    I believe it was a 114 or a 112, but I'm sure it's a 114

    So going with the MTI Stealth cam would give a smoother idle due to the higher LSA.....correct?

    Do i just need to install new springs, retianers and locks for the new cam, if i keep the stock rockers do i need new pushrods?

    Well i got a new cam for my Silverado today, is similair to a stock LS6 cam, but with more dur@.050

    Specs are

    .550/.550 218/218 on a 117 LSA. Im gonna get some 918 springs, and a tune along with the LT's and ORY and a Volant CAI and the truck should make real close to the same power numbers as the onin the first post here.

    I believe the truck ran a 13.6 with no converter and 3.23 gears (yuck!), since there, he's installed a 3000yank we had here and 4.10's. I'm sure it's easily in the 12's by now. I haven't spoken with the customer since the stall and gears.

    As soon as I do, I'll post up.

    later,
    allen

    oh no, it ran that after the mods, 13.6 was with the mods above, now i'm sure it's faster with gears and converter.

    yeah that was how i took it! 13.6 isnt that bad! at all really. thats w/o a some kind of rear end and a good set of tires correct? i mean a cam and a few small mods is really just scratching the surface

    That's correct, no posi, stall, tires.

    This was a decent sized cam, so, it really brought the power band up. This requires a converter and gears.
    So, 13.6 is really good, it only shows how slow it took off the line, the mph was good though, indicating HP is strong.
