Best down to earth info,seen in a damn long time(on Magnums). Thank you ,Ramm. FWIW,what is the intake runner cc out to. I have heard of smaller than stock Magnum 153 c.c. replacements?...
I wondered this as well so I found some time to check 2 ports. An untouched port came in at exactly 153cc's. The port I had been working with came in at a whopping 154cc's. J.Rob
