I am looking at a cam from a local seller on craigslist and he told me it wasen't a custom grind. He says he has a Comp cams 240/242 581/581 113lsa

Is that a real cam that can be bought without being custom ground?

 

ground

 

might be an old one. id ask for the number that is on the end of the cam. i dont really trust anyone on craigslist.

 

^^^^why is that???

 

liars...

 

exactly why im being cautious. Every car on craigslist has under 10,000 miles on a rebuilt engine LOL!!!!!!

 

I might be drunk but that looks like low lift for such high duration

*ignore me if I'm just an idiot at the moment*

 

That's what i was thinking...

 

there are allot of scammers on there. you have to make sure you look the merchandise over really well.

 

.581 with a 1.7 ratio and a .615 with a 1.8 ratio. its not far fetched, it was probubly designed for the higher ration rocker.

 

Either that or it is in fact a lower lift , high duration cam. If it is for real, it would be a lot easier on your valve springs, and still make pretty decent power from the duration vs the high lift.

I am suspicious though, especially after you mentioned craigs list, and the fact he said its off the shelf, or at least not custom.
