Inliners International Forums General Discussion MOPAR max substained RPM for highway driving

I see no problem running in the 2700 to 2900 RPM range. The horse power on these engines is rated at 3600 RPM and 85% of that is 3060 RPM. I have concluded that I was running way too much ignition advance with the 10 degrees initial at 500 RPM. The book calls for 0 degrees at TC. I timed it like I do my 235 I/6 Chevorlet. At 3300 RPM it could have been firing 50 degrees before TC if both centrifugal and vacuum advances were at their maxium. The centrifugal and vacuum advances more on MOPAR cars than it does on old Chevrolets.
