To me, LSA is just a number used to order the cam grind, but Werby is still 100% right, less overlap gives up power.
To me, on a relatively stock FE, I'd be adding some split to whatever cam put me where I wanted to be, and use LSA to control overlap as required. Although I use both single pattern and dual pattern cams, a CJ almost always likes a bit more exhaust
I am running into the overlap choice decision on a 461 CJ right now, I have lots of room on the build, except for a single thing, power brakes. It is forcing me to go wider than I would normally prefer, but it's a very rare car and adding vacuum pumps or cans to the car is not an option.
I forgot what Brent used, but it was likely a very sharp choice.
The whole spurious argument that got started on Speedtalk over whether valve events should be discussed in terms of overlap or duration/LSA is arguing over semantics, the numbers come out the same., I have zero interest in debating semantics, I'm interested in numbers.
If we want to argue over the semantics, what we should do is go back to describing cams in terms IO, IC, EO, and EC, like they used to do. That would sure narrow down the number of guys posting on cam threads in a hurry.
I promise I am not that guy, and I don't enter those fights....and wasn't my intent, but happy to discuss cams however you want. Heck, I am the guy talking oil ring math on Speedtalk right now and can't get anyone to engage
My only point is that if I give advice, I have to talk valve events and the effects of those events. LSA doesn't let me, I have to back into it. Heck, I am having a hard time managing overlap with a 114 LSA cam causing me fits for the stroker to get it where I want.
So if someone wants to talk cam behavior with me, I have to get to cam events, even if we push it back to LSA when done. However, now it sounds like I am discussing semantics again.
Forums are a tough place, in the end, I really really REALLY don't care about anyone else's semantics, I promise!
In the end, you likely know me well enough from this forum that I don't have any desire to argue with anyone, so I sure won't pick a fight. I am the "love and respect everyone" guy LOL If it sounded any different, I apologize
