Thanks for the comments on how LSA is calculated. Now that I understand intake/exhaust Lobe Center design provides the "average" for the LSA, I need to some more thoughts/feedback. Given that my 360 combo has the stock compression height .060 forged pistons (= lower compression), would I want a low degree intake lobe center (106/107?) and a higher exhaust lobe center (112/114) to build more initial cylinder pressure. Example, I see these 2 Oregon Cam regrinds that utilize these different LCs:
1369: 218/224 (.050), LC: 106 (Intake), 114 (Exhaust), Lift (1.5) .462(I)/.470(E)
1176: 230/236 (.050), LC: 106 (Intake), 114 (Exhaust), Lift (1.5) .488(I)/.491(E)
I'm leaning towards the 1176 for my combination: Duster, 360 - 340 X-heads, single plane, single plane intake, 750 DP, 3k stall, 727, 4.11 gears (8 3/4). I've always been of the opinion; I'd like a little more cam than not enough.
