NOT the usual cam advice...
It was right there and went in straight up.
Well if it went in straight up, then it's in at 110.... cuz it's a 110 cam, and that blows the forum info out of the water as it pertains to your engine. In your case tho, straight up is not at split-overlap, which, according to the spec I have, would be 106. How do I get that? Easy, start with finding the overlap; you add the durations together, then divide by two; then subtract twice the LSA. So;
(250+264)/2 less (110x2)=37* overlap.
Next take half the overlap from half the intake duration and that spits out your install for split-overlap. So;
(250/2) less (37/2) =106.5, and I always give the half degree back to the exhaust, so 106 it is. This is as close to split overlap as you are likely to get.
These formulas are common to all camworks.
Straight up makes the ICL(Intake CenterLine)= LSA(Lobe Center Angle, don't ask me why it's not Senter,IDK. Up here we call it LDA(Lobe Displacement Angle), so 110=110, which is zero advance/zero retard. . Straight up like this will give you a good compromise for pumpgas and cylinder pressure, so If it was mine, I would just do a compression test and if that turns out good, and even then I would leave that alone. With 2.76s those 4 degrees to get to 106 are not worth chasing.At least not to me....... unless the front of the engine was coming off anyway, and I had room for the additional 5psi cylinder pressure. Well, then, it's free for the taking.....
OK back to the previous post.
