Slightly off track but i'm about to buy an engine masters 470 from 2003 built by Tom Nelson, i have spoken briefly with him over facebook but can't find any solid motor info on the web. He said PHR did an article titled " A slice of wedge " but i can't find any info anywhere. Can anyone tell me more about this engine, it has since had the 383/13 heads taken off and swapped for mildly cleaned up 440-1's, comp is lower and i suspect the cam is smaller.
