Bob, somebody mentioned setting the valve lash to specs - do that first Overheating / hot running engine = over advanced timing (hence all of the pinging), lean fuel mixture - low coolant not withstanding Does the dist still have points? If so, I would really recommend the Crane XR-700 or 3000 electronic ign setup. Vs. the pertronix. You can set the dwell angle to whatever you like with the Crane product. I used to use the Allison elect ign (now Crane) on my 71'. I set the dwell to 48 degrees, and simply set the timing using the "retard until it just start to ping, and then back it off a hair" method. My 71 with an L28, w/stock SU's would scream all the way up to 7600RPM. There are allot mechanical variables to consider when setting the timing, i.e. camshaft gear position, compression of engine, valve lash etc. So using an inductive timing light is accurate, but I usually found it necessary to either advance or retard an engine after make a test run or two. Happy motoring!!

it's the high-capacity version of the Fram PHA8 filter which fits L-series blocks - Costs 9-12 bucks. It's constructed much differently than their standard Extra Gaurd 4 buck filter.
