Anyone got anything....i know someone has to have atleast a little feedback

 

be careful someone doesn't sell you OEM, I've heard of that occurring..

 

Well, positive feedback and he has the parts listed as his old setup. Is there anyway of telling the OEM from say HKS or GSC? Anyway to tell what the duration is by looking at the cam?

 

I personally would never buy used internals. Id rather pay the extra hundred bucks and get new. That way there are no questions.

 

Yeah, thats exactly what im trying to figure out, wether it is worth it or not, just trying to figure out if you could really screw up cams that bad by running them. Trying to exhuast all opinions with all my questions answered and come to the RIGHT decision for something as serious as internals.

Same here.. It just sucks that I'm probably going to swap my hks 264's out with some revolvers and probably won't be able to sell the hks set :P

 

BIG +1 on this....used internals are probably not something I'd sink my money into. Unless it was a well known friend, but that would be a light maybe.

I'm looking at a used set of HKS 264/272 cams with 5k miles on them. The seller is reputable and sent me high resolution pics. What should I be looking for and what concerns should I have?

 

I bought used GSC 272s from a local guy. The cams looked to be in good condition when I got them and I sent them to my engine builder who inspected them and told me they were "good to go".

I now have a slightly lumpy idle and good topend

 

buying used roller cams in decent shape is fine, normal wear marks-lines, but no grooves. Cams having grooves, dents or dings from being dropped are not ok!

Roller cams are different from the horror stories that are associated with solid/hydraulic direct following lifters. The insides of the rollers that takes the wear.

The non roller lifter generates a wear pattern circle on the contact face of the lifter from the cam lobe, leaving a wear mark. When those components are swapped between engines, the center point of wear on the lifter relative to the cam lobe placement is shifted, thus you have an edge wearing on the cam & lifter creating a vanishing cam lobe, only to find itself in little bits within your oil filter.

If the cams came out of a running car with no problems, i would feel very comfortable in buying them.

You have to ask yourself if by saving that extra money is worth your piece of mind!

good luck

 

I agree with the above post. I've seen some incredibly strong Evos on the dyno running used HKS 272s. As long as there was no damage from dropping or physically mishandling the cam, everything should be ok.

 

I've had used 264's in my car and now running used 272's in my car without any problems.

 

I've got used 280s, they seem fine and I don't think there are anything wrong with them.

 

I would buy used cams....you ever heard of a cam shaft failing? I never have...
