    I have contacted comp cams and crane cam for cam recomendations. My set up will be:

    Engine information:
    Make: Ford
    Year: 1985
    Cu inch: 302 V8
    Compression ratio: 9.0-1
    Cylinder heads: ProComp ported, intake 210/exhaust 70/ combustion chamber 60cc Valve size: int. 2.02, exhaust 1.60
    Rocker Arm: roller Rocker ratio: not defined yet.
    Intake: carbureted, Holley cfm750, blower Weiand 174
    Trans: automatic
    3500 stall converter
    Rear gear ratio: 4.11

    And compcams recomended:
    duration @ .050 of 230 236 and valve lift of .544 .555 on a 114 LSA. This cam will make strong power with your supercharger and pull hard throughout the entire power range. It will work well with your stall and make power to about 7000 rpm.

    What do you think?

    If this is a mostly street driven vehicle I'd use the Comp, that Crane isn't going to be very friendly & at almost .600 lift likely would be hard on valve train components......

    You're going to need a better block than a weak, light weight 85 block.....................KABOOM!!!!!! It'll have problems with the head gaskets sealing before it 'splodes too. Drop the supercharger and it might live awhile. Or find a 68-79 block to use as a foundation. These blocks have 16 pounds more iron in them than that 85 block.

    Yeah,I agree w/ the other guys,better blk,and the comp cam.However,that cam will have more of a tendency to make power in the upper RPM range because of the wide LSA,108 will rev up quicker and would make a little more torque in the midrange.
