    What size engine? What gears? What transmission? What is your cruise RPM on the highway? What kind/size carb? What've you got for exhaust? Give everyone as much info as possible.

    268 is far too big for a fairly stock 305 or 350. It'd probably work fine in a 400 SBC in a truck with fairly low gears but it's definitely not going to work in an overdriven rig with 3.08s and a stock single exhaust cast iron intake 350.

    This past winter I built a 454 for my 71 Chevelle. I asked evryone around about cams. The best advice that I got was to call several cam companies and tell them what you are building, what your intendeed use will be. You will also need to know some basic info about the vehicle. Tires, gears, heads, intake, carb, exhaust, etc.

    Then once I had several part #'s.........................(This is the part where I get cheap) I shopped around until I found the right price. /forums/images/graemlins/thumb.gif

    Definitely call cam manufacturers. Don't waste your time calling Crane in the morning though, their guy is a total prick.

    Now just go to www.compcams.com and find their tech line phone number. Call them, give them that info (plus tire height) and let them know what kind of driving you do and they'll recommend the right grind for your application. /forums/images/graemlins/thumb.gif
