Thanks for the inputs everyone, let's not argue. I left the 110 vs. 114 comparisons up as point of discussion, not to go into the details of why 114 was there in the first place. I was (still am) confused over how overlap (tight LSA) at idle can create an initial higher cranking psi. Case in point, I once had a 406 SBC that had a solid lifter circle track cam with 106 LSA, very detonation prone. I later changed out the cam to a milder hydraulic with 110/112 (long time ago) LSA, shorter duration, nothing else changed. That same motor ran fine on 89 octane unleaded. I guess that's partial evidence that tighter LSA can produce higher initial cranking psi. I don't have any power accessories on this car and it's a weekend only ride, so low vacuum and rowdy idle isn't an issue. Would a 106-108 LSA build up higher cranking pressure for my low compression combo?
