Disadvantages of a reground cam: When compared to a newly manufactured
1) Worn bearing surfaces creating a loose fit between the block
2) Worn distributor drive gear teeth causing sloppy distributor timing
3)
More duration when ground to restore lift (changed ...thanks Marco!)
Advantages of a reground cam: When compared to a newly manufactured
1) Less cost
Disadvantages of a reground cam: When compared to an unrestored original
1) You really need to measure the overall lift of the original cam and compare it to the specs of a reground. A really good original could be as good as a reground cam if the lift is very close because the duration will be better.
Advantages of a reground cam: When compared to an unrestored original
1) The lift will be back to spec but again, you need to measure all aspects of one cam to the other.
If you have more than .004" clearance between the block and the cam journals, you could notice a nock.
