    I need to order a cam for my full race 73 Nova, but I know nothing about them except how they install and work. Can anyone recommend a good cam grind for a

    I perfer Crane cams. But I agree call the Tech Line. I worked with one of the techs there to pick out a cam for the performance I wanted

    Wow nice!!
    You need some more specs before you can make a cam selection, and even the tech guys will be guessing a little if you don't give them more info such as vehicle weight, stall speed, gearing......
    I assume with that setup you'll go ahead and pony up for a roller cam. Hydraulic roller lifters don't handle high rpm very well, so go solid. Tell the tech guy your car is FULL race and driveability isn't a concern.
    I'm a Comp fan, but I've had a Crane and it was fine. Lunati makes a nice cam too, and there are several smaller companies that put out nice stuff too.


    I'm just guessing here, but with a 10.5:1 compression ratio, I'm betting you could make more power in a more useable range with a properly prepped and matched single plane intake and single four barrel carb.

    Agreed. You've kinda built a motor that defeats itself. A tunnel ram isn't worth much before 4000 rpm and a low compression motor (compared to a track only) makes most of its torque in the low rpm band. You can't have it both ways. You need to decide where you anticipate getting the most use out of it and then make a cam selection. Rule of thumb is: Street-.525 lift, 280 duration, Track-Big lift .600 or more 300+ duration.
    I ran a B/Gas '69 RoadRunner for a long time.
