the '68 340 speed was cam was 114 LSA. I haven't heard anybody say the engine was a dog. Its foolish to look at one number without considering all the other cam and engine specs.
It wasn’t a performance cam either. Using one example is foolish.
Anyone that thinks when making power that LSA doesn’t matter just doesn’t get it.
Another poor example is looking at engines that are running high rpm with max compression and considering that LSA. Some use a very wide LSA to get the top of the piston with less valve notches.
The argument that it’s not LSA that matters but the events only look at one side of the equation. It is the cumulative of the events. Moving the events changes the LSA and changing the LSA changes the events.
Compression ratio, effective compression ratio, rod to stroke ratio and where you want to make peak torque has a major impact on LSA and ICL.
