spark knock?
I need to pick all of your brains. I have 78 460 block, d3ve heads, speed pro hyperutectic pistons(part# sl h582cp30) and lunati voodoo 6061 cam. Ok here is the problem, i can not seem to get the timing set so it it wont spark knock. If somebody can please give me some ideas to try it would be appreciated.

I had this problem when I rejuvenated my engine back in '08.
Found I was getting a total of 56* advance.
Had to purchase a Crane Cams 99601-1 adjustable vacuum advance and recurve my distributor.

They are out of business, but I find it on Amazon. (the picture is wrong but the P/N is right)
Amazon.com: Crane 99601-1 Adjustable Vacuum Advance Kit: Automotive
Be sure to ask the seller if it is INDEED the one for a Ford DSII dizzzy.

Another thing to think of, is the EGR hooked up???
