    ........... but 1993 (the early, early Northstar years) is a LOT different from 2000 and later, mechanically ............... Blanket statements about these engines can always come back to haunt you ........

    Re: Do not stud a Northstar

    I have always replaced the bolts. I have never reused them. That is not my point. The bolts are not torque to yeild

    This is a few pictures of the type of work I do

    Re: Do not stud a Northstar

    I have news on this. I tore my cammed Eldorado down for R&D at 18,600 miles since the build. I beat the living hell out of that car, at speeds that nobody needs to know about. The engine is still in excellentcondition.

    I know where the weak points are. I am a step ahead.

    AJ is on to something, to an extent. But to throw studs out of the equasion is simply ignorance. I am open minded.

    When I say I am a step ahead, I mean just that. Take my word for it. Because of other individuals frequently on this forum, there are things I simply won't say until the time is right. Anyone interested can like and follow the Northstar Performance facebook page. This is where updates on the teardown will be.

    What year manual states to replace them?
    Every year I just looked up states to reuse them.

    Does this information apply to a 94?

    Re: Do not stud a Northstar

    How about the reuseability of gaskets listed, and does that information apply to the 94 N*?
