Was that .118/.140 figure measured before or after the heads were milled.045”?
Your old SFT lobe vs a moderately fast SR lobe of the same duration @.050”.......... the SR would only have about .015” more lobe lift at TDC with both installed at 106.
With the new cam installed at 106, what is the lobe lift at TDC?
The roller lobe I was using for comparison would be .154”
Here’s a dumb question......... You’re not trying to degree the new cam and check for clearances with a flat faced lifter, are you?
