But wait a minute.........
Centerline 101 103 105 107
Peak HP 633.5 633.0 644.6 645.3
Peak TQ 590.6 594.2 594.3 591.9
Average HP 510.1 510.7 512.7 511.9
Average TQ 551.1 551.9 553.3 552.4

So ease of cam centerline adjustments are worth something ?
Now , try a belt driven distributor.
Truth be told , the differences appear to be small.
But the slack jawed pointing I see when I open my hood on cruise night are worth something.
I don't have dyno numbers , and I don't have a time slip yet.
So I will have to be satisfied with those little amusements.
