can anyone give me a breakdown of all the different timing chain and sproket replacement part numbers and interchange info? I have 1963 1/2 ton with a 305 e with a double roller chain. What are the difference between the 305 and 351 and pre 66 and post 66 years. I bought a cloyes c166 chain to go with stock gears and found it to be very tight on crank sproket. Found a dyna gear73031 3 piece set that interchanges with melling 3-170SA that goes on ok and looks the same other than where the hole for the fuel pump eccentric locater pin goes but lines up ok. Orielys listing that chain set for both early and later years but individual parts from early to late are different.
