t56 2pc seal flywheel # ?
well, I went to the machine shop (really one I was told was good(sure
) any way I tried to tell the what I needed and the kid just looked confused. so I dummied it up for him and said I was just putting a older 2pc 350 in a 96 camaro lt1 with a 6-speed. holly cow I told him lt1 now he keeps looking for this setup but, does not listen when I tell him it does not need to say lt1.
I mean what the #^%^! well then I say to him can you drill the stock flywheel for the old bolt pattern. and I ask him if it will be too weak. he starts telling me it will be weaker (
I thought that hence the question. will it be too weak) I don't think I will ever go back there again I will just go to the machine shop I usually go to he may take a long time but, he really knows his stuff and I know he can find the flywheel part number

Visit www.centerforce.com and get the part #, it's so easy even I can find it, then check Summit, Jeg's and your local speed shop.

I guess I am slow, I don't see which one I need. the book he had showed what I thought might be the right one but I don't see it here. his book said something like (93-97 camaro w/6spd 2pc seal) he would not let me get a good look though.

go back to the machine shop. avoid the kid, and find the old guy that actually does the work.
every good machinest ive ever seen/heard of is atleast 35.... i think thats because it takes about 15 years to just get good.

I stopped by my normal machine shop and like I thought they did not want to do the whole bolt pattern thing. they said it "could" hold but, those cast flywheels have a habbit of blowing up when beat on too much. they went on further saying that for the money it is a real good Idea to just buy the steel one. you know the funny thing is they are a smaller shop and in a real small town but, he knew right away what I was asking and knew just how the clutch works. If I did not know any better I would have thought he just was looking at one before I came in. he is going to see if he can get me a better price than summit or jegs can.
