Hello Guys, I read a thread somewhere that indicated covering the pin with the locking plate would prevent it from falling out (if it ever got loose) and causing damage to the timing chain and gears. Why is there a hole for the pin in the locking plate anyway. My new Comp Cam timing gear set came with a plate with only the three bolt holes in it. I am building up a 383 with Procomp heads, thumper retro roller cam, timing gears, and magnum roller rockers.
Yer tape measures reed funny.....ain't NO way them thing 20" diameter or so.....
