I'm installing a new cam. lifter and tinming chain on a '70 383. I've got it appart and doing the cleaning and painting thing. My question is, when installing the new timing chain the instructions that came with the set (from Mancincis) says the dot on the cam gear is at 6:00 and the crank gear is at 12:00 and a friend has also told me that. The counter guy at Mancinis says the dots on both gears should be at 12:00 and I've read that in an archive posting. Just looking for clairification.

Also, when I disassembled everything, the #1 piston was up, the rotor was poiting at #1 and the dots were in the 6 & 12 positions. Thanks
