My 331 Stroker, built by Keith Craft, has AFR 165 heads, Edelbrock RPM Air Gap intake, Quick Fuel Tech carb, Trick Flow Stage II cam, put out 436 HP at 6000 rpm, on the dyno stand at Keith Craft, and 326 RWHP at 6000 rpm, when I had the car on a chassis dyno tuner in Fort Lauderdale, Fl. (and it was still pulling - the tuner said "I'd take her to 6500 no problem"). Plugs are NGK BKR6E. Using 93 Octane Amoco Super Premium, and very hot, humid south Florida air!!! RD
