8ba camshaft I.D.

[swanwaco32]

I have a never been run camshaft with the markings stamped on the end C8RT? It appears to be a regrind. Need help identifying it. Thanks John

I suspect it's a Canadian 49-51 Mercury (Ford) truck camshaft. 8RT is a truck marking.

I concur. And, IF it's a re-grind as you suspect. the only way to determine what it actually is is to degree it.

 

[19Fordy]

Yes, it would be interesting to know what the new "grind" is all about.
Can you check it out? Is there an easy way to check it (on the workbench)
with a dial indicator or micrometer? I would like to check one out also.

All you can do on a bench is measure the lobe life with calipers or a micrometer. To check duration and open/close events you would have to do it in the block and use a degree wheel.

That's right. I have a block set a side specifically for that purpose.

 

[swanwaco32]

I will check the lift and let you know. Thanks

Just check base circle diameter, that will be a good indication if it has been reground

 

[swanwaco32]

I checked the lift and it is .397

 

[flatjack9]

Definetely reground.
