    I see they fit Saturn all the way back to 91.
    So Does that mean they are Saturn lifters that Cadillac uses?

    Re: 99 STS Project

    Something's funny - CompCams, in their 37mb online catalog, does not show any cams for any Northstar. Do they have a special catalog for Northstar ? - or is this NIB set of cams a regrind ?

    Re: 99 STS Project

    That's either a second jobber marketed regrind or a T-shirt, depending on which Comp Cams 99-999-3 will open - 5 hits. ???

    Members on the S10 forums claim that part number is for the 2.2L 4 cylinder.

    Re: 99 STS Project

    ...........a picture of the CompCams Northstar cams and the NIB CompCams box with ID.

    I can't find the darn things anywhere, and CompCams and Google can't seem to come up with any help, either.

    EDIT: Hah !! You already answered this over in the old "Northstar Cam Specs" thread. (We're back to last summer again................) Read the whole thread, troops - these cams are regrinds for something other than a PCM-controlled FWD Northstar daily driver VIN 9 or VIN Y pre-2000 engine.

    EDIT # 2: The CompCams P/N 99-999-3 is a generic "Engine parts" number - looks like all sorts of stock and special work falls into this particular number. Look at the .050" lift specs for those two cams and you'll see that they're a fairly mild "street" regrind. Running durations of 212* and 224* are common. The high torque/low rpm cams I use in my Olds 455 engines for boats come in at durations (at .050") of 204 and 214 - just about 10 degrees less than these Comp units. It would be interesting to compare the posted total lobe lifts with the OEM Northstar lifts.

    Re: 99 STS Project

    i did not reseal my case when i did my heads. i wanted to get in/get out quick. a major refresh of motor is nice but how long will you keep car? making it nice for the next owner is ok i suppose. i put new rings in my 66 mustang and did a valve job. sure was easy compared to the northstar.

    Re: 99 STS Project

    Nice work. Mint heads. Check and double check the valve stem seal installation.

    I'm gonna wait 'till someone asks "Hey, Joe - why did you pack the oil pump with vaseline ???"

    (Is that the original Gerotor pack ?? It looks brand new.)

    Re: 99 STS Project

    did you mill the heads? sure are clean. you would think the squish area is where the carbon might build up and cause knock. i cleaned my heads very well. whose to say what they look like now. 3yrs later. i helped dad rebuild a 68 327 from vette. had major crud on valve stems. i spent a long time cleaning valves/heads and took it down to machine shop and they said all valves were too worn. had to buy new ones. new valve guides too.

    Unless I miss my guess, those heads have been cleaned very well but not cut.
