TPI/LT1 cam?
TPI/LT1 cam? I have a TPI cam that I bought from comp cams but now my 70 with TPI is going to get an LS1/T56. So I have a brand new cam that I want to put into my 73 C 10 that has an LT1/4L60E setup. From what I have read I have to change the dowel pin in the cam. So my question is can this cam go into an LT1 or I am just hoping for something that can't work?
He is wrong. The dowel length is different but a dowel is needed. He has never seen the inside of an engine and his facts come straight from his ***.

Scotty, what I told you is from experience. Dont listen to the other person in here. He is jealous, has a vendetta against me, and refuses to let his swollen ego subside so some actual technical content can be discussed.
What I told you is correct. If you have a 92-94 yr opti with spline drive, you do not need the dowel pin. You can grind / cut it off even with the cam gear and you wont hurt a thing.
On 95-97 models you need the dowel pin to be the correct length because it drives the opti. Too long and it can damage the opti.
.620 is the length to shoot for. It can go as long as .685 before it starts to bottom out in the opti and could cause damage. So .620-.650 is safe.
If your dowel pin is too long, you can cut it down to the correct length. If it is too short, you can sometimes pull them out, or have a new dowel pressed in by any competent machine shop.
If you decide to use the cam, it will work, I have posted the steps you need to take based on actual experience with both kinds of optis, several cam swaps and engine builds, and multiple different dowel lengths on the cam.
FWIW
The cam sprocket bolts to the cam using the three cam bolts. Therefore, as long as the cam sprocket is lined up with where the dowel goes, it's fine. The dowel does nothing, drives nothing, and is really only there for reference.
I'll admit that most people just leave the pin at the recommended .300" and don't cut them off entirely though.

Extra parts GM installs a dowel pin in 100% of their engines.
All reputable engine builders install the dowel pin on the cam. Would you take your motor to someone who told you what you heard here?
Some will say it isn't needed. OK so do you need to put all 5 lugs on a car? Do you need to torque every bolt?
I have seen a SBC water pumps not leak with half the bolts left off! Just because you can does NOT mean you should!
There is a right way and the half assed way. You can choose to do it either way, personally I do it right. This is a perfect reason why other sections on this site call this section the idiot pool--because soo much bad advice is given daily here.

Pin has no ballance effect on the cam what so ever so if you don't need it don't use it. GM also installs Bolt holes all through out thier cars and engines that are not used as well.
