    464, stage 2 SE aluminum heads.
    10.91 compression on this next build.
    Looking to run pump gas.
    Looking at the TA-510 cam or open to Some suggestions.
    I have a spx intake & 1050 dominator.
    Motor will be going back in the S10 pickup.
    Truck in full trim weights 2945lbs.
    Turbo 400, fti 4000 stall & 430 gear.
    If anyone has a good cam up for grabs, let me know.
    Thanks

    You can run pump gas with that compression,and especially with those aluminum heads.

    Shouldn't be a problem with a healthy cam 304 or 308 s ...or even a big hydraulic ..should make good power ...my engine is 11.2 on pump...the 510 cam should be fine as well

    With 10.9:1 static compression, and the TA-510 cam on a 106* ICL, the Dynamic Compression Ratio will be 7.65. Between that and the aluminum heads, pump gas should be no problem at all.

    Yes,
    And be a lot easier on the bottom end assembly.
    Will be using stock rods with ARP rod bolts this time.
    Turning it 6500 max, shifting @ 6000.

    Briz,
    What solid roller do you have? I prefer to run those.
