Deck HT, CR, CC's, cam dur

here is a site I got from a responce on this site
it is Pontiac CR calc vehicle, I just entered Chev
spec's is all.

For those of you guys who are follow my craziness. The only
issue I am in now is deck height. If I throw in a average which
it should be .025+- and if I play with the cam duration I get my
CR of 9.38:1 and my dynamic CR in the 7.75-area. This is all assuming
a 97cc head, .022 head gasket and a 268 cam duration and if I go
up to 287 duration CR dips slightly and dynamic dips to 7.3 or so.
so from what I am seeing if I can nail the deck height to what is the industry
standard my .040" must be wrong, has to be less than that and go with a Comcam 268, with 107 lobe sep I should be happy.
Thank you

Again, you're trying to "wish" this motor together. If it measures 0.040", then it's 0.040". Motors are put together with cold, hard facts, not wishful thinking. Pull your head out.

CR,calc's etc..

"techinspector1" thanks again.
With all due respect I am not wishing for anything. 30-32 years
ago I threw speed parts together to be loud and bumpy idle and obnoxious knowing zilch, zero.
Today I am just trying to learn to crunch #'s and am trying to make things simple and functional. It is a toy not a daily driver. I just have a few extra bucks after the "x" takes her cut and need a project. Anyway, too much info, this is about motor head junk not counseling sessions.
Maybe I shouldn't do any cam work and just put my milled 063 heads on
with headers, 4bbl carb, leave the stock remanf cam in and call it good. It is already resting in a lite car 2dr 65 Malibu.
