Thanks for looking and if anyone thinks i will have problems please let me know.

uhhh..... i hate to say this but you kinda got ripped off
if you look at the lobes on the cam they all have wear, and most roller cams dont have that much, but this one looks wore out

its kinda of a big cam for the street. what kinda heads are you using?

new lifters (summit usually uses good parts)- http://store.summitracing.com/partde...5&autoview=sku

personally i wouldnt,
cause you could get new for around same price
id also wait for a second opionion


what kinda heads are you going to use?
is this for racing or what?

if it isnt for racing, a hydraulic flat tappet cam is a WHOLE lot cheaper and it will last for ever if treated right

I disagree, you should follow through with the transaction. If you don't intend to pay you should have never bid. True it may be a little, or lot worn, but you got to see pics before you bid. So you had the chance to ask questions before as well.
Did you check his feedback? Does he have a bad history of selling stuff with inaccurate descriptions? All the things you should check before you bid. Don't bid if you don't intend to pay.
The seller is the one getting ripped here.

cam

If you won the sale you need to buy the item...

I am not sure exactly what your question is...Are you asking if the cam is ok to use??? or is it ok for "your" intended usage???? I have found that pictures always make any marks look 100 times worse then they really are. So you need to wait untill the cam shows up and you can see it in person and describe the condition to us...

That cam needs 10.0:1 or better static compression to work... It would not be a good choice for daily driver for the average person.

What is the intended usage for this engine????

you may or may not have to pay for it. If the item was presented in "good" or "perfect, like new!" condition, you should contest it if you feel its worn. Roller cams should not see much wear.

However, if the person said that its used, as is, you need to pay.

I`ve yanked stock roller cams out of GM engines that looked far worse than that and they still ran good and did there after, the cam looks to me like it has the normal scuff marks, and what was said about pictures is true, the shadow always makes it look worse.
