Scotty,
I have a 1982 Ford E350 Born Free Motorhome. You recurved the distributor, and offered advice about MPG mods. I added an Edelbrock 1411 carb and Performer Intake, upgraded spark plug wires, used Iridium plugs and redid the exhaust to full3" in and out of highflow muffler. At 55 mph (GPS actual) and on the cruise control running around the LA basin on the freeways, I'm getting 10.5 mpg at 2750 rpm measured by aftermarket tach. This has a C6 transmission, gearvendors overdrive and a 4.56 rear with 8.75-16.5 tires and the running weight is 11,000 pounds. I'm now going to chang out the cam timing set with a Cloyes dualroller set. My question is: how much timing advance can I add to this engine without damage the valves or reducing mileage. I intend to at least advance 4 degrees, but the timing set will permit up to 8 degrees advanced in 2 degree increments.
Thanks for the help,
Frank Grunthaner
