422 dyno fail

B3,
And how many cam combinations have HRM tested? Anywhere near the 19,000+ that DV has?
Try getting your facts right before say somebody else's comments are untrue.
DV says this on p. 97 of his BB Chev book:
'If maximising power & tq are the goal, spreading LCA [ LSA ] to improve idle & low speed drivability is a veeeeery counterproductive move. The correct answer is not to spread the LCA, but to go for less duration.'
Also, Richard Holdener recently tested identical cams except for LSA on LS engines. From memory tightest LCA was 108, won overall, & worked fine with the EFI.
