Thanks. I always here though, "Is negative less?"

Yes, he will be able to tune his truck with EFILive Flashscan which is what he is getting.

might want to edit it to say more negative = more overlap

No, the higher the negative value would be less overlap. Are you just reading what I wrote wrong? Maybe it wasn't stated clearly. Tell me what makes it more clear to you and I can edit it.

People get confused when you put a negative value for overlap. "How can you have negative overlap?" In other words, there is none @ this part of the lobe.

Like I said, I know you are aware of all of this, so just tell me what makes it more clear and I can restate it.

Sorry, I was misreading it.
You said
The more negative you go, the less overlap you have. So, the 220/220 - 110 cam has 8* more overlap than the 220/220 - 114.
but did the math on the 114 LSA cam first. Brain Fart/Assumption.

I thought you were saying the 114 has more overlap.

It is kinda misleading because neither has overlap. the 114 cam has an 8 degree space between lobes and the 110 has the intake lobe start right when the exhuast lobe ends.

I figured that was what it was. I should of used a 230/230 - 112 vs. a 230/230 - 110 where both have overlap.

Im gonna go ahead and throw in my recommendation even though its futile.
but what the hell Im at work and bored

You can have a low lsa with less duration and make more power and have better drivability, especially with xfi type lobes and the stock heads and intake.

216/222 110/108 .58 lift xfi lobe

216 -.58X'' and a 222* - .58X''... Do you have part numbers or any more specs on these lobes? Where did you find them?

I was under the impression that more overlap meant you would make less peak horse power but your powerband would be bigger. Am I mistaken?
