Getting worried-----
You are right, some of the stuff I do not know. I can tell you this, The heads are the stock 273 closed chamber heads with stock valves, new and set up to the lunati cam specs with seat pressure, open pressure and installed height using comp dual valve springs. Lunati cam and matched lunati lifters. Heads machined to straighten at .010 off with new seats and guides installed, I do not know the head chamber CC. I am using the Egge pistons 10.5:1 at
.040 over with Mr Gasket 11216 .028 compressed thickness. Stock 273 shaft adjustable rockers with 340 TA pushrods for the hydraulic lifters by Comp. I have no idea what the static or dynamic CR will be but maybe you can divine something close from the attached information. It is not too late to change the cam with something having more duration but up to now I did not think it was neccessary. Please understand, I appreciate all the advice and help and am not trying to blow anyone off. I asked for the advice. If this is a bad combination I can change it, it is not too late. BTW, I am the guy with four (count em) four master cylinders so a wrong cam choice would not me a new experience to me. I just got to reading some of the cam/timing problem threads on here and got to thinking about my own build. Thanks for asking, if I can give more information I will be happy to but this is about all I can tell you until I can run a compression reading on the engine.
