Arrow How hard is it to change the cam dowel pin?

If it can be done without having to take it to a machine shop that is...

I'm installing a comp cam in my '94 engine and I will have to either cut or replace the pin on it to make it work with the 94 timing setup. I might convert to a 95 opti/timing cover and double roller later on, so I'd like to know if I can change it fairly easy or should I wait until I have all parts for the opti conversion?

I took mine to a machine shop and he had to attach a slide ram puller and it looked hard to get out.

Well, it's not grinding/cutting that I'm worried about. It's if I will be able to convert to a vented opti afterwards. Guess not. Oh well, the new stock timing chain/sprockets will have to do I guess.

The guy took it out of my cam and put it on a lathe the size of a honda and gradually took it down to the exact correct size. Best part was he only charged me $10.

I just measured it and cut it with a dremel and cutoff wheel. Being how it goes into the cam gear the length is not super critical. The correct length has the pin protruding about 1/16" on the cam gear. Thier is still enough material there to later have the pin pulled and replaced if you later deciede to convert to a vented setup.
