    Some crazy lift what does the stock stall feel like with 4.56 gears.

    pretty damn good, instant torque kind of like a diesel, will lay rubber for 10ft or so(both tires very very sticky) It says its a lsr series cam which is supposed to be good for low end power???

    It looks like a cam that works for a stock stall but that lsa looks like it should be 114. I know the smaller the motor the bigger a cam of any given size acts bigger. If they reccomend it go for it, it might not want to idle low enough for a stock stall.

    Might work good for you. Going to need a good valve spring upgrade. It says 1300 - 6500 rpm range, but I'd still look for a small stall convertor !!!

    Cam looks good. I'd bump it up to a 113 LSA to make it a little smoother so it'll get along better with the stock converter.

    Also make sure you run a good double valve spring that's rated for a true .650 lift.

    I will be defiantly be running good springs, that much lift has me worried, the comp guy says nothing to worry about. Will going to a custom grind at 113 really make a difference? I know stock is a 114 lsa .190/.190 .47 lift or something. What kind of power do you think it will make???

    With a big truck on 33" tires, I wouldn't really be worried about what kind of power it'll make on the dyno

    Do a 113 + 4 (advance) and it'll make plenty of power everywhere and be perfectly driveable.

    Doesn't a custom grind cost like double?? I am interested in more low and mid torque over horse power anyway. I want something that sounds mean as hell, but still very drivable(cold weather in canadian winters).
    just curious, like 40hp and 40 torque would make me happy at say 2500-5000.
    What do you think, am I crazy??

    Is this the right direction

    Ok so I wanna get the cams over with asap, and I really was leaning towards comp cams buttt...
    What size should I get, or any other brands that make a good cam that isnt crazy pricey?

    Both of you need to start your own threads to get your specifics answered and to not hijack the op's thread.
