    i have a 350 roller motor from a 98 vortec truck....i'm converting it to run without a computer, and i'm using just a performer intake for the vortec heads to use a quadrajet....

    anyways, the cam in the motor now, dont have a mechanical fuel pump lobe, so i'm gonna have to buy an aftermarket cam....

    i want bottom end obviously, .....anyone have any numbers or recommmendations????

    my trucks an 85 bytheway:rolleyes:

    get a copy of desk top dyno and see which cam makes the best power for what you are doing with it. you can also call places like Bullet Cams and tell them what you do with the motor and they will grind you a custom cam for around 240.00. Comp cams did mine, 785 lift @320 duration on 114 lobe center.

    MMMMM, maybe my crane hydraulic roller is a little too aggressive then? I mean, .700" lift seems like it may be a little too much for a truck motor, but mine seems to do ok. Seriously though, I have a Crane hydraulic roller that is .488/.509. Either you or the person you talked with at crane is confused. Jegs/summit have listings of most of the cams that crane makes.

    Don't get a cam because of price. The cam is one of the best place to pick up power and getting a cam that matches your motor perfect is well worth the extra $100. My cam is 276/284 adv. duration, 214/222 @ .050" .488"/.509" lift, Desktop Dyno rates it at 434 hp @ 5500 RPM and 470 ft.lbs. @ 4000 (440 + ft.lbs. @ 2000). Using desktop dyno it is just about the best match I could get without a custom grind. Mine has the same vortec heads, but its a 383. Your 350 will want a little less cam. Should give you some idea of the power you can make.
