Hello all, need some good suggestions from the cam experts please. Am getting ready to finish my car. Want to install the right hydralic cam. What i have is a 66 396 rebuilt with 30 over stock pistons they do have domes the cast number on the block is 3855961 The heads are 3872702 mortec says 98cc. I need to know if you have any idea as to the compression ratio? This is going in my 68, turbo 400 trans, 2000 stall converter, 3:31 gears, 28 inch tires. This is just a weekend cruiser no drag strip would like a little ruppity rupp and low end tourq. This is what i have for now money is tight so i can't change pistons or heads at this time to lower the compression which i'm guessing is going to be high. Thanks for all your help and suggestions.
