IT IS GETTING 12 VOLTS TO THE DISTRIBOTOR,IT SEEMS LIKE THE ENGINE IS NOT ON TOP DEAD CENTER,I ORDERED A TOP DEAD CENTER LOCATER FROM EASTWOOD COMPANY,WHEN I RECIEVE IT I WILL CHECK TO SEE IF THE BALANCER SPUN.

What kind of timing gears/chain did you use? You did line up the correct timing marks when installing them? Some have multiple marks for different cam timing. :-|

THE TIMING SET IS THE DOUBLE ROLLER CLOYES THERE BEST SET,
THEY ARE SET AT 0 NOT 4 DEGREES ADVANCE OR 4 DEGREES RETARD.

I TORE THE ENGINE DOWN AND THE CAM,LIFTERS,CAM GEAR,DISTRIBUTOR GEAR ALL CHEWED UP SENT CAM,LIFTERS,PUSHRODS,ROCKER ARMS TO COMP CAMS THEY ARE GOING TO SEND ME EVERYTHING NEW. I THINK THE COMP 1416-16 ROCKER ARMS AND +150TH LONGER PUSHRODS WIPED EVERYTHING OUT. MARK =D>

sealed power-summit and comp cams have had some problems with their AMC cams as of late. Sealed power cams bend rocker arms (some of them) Summit has had casting flash in the holes allowing oil pressure to build up behind the camshaft pushing the cam forward Comp has done both Its amazing how much money this costs your average AMC'er :(:

The pushrods shouldn't have caused anything as long as the lash was adjusted correctly. I'm running a Crower cam in my 390 with +.100 pushrods and Crane Gold roller rockers. With the roller rockers, the geometry is much better with the longer pushrods than with stock. I'd heard about cams that were cast with the center (#3) journal too wide. It would touch the lifter just behind the journal (#5 exhaust I believe), and force the cam forward. Also make sure that the cam plug at the back of the block isn't in too deep. Hope you get it going. Bob. tufcj
