MJ, I THINKS CLOIS MAY HAVE IT RIGHT. HOWEVER, TIMING 2 DEGREES TOO ADVANCED OR RETARTED CAN CAUSE THE SAME THING. HAVE HAD IT HAPPEN. WHOS VALVE SPRINGS ARE YOU USING? HOW DO YOU LIKE THE CAM? AM BUILDING THE SAME COMBO OF TRANS AND REAR GEARS AND WITH A 060+ 390 AND AM THINKING OF USING THAT CAM. HOW DOES IT WORK WITH THAT COMBO. HOW IS THE IDLE.? GOOD LUCK AND THANKS!
