I have a 1965 Monza with a 140/4 speed. The engine has a .443 lift/280 duration cam, .060" over Keith Black pistons, Wolf Enterprises performance carbs, 8mm plug wires. I had a Crane XL700 breakerless system but was not happy with it and returned to points. This is strictly a street car. What are the right plugs for this engine? Steve Schwartz 140 VAIR
