OK.. I am confused about this....adding an LT1 cam thing.
I just spoke with a teacher of the automotive department at a local college. I told him that I am getting a cam for my engine. He said I need the origional lifters that were used with the cam, and I need to match them with the corresponding lobe that the particular lifter went with. Is this true? If so, and I was not sent the lifters with the cam, what would I do? He said I could just get all new lifters for it, but it wont be the same as the origional lifters. He said something like they will wear faster if not used with the regular lifters. I don't know though. If someone could fill me in on the specifics with a cam install, I would appriciate it.

Thanks

 

That is true if you are using a used solid lifter cam We have roller cams that do not "wear" to the cam. They also require no break-in period. It is a good Idea however to keep the lifters you take out of your engine in the same lifter bore. The lifter will make itself "known " to the bore and It should be replaced properly in its original bore.

BTW, I am in the process of writing a teck article outlining the cam swap process. If you are not doing the swap really soon you can use the article to help you.

when are you going to be done with it, i plan on doing the swap starting sunday or thereabouts

 

Ok...So you mean that I do not need the same lifters that origionally came with the LT1 cam? I thought not using the same lifters will make it wear faster or something like that... but I am going to go with you guys on this one. What is the lifter boar anyway? is that some place in the block where the lifter sits? Swaping in the cam will be the first time I have been inside the engine. The most I have done up to this point is headers. So forgive me if I ask a lot of questions. The second thing I am confused about is the cam pin...what is going on with that? Some say to cut it off, and other say to only cut a little bit off. Maybe everything will be explained in your tech article.

 

Roller cams dont really wear down. A roller cam with 60,000 miles will look nearly identical to one with zero miles except there wil lbe a slight mark where the lifter hits the cam all around the lobe.

Other than that the L03 has hydrolic roller lifters and the LT1 has hydrolic roller lifters.

 

Your current engine is equipped with hydraulic roller lifters so you can reuse them. I would reinstall them to their respective bores. The LT1 cam has a dowel pin that is .600 long, Cut it off to the lenth of your oringinal cam (.300)
