Do any charts like this exist for the current camshaft offerings? I did the calculations and made my own charts for the really old camshafts. It took days making all of those calculations.
I am helping a buddy with an old school 383 SBC and a flat tappet with an IVC point of 60 degrees would yield a DCR of 8.17 at sea level.
An ISKY 264 Mega is one such choice.
What do you mean by "Current Offerings". Are you referring to OEM stock camshafts? Probably not unless someone measured them.
As for any aftermarket cam? That can be provided by the MFG. Most times just by looking up the grind on their website.
Example, the CC-306 that people love to shove in LT1s. But really you can look up any CompCam specs this way. Same for Lunati and others. If its not listed, call the MFG and if they can't provide it, they don't deserve your money. http://www.compcams.com/Company/CC/c...csid=1103&sb=2
The IVC, IVO, EVC, EVO are all listed, along with gross and at .050" lift durations. LSA, LCA...etc.
Thanks. I was talking about current offerings from the major brands; Crane, Crower, Lunati, CompCams, ISKY, etc.
Here are my charts for the streetable old flat tappet camshafts.

However, I do remember calling and asking for the event timing and they gave me the #'s over the phone.
Basically, the cam MFG should be able to give these #'s to you. If not, they are being shady and you should not do business with them.
When you buy a cam, it should come with a sheet of paper referred to as the Cam Card. This has all the valve events, lift, duration, lobe sep, lobe center...etc. Everything.
