Cam is Howards Solid Roller - 257/267@050 .640/.645 .022 lash hot
Below 32 and I lose a mph.. above 32 and it gains nothing. 32-34 is no difference except the starter doesn't like it, that extra 2degrees is guess is it's limit.
With the 10degree bushing and the lightest springs, it mph'd 117.6. Only change was the front shocks and locked the timing at 32, 118.6 on pretty much all passes not including the aircleaner pass. low and mid do seem to run MUCH smoother with the distributor locked out.
