Good Cam Choice?

Does it matter that my self-learning is disabled since I have a professional tuner? Can a good tuner tune around narrow LSA? Or is it not worth the extra you get from an optimal LSA? Thanks in advance.

In the past, present and current systems I can not answer on, the tighter LSA and the computer do not mix very well as the tighter overlap seems to not work very well with the computer. Perhaps confusing it? IDK.

I’d say if you can tune it (or somebody else) the narrower LSA is the way to go for more low end torque and power everywhere. It would be worth it IMO, if it can be done.

PRH,
Post #13. Richard Holdener tested three cams in an LS engine, EFI, identical for LSA. Purpose of the test was to see what changing LSA did. From memory, LSAs were 108, 112 & 116.
The 108 cam made more average hp & tq.

Past experiences may have jaded the idea. (?)

What system did Rich use. I did see the video. I don’t remember the system. IIRC, it’s a Holley, but what exact model it is I do not know.

I do remember in the past people having a hard time with the low LSA & there FI. I have not kept up.
