    cam comming in

    ok so here are the specs on my cam(itll be installed straight up). i took a look at the cam bearings and they look great no bad marks at all. would anyone recommend changing the thrust plate though, mine had like one mark on it in one spot. anyway here are the specs on my regrind for my 02 gagt...
    206/208 dur .495/.495 lift, 113 LSA

    what do yall think? im getting it stabbed in whenever it gets in, i have the engine pulled and the front cover off waiting for it. i also need to get a new timing set due to the stock one i had looked like crap and flopped around when i took the front cover off

    similar to a stage 1 from milzy, just a little less duration, and more lift. and a 113 lsa vs 110...

    I'll be curious to hear how it runs. I wonder if you'll have yours in before I get my motor in.

    My stage 1 is

    .305/.308 lobe lift (.488/.493 valvelift),
    209.4/213.1 duration,
    110 LSA, 108 IC

    Got Lope?

      idk where he gets his ideas from, but i will like this one im very sure. i wanted the higher LSA incase i run nitrous...but i like the wide LSA and low dur for a smooth idle. i like the higher lift to help out the entire band...this is a mild cam though, and that is what i want

        I run nitrous on a stock cam now so I'm not so worried about the LSA, I don't seem to have any issues. And I love a lopey idle

            I'm interested in hearing how that'll work out, as that'll be fairly close to the grind I'm planning on going with, although I think mine will be a bit more tame than yours.

            Anyhow, the thrust plate sounds like it'd be fine, as long as it's not really torn up. Do you know if there's a thickness spec on it, though?

            Honestly, I'd still rec replacing the cam bearings, along with lifters, especially if they'll OE . . . but that's just me, I'd rather be safe than sorry, especially with a DD.

            Question, are you running a stock PCM, a custom tune, or some other setup? My last concern over mine was if it'd run decent with a DHP PCM, curious how yours will turn out?

            Correct me if I'm wrong, but did you pull your motor completely out for the swap, or did you manage it still in the car?

              you can do it in the car but its a pain, i took it out while i had everything else off of it. and i have the PT from DHP. idk how it would run with a computer and nothing to tune, more like crap, and mine is tame, very tame. im changing out the lifters with brand new ones, but im keeping the bearings because they look great. idk about the thrust plate either. thats about it.

                  Are you going to get custom pushrods?

                    and this is my only reservation with ordering up a cam, as I don't have the PT yet, only a DHP PCM. And with the possibility of me changing up to a different shop in the near future, I've been wanting to just go ahead and get the whole upper end done while I still have easy access to the shop equipment and the lift time needed; I don't know how picky other shops would be over personal work, and even fewer have the engine building equipment we have . . . I guess I could just take that risk and see how it would run, though; keep my fingers crossed that it would run decent enough until I can grab a PT

                    Anyways, defi keep us posted, man! Lookin forward to some numbers!

                      ok so an update. i found something interesting when i got the cam in. i measure it and they used the wrong RR for my valve lift. they used 1.5 instead of my stock 1.6. so anyone wanna guess what my new lift is, ill tell u the old lift they calculated was right at .454....

                      also i put the cam in and with the stock pushrods and rotated the engine and the LS6 springs work great. there is plenty of room with the springs.

                        How much preload do you have with stock pushrods?
