Cam / Compression Ratio

Every engine I built for my car I planned thoroughly with the end result as my guide....for example, my current engine I wanted to be able to run at least 10.4 in the 1/4 mile in the heat of summer so I could comfortably run a 10.5 index class at the local track. This goal dictated what parts I needed to achieve the goal. I also wanted to be able to keep my car street legal so I could drive around town....this made a rather narrow path for me to walk with the build, but it gave me direction. I also over shot by just a little on the power, but hey, I'm not complaining, lol.

Like Rat Bastid said, if running pump gas is important to you, then make that a must in your build check list and plan around it. Most things you can make work....unless you have some crazy unrealistic goal like running 7's in the 1/4 whilst getting 30 MPG with the air-conditioner running.....now that I say that, I'm sure someone out there will be like "Challenge ACCEPTED!!" :lol:

Long story longer, start with a goal in mind, then build engine to fit.
