LSA/LDA vs power production ??
You know, when I see the clarity & technical mastery displayed in these responses, I realize the error of my ways. I just cant hope to compete here, so from now on, I'll just listen & learn, and leave the tech questions to the real experts on this board.
Oooooo, sarcasm is running rampant! lol. Easy buddy, Moper asked that we all be kind and I don't see why you're so upset about this. It's just a tech discussion on the internet for pete's sake. :thumrigh:
Now, the following has always been my understanding of narrow LCA's vs. wide LCA's:
Narrow LCA
Increases cylinder pressure
Has a higher tendency to detonate with high compression and pump gas
Pulls less vacuum at idle
Idle quality is worse for a given duration
Best for a low compression stock engine
Does not work well with electronic fuel injection
More low end torque
Peakier torque delivery
Wide LCA
Reduces cylinder pressure
Has less tendency to detonate with high compression and pump gas
Pulls more vacuum at idle
Idle quality is better for given duration
Better for a high compression, big valve/port build
Can work well with electronic fuel injection
Less low end torque
Broader torque delivery and allows a higher rpm potential IF the engine is built for it.
With this said, please read this next article by David Vizard. He brings some points up that I haven't thought of and adds more fuel to the fire.

Comments george? Please don't be shy. :) We're all adults here and there's no reason why we can't have a contructive discussion and all learn something new.
