What is the size of the stock camshaft dowel pin? Mine sheered off and I need to press in a new one. engine is stock 2.8 in a 1987 fiero gt

No one has a camshaft laying around that they can check or a camshaft sprocket?

Hope you get some help. All I have been able to come up with is that it is metric, and smaller than 1/4". Can you remove the part that remains in the camshaft and measure that?

I have been trying to take out of sheared dowel pin, I figured it would be way easier to just drill the size of the dowel pin in there. Its like inset in the cam, not flush.

I am considering just omitting the dowel and just using the holes to line it up. Is this a bad idea?

I have a 2.8 on a cradle with the timing cover removed. Next trip to the garage 13 miles away, I can measure it. Could be tomorrow or the day after for sure.

That is a bad idea. The pin is there to maintain cam timing. The pin is probably hardened, and is going to suck to remove. YOu could over drill to the small block chevy size, but getting the hole centered well and drilled accurately with the old pin in there will be difficult as well. You might just want to replace the cam at this point!

I have my a 3.4 pushrod cam, I believe its the same dowel.

It measures .236" diameter or 6.0 mm
