I had it made as a duplicate of the 440 A-134 hi-po specs, true 2-stage springs, a true street performance curve: Less than 4 deg. mechanical adv. below 650 RPM (for cranking) approx. 8 deg. at 950 (fast idle) Approx 13 deg. at 2500 (HP) Vacuum: near-zero at 10" vac, then 9-10 deg @ 15" (fuel economy / no oil dilution) Note that these numbers are all DISTRIBUTOR degrees, double for crankshaft degrees. For most setups you'd want to run initial around 8 crank degrees BTDC. Feel free, of course, to rework the advance curve to fit special applications (crazy hot cam, etc.) Will NOT fit B-engine (i.e., 383-400-361 CID), check my store for the correct distributor for those engines. Ready to drop in and plug into any Chrysler electronic ignition system! Will also work with MSD units. Need wiring, ECU, etc? Check my store for a complete upgrade kit with this same distributor. Buyer to add low-cost S&H per calculator (see tab above); shipped worldwide. |
