429 Fuel Pump Eccentric
#1
Well its been a while since Ive had a ford engine apart so I have a question. I know most V8 fuel pump eccentrics that bolt to the upper Timing sprocket are 2 piece. My question is: Is the outer part of the eccdentric supposed to spin free or not?

1973 Mach 1 429 cu. in. H.P. TBD, C6 Reverse Manual Valve with 3500 Stall Tranny, 9" rear 3.90 PosiTrac
