I purchased a cam along with a cracked block at a swap. The cam was in an LS2 mallett corvette. I am building a 6.0L iron block that is bored .30 over and debating on using this cam.


The cam reads crower I think on it. The engraving is light
Also:E60776
251896


I just want to figure out if this cam would be good for my setup. LS3 heads and intake. I am worried about PTV clearances.


Can anyone spec this cam out with those numbers?


Thanks!
