Camshaft Kung-fu. The force is strong in this one...

Nice, I'm with you strokerscamp, but this doesn't contribute or challenge any of the rubbish I posted. My point again is you can't just haphazardly select a cam and you need to build the motor first to get the numbers THEN you'll know what sort of numbers you'll need for your cam. I already have a build plan laid out to a minor degree and know what I'm aiming for; I also posted reasons for my selection of parts, material and combinations. I'm trying to get a clear idea of how one performs such feat of finding the right cam. Because after reading an article in one of my books let me quote it roughly...

"We built an engine and found the perfect cam for it then proceeded to call up 4 different cam companies and gave them our engine specs, they gave us 4 different grinds and none were anywhere near the grind we had that was optimal for our engine, a few months later we called up the same companies and got different tech guys and again got 4 completely different grinds than they previously suggested, this time it's still far off from the optimal grind we have done."

It's basically telling me these company techs do not know what's good. It would have helped if names were included, but doing that as an author of a car building book can catch you serious flak, the point remained valid though. I also agree with those big budget "home budget" type builds. I've read a quite few, what they won't tell you is the timing and a lot of specific information regarding the build to make it work. They show you how to put it together, tell you the parts and brag about little things but... never do you seem to get the information you NEED. I even went as far as emailing a couple different builds to try to get this information, it's been 3 months.

So strokerscamp, is anything I said, assumed, or think downright incorrect? I'm really hoping someone will tell me if I got it backwards so I can learn, granted I have books that I'm reading and am still reading them.

Side note: power accessories and vacuum; I looked into this before and found alternate ways to run the power brakes and steering. Stuff like hydroboost. This was a day and age ago, so I don't remember much information but at least I know there's alternative ways to get the power accessories without loss of vacuum from the engine itself.
one thing that i do agree with here is not to buy a cam from a salesperson from one of the big companies.ive had the same problems with different "techs"not suggesting the same grind for a given application.and when i did follow a suggestion from comp i was very unhappy with the result.these days if i have questions i turn to people with lots of hands on knowlege for the answer.or i have had very good results with the independent cam grinders like schneider racing cams and crower.id be very interested to know how close their suggestions are to your "optimum theoretical grind."
 
The 380 cube motor we run has 6.00 rods 8.900 deck and short stroke. 8.61 161 MPH. Now i'm confused.
