One of my customers mailed me their camshaft thrust plate so I could countersink the bolt holes. He will be running a comp cams timing set that uses a torrington bearing.

The problem I have is that he sent me some cheap garbage philips head bolts... this simply will not do! I need to know what the thread size, pitch and length is of the stock camshaft thrust plate bolts.


Lets see who gets this one!

I thought thet were 5/16.... I'm using that timing chain and my bolts have a allen head insert

Assuming you're talking about a 5.0 HO block. I wish I had a micrometer here at the house, I have about 3 at the shop. I pulled one of the thrust plate bolts out of my 351w, should be the same. Measuring from the bottom of the head to the bottom of the thread is .70 inches, 1/4" thread. This is using a machinist's ruler.

Don't quote me on the thread number. Like I said, I'm using a machinists ruler and my eyes lol.

Nice quote adder lol.

I think they are 1/4 inch. I have to find some for mine when i get home. I had one break on me when the motor was in the 83.
