So how does the regrind work, by making the center smaller, it in reality doesnt actually make the lobes bigger, that is phisically impossible lol but how does making the center smaller improve anyhing

0mg. It makes the cam start farther in so if it gos farther in that makes it longer. Understand?

No offense taken, I was wrong for even opening my mouth, so it's all good. I'm still trying to figure out how these regrinds works. Does anyone have a picture or diagram explaining out it works. All I can find are written explanations, and I still can't see it in my head. Are there areas on the rocker assembly that will allow the whole assembly to sit lower due to the smaller areas on the cam?

The elongated valve screw compensates for the ground lobe. The lobe now lifts more (relatively) than it did.

This is, as far as I understand, how it works.



(Sorry it's so crappy, I made it on Paint.)

The cam starts farther in??? . . . What?
What does that mean?

Accrdwgnguy already explained it properly - "Delta Cams usually just grind the base circle of the cam smaller"
That is how most regrinds are done.





You do realize that the person your replying to (dj_ender) is the creator of this thread right?


How is it that you can do the whole "Omg" about one thing to the thread creator, And yet you also didn't understand something, and no-one gave you that kind of response like "Omg everyone should know that" ?

At least someone like cbscandal actually explained it properly to the OP.

No shit the base circle of the cam smaller so the cam lobe starts farther in

That still makes no sense.
Why are you so upset?

[dj_ender]

Ok, let me see if I got this right. The "base circle" your referring to is the same area of the cam that you use to adjust your valves, correct, or no?

Just because Its so simple and some people just cant understand it

Thank you! I was unable to find something that explained it and showed it. So now, it would seem like I was fairly correct in saying that since they take off material you would have to tighten up the valves and that he had plenty of room left on the tappet screw.

Correct.
The clearance setting can change from the stock (.10/.12) when a regrind is done, and the person who does the regrind will give you the new clearances if required.
