!

I know this is a very old post but here is some info for you. Your 1971 has the EC50P engine in it. http://www.vintagesnow.com/Polaris_files/1971_polaris_SM.pdf
