Re: D16z6 Camshaft, best cam for the $$$? Regrind or new?
 

I have a Comp 59300 in my ZC block, Z6 head motor. Stock springs. I run it to 7500rpm all the time, no problems. :-\

He told me what they would do is increase intake duration and delete any overlap, it wouldnt lift any higher or anything tho which I understand, but how can they increase duration on the intake?

Re: D16z6 Camshaft, best cam for the $$$? Regrind or new?
 

the only way to increase duration without increasing lift is to add material.

now i cant wait to take a look at the cam in my d15b. i plan to do a similare z6 build with the same hp goal. maybe i will use my d15b cam in it since i already have it

well its at delta, they got it a coupple days ago, as soon as I get it back I will be able to finsish assembling my head and throw it together, I may even feel the sweet nector of a 300+whp honda within the next week.

from what i understand, they grind the base-circle smaller, that's how you get a larger lift.
But if you knock the tops of the lobes off too, you get no increase in lift (differential stays the same) but you can play with duration and overlap some.

That's obviously not the exact science of it, but you get the idea. Or am I in left feild?

Re: D16z6 Camshaft, best cam for the $$$? Regrind or new?
 

that makes sence, but you cant go very far cause of the angle that the rocker arms would be to the cam would start to cause problems

yup, limitations and drawbacks of regrinds
