My questions are, if running a narrow lsa, the increased overlap should help top-end horsepower and decrease low-rpm torque/cranking compression because it would bleed off cylinder pressure at lower rpms right?
If running a wider lsa, you would have less overlap and therefore more low-rpm torque. But they say a wider lsa produces more top end power?
I'm sure thats the way it is but I'm just confused on how it works.
Any comments are greatly appreciated.
