Hy; guys have an 502 gen. 6 engine it is factory roller cam it has a fine chain single roller i want to swap to an double roller chain. where can buy this chain? and aftermarket timing cover because i thing i have to change too.thanks Angel

You can get one from http://www.sdpc2000.com/
Thats where i got mine at, and for the timing cover just get one from a GEN V Bigblock and drill and tap the extra holes in the frot of the block since u only got 6 holes and the GEN V has more.
