114+2 cam timing question?? When setting cam timing on a custom cam ground on a 114+2......
We got a adj. timing set so on the crank gear, we set the gear on the a2 (advanced 2*) correct? As opposed to the stock placement?
And why do cam guys grind them that way? If we set it up for just the 114 would it even work or will you trash the vavletrain? Why not just grind it on a 116.
These are the cam specs:
224/230 dur.
567/578 lift
on a 114+2 lsa

ok, i know how to do a cam, i did it in a few cars but new to the whole 114+x design so bare with me please. SO then sounds like your saying.....
Install the timing chain dot-to-dot (12/6) like normal and they actually ground the cam 2* off center?
And we only have the cam card and no instructions or guide. He bought it used off a member here. So sorry for asking, were not stupid, just new.

damn dude you just don't get it.
they put the advance into it so the average joe can just install and go
if you have so much experience you should know this
I am over and out of this thread

I have mechanical experiance but i said i was still new to the tech part of it and still learing that aspect of it all. I get everything about the advance and how to install it, the car is already running... But what is the point of it being 2* advanced as opposed to any other cam not being advanced?

a lot of ls1 cams have advance ground into them to bring the peak power range down a little bit to make it more daily driveable, since people tend to go with cams that are too big for their setup. If it was ground straight up many cams would feel like a dog at lower rpms

So advancing the timing makes a big cam streetable, got it. So is that the same idea with a adj. timing set. Like my buddy with a MS4 cam, if he puts his timing +2*, it will have better street manners with a better torque curve on the low end. Basically in a nut shell..

only to an extent, you have to be pretty familiar with what the ground in advance is and what the valve events of that particular cam is. myself, i dont know a whole lot about that sort of thing, so i kind of go by what i read

Well i dont plan on opening up my own shop eaither, lol. But at least i know about how it works any why. I wont hold ya to anything. But it does make sence now. Once you think you it all, more tech. stuff like this comes up. And people wonder why they pay so much money for for a shop that knows what there doing/know vs. some garage mechanic, lol.

I know what lsa means and what not and how it works and what it does. So with this cam being a 114+2, what if we put the crank gear -2*? Would that make his peak power higher then? Or would it even work without the valves hitting the pistons.
