    Default SBC Cam ?

    Working on building a SBC 383 stroker for my truck and im getting confused when it comes to picking the right cam. this will be my DD and im not to worried about gas mileage.

    So far i have the non roller shortblock and a new set of Vortec heads ready to bolt on. im going with a Edelbrock airgap intake, Holley 650cfm carb, HEI ignition.

    Now the truck is a 90 1/2 ton with stock TQ for now, i will change it out later when i beef up the trans and rear end.

    so ive been looking at these cams , but dont really know. Not sure need some input.

    Does it still have the tbi or is it carb'd ?

    Edit in: Okay, I think I can read...LOL....Carb it is.

    For a truck I'd go simple. If it's 4wd I'd stay with the good old standard Comp 268 High Energy. 218, 218 and 110 LSA. Should pull real well and give you good power to maybe 5000rpm or so. Peak HP should be close to 4500rpm. Shift low-mid 5k rpms.

    If your worried about more power past peak hp rpm and don't mind giving up some bottom end, then you can go with a split pattern on a 112 around the same intake duration at .050.

    BTW, remember, if you have stock Vortec heads they are lift limited because of spring/retainer/to guide clearance. Some say less than .480" and some say less than .460" . Most are fine close to .480", but if you are going to use more than .460" you should have them quickly checked to make sure you are okay.

    I believe the 268H has .454" lift. Extra bonus.

    Thanks , this is a 2wd street truck. been a project for the last 6 months and want to keep it very streetable

    not really looking for low end torque, more of a performance build.

    it wont be pulling anything and will most likely end up as a weekend toy when finished

    My Vortecs have been machined for the bigger springs/lift, threaded studs and guide plates already

    There good to a 550 lift

    Ahhh, okay.

    224,224 or 224,228/230 on a 108LSA and 2500 converter and 4:10 gears.
    Have fun ! For these specs I'd check ISKY. Tehy have a lot of cams on the shelf with 108LSA.

    I assume since you mentioned the Thumper Cams above that a 'semi-tough' idle is what your are looking for also ? If not, don't go by last suggestions.

    Some kind of Chinese air cooled piston? or maybe a rod journal cooler?
