    Cam Selection, have specs.

     



    Well, as much as I hate to do it, I need some Cam help.
    This cam is for my 350 that I am dropping into my '70 Nova pretty soon here. Already have the longblock, heads, and other parts, down to Cam/lifter/pushrod selection. I know you guys want to see specs before pointing a cam out, so here are the parts it's going to be working with:

    Car:
    70 Nova
    Kitted TH350
    Small (stock?) converter
    2.73 gears (for at least another month)

    Other Valvetrain:
    Dart Iron Eagles
    2.02 / 1.60 Valves
    72cc Chambers
    185cc Intake ports
    Comp Cams 995 double springs (1.700" installed height, 1.050 bind height, Max lift ~.600", 441 Spring rate, with dampening)
    Comp Cams 4808 Guideplates
    Summit 1.5:1 roller-tip rockers (non self aligning)

    Other motor:
    350 Ci Block, 23* valve relief pistons, standard ~.035" deck height
    RPM Air Gap intake
    Edelbrock 700CFM carb
    Accel Blueprint distributor
    1 5/8" Primary long-tube headers.

    Any idea for a cam to run in this? I want a halfway decent idle, certainly don't mind a bit of chop though. Mostly for street use, especially until I get a 3.43 rear end, and a stall, at which point I may recam this motor. So, pretty much, what will give me the best street performance? Looking at a quench figure of about .075" (yuck), so keep that in mind.

    Also, should I use the stock 7.800" Pushrods with this motor? Thanks alot.
    I appreciate the help, getting this whole valvetrain thing down one piece at a time.
