Ebay 458DA pulley, is this repop?

Please help educate the masses.......

When these 458 pulleys are installed on the pump, in the car, they are quite difficult to tell Original GM from repop.....

Given the asking/selling prices ($400-$500) for "real" 458's isnt the money better spent elsewhere.........like on "real" cam lifters, "real" valve springs.

I'm for OEM original parts almost as much as anybody, but some repops are so close, especially in the installed position

Go ahead, flame suit on !!!!!!!!

That would be fine as long as the repops didn't wobble, break at higher rpm's, etc

Someone finally PM'd me with the exact reasons the pulley I pictured is a repop.
Now I won't be guessing about that anymore.

If the person that PM'd me is willing to share the info, I'll let them help, as it's not really my info to share.

It appears that the pulley in question does not have the Oval shaped outline around the P/N and the rear has "lines" instead of "knurls" as per the original. These lines usually indicat a pulley that has been spun formed instead of stamped. The knurled marks may have been caused by a holding fixture while a particular operation was done, such as the V groove forming. I had a pulley that was identical and determined it was a repo although very nice quality. I have a problem when sellers try and pass these off as originals and someone pays $600 for a $100 pulley, thinking they purchased an original.

As Paul stated, originals have an oval outline around the stampings. Here is a photo of an original.
