Re: Help with GM cam timing events?specs,
On the 24502611 @.050 intake duration is 211 with .511 lift and exhaust duration is 230 with .540 lift. It has a lobe sep angle of 110 degrees. I believe this is a gen6 roller cam

Re: Help with GM cam timing events?specs,
They are both Gen VI roller cams.
What engine are you planning to run one in?
I have run them both in my 454 with oval port heads, not much difference between the two.
I guess the HO cam is designed more for the rectangular port heads

Re: Help with GM cam timing events?specs,
Hey rmbuilder,
Can you break down the ZZ502 cam like that for us?
I'd like to plug it into desk to dyno.
Thanks
