Comp cams xe268h for 318

If it was mine, I would put it all back together as a stocker .
First; put a stinking 2800TC in her. That is step #1. That will pump something like 60/80ftlbs more into the tires,on the start line and for quite a ways out; and no cam on your list is gonna touch that.All the other changes together will not touch that. It takes supercharging to touch that increase on the start-line.
Next is gears: and 3.55s over 2.76s will multiply your starting-line torque by another 28.6%, so now plus maybe 100ftlbs into the tires, getting close to plus 60%, over what you currently have.And with just two simple changes.
Third is the 4bbl carb, which adds nothing on the start-line with 2.76s and the factory 1800ish TC, but together with the first two, and the plus 28.6% TM, now that she can break traction, it will.

Oh wait, I already did that, with fantastic results.

The cam with no compression increase,just shifts the power to a new higher rpm, usually with a loss at the bottom. And the bigger the disparity between advertised and the .050spec, the worse it gets. That would be dead last on my to-do list. But with the 2800 already in there,now, the bottom-end is no longer an issue.
If I still had the desire to upcam (which I didn't), I would get me a fast rate of lift hydraulic lifter cam/kit,anti-pump-ups, plenty of lift, and on a 108 or less LSA. Say about [email protected]. Then I would pump up the compression ratio as high as I dare, to run 87/91 gas, on whatever the advertised spec dictated.
That's how I would do it.
This way, every change brings instant performance increases, and sets the combo up for the next change.
>One thing I can guarantee you is that slamming a cam in there with no other changes, is not gonna make you smile,until the Rs are well past 3000 rpm, probably closer to 3800. And with 2.76s that will be around 38mph. Been there/done that. Too.
>Another thing I can guarantee you with the factory compression ratio,is that with a 1800TC and 2.76s, a 268/110 cam will make a dog combo.This is because the dynamic CR will be miserably low, and therefore make pathetic cylinder pressure; Probably under 120psi.
>And a third is that a 262/114 will also be a dog combo,because it will have almost the exact same ICA, and therefore the same miserable 120 psi; which is DOWN !, from the 130 it might be making now; so of course it will be less powerful at low rpm. AND, the 4bbl will do nothing at zero mph to alleviate this:zippo, nada, nyet, nuusct. Oh wait, if you have a TQ or a QJ, those carbs will make a great moaning sound if you loosen up the secondary air door, but you will have to wait for the engine to recover from the bog. But at least the moan will give you the impression of power,lol.
Anyway; there's my 2 cents.
I've tuned a lotta teeners in my years, and the best results are always in the above order.
Well; there was this one hi-compression/small cam/2bbl, combo,that worked pretty good with a 2400TC , 3.23s,and an A904 trans . Oh wait; that was a 4.04 bore,lol, one of my all-time favorites.
