Today I'm putting the engine back together. One of the things I wanted to add was the above mentioned fuel pump rod. This has a "bolt" which goes thru the threaded hole in the front of the block to keep the rod from rotating.
Simple right?
But.. the damn hole is blind, did Chevy change that sometime?
When?
Is there a fix i can do?

we used them on high pressure,high volume alky fuel pumps to prevent the cam fuel pump eccentric wear. electric pumps solve this problem but some places you are not allowed a electric fuel pump.

I am running an erson roller cam.
I read some where the roller tip pushrod was a good thing so you dont wear of the eccentric on the cam,( a friend has developed this problem).
So I thought I'd avoid the cam wear with the pushrod. But as i said the hole thru the block is blind. Next time the motor is out, I'll drill and tap it. If I can avoid electric pump i will,don't care for the added noise. It is after all a street car and i like to travel long distances with it.
Thanks for all the input.
