I got the Edelbrock Performer cam/ lifters and Cloyes timing chain 9-35008X9. I went with the 3 piece billet USA made true roller chain. One issue the pin for the cam sticks out about 1/8" , I see cutting this down so it doesn't protrude and push against the fuel pump cam. Second the cam gear appears to be 180 out . As I set TDC No1 and No6 piston, Rotor at No1 , then removed the intake and all the way to to the cam,the original timing chain marks lined up as should . With out decreeing the cam I can see the original cam pin was to the top, when a dry run install on the side by side , the timing Mary is 180 out, Also do I go 2, 4 degrees advance on the lower gear, which rotates the crank clockwise looking at it,? This is in a 1972 Ford F-250, putting the Performer cam/lifters, Edelbrock Streetmaster intake, 1405 / 600cfm carb, Flowtech headers, Pertonixs II distributor and coil. Any advice or guidance would be appreciated .[ima
