340 cam in a 318

Dan the man said

I have a question about putting a 340 cam in a 318. From what I've found out, the 340 cam has a ivc point of 69* and this brings down the dcr to like 6.63:1 ( 18 psi lower cylinder pressure than a stock 318 cam ). Wouldn't this hurt performance rather than help? I based this on a 1973 318 with a 8.6:1 cr. Did I figure something wrong or have the wrong information?

Dan, as soon as you come here and talk about a 340 cam in a 318, every man and his dog is going to comment how legendary it is. LOL
Now, as I can see, your interested in the way DCR changes with cam timing, and it's effect on performance, not just asking about how a 340 cam goes in a 318.
If you want to know how all this effects engine performance, then I suggest you download Engine Analyzer from Performance Trends. From memory you can use it for 10 days before you need to register it. If you have a spare computer, put it on that and when the trial period ends, just re-format your hard drive, load up your Windows operating system (XP would be fastest) and reload Engine Analyzer.
Get some generic head flow numbers, a bunch of cam specs and spend a weekend playing with it.
You will learn more from that then a 1000 questions here.
