a friend of mine just gave me a cam that he used last year, it is a comp. cams 480 lift thats all he told me.... (he stepped up to a 510 isky),.. this is going in a bone stock 350 with 882 heads stock alum. quad. intake, he also gave me some cam lube, should i put new springs and lifters in along with the new cam? im going to put a new chain on it but was just wondering about the lifters and springs...

Yep!I would.I would go with springs from Midwest Motorsports.The "z28"springs.If it were me. just my two cents.

Bryan, I personally would buy a cam package from a dealer.......with the cost of new springs and lifters.......if you bought a COMPLETE CAM PACKAGE the cam it's self would only cost you $20-$40 dollars.......

Then you get the correct springs for the cam with the information for the correct installed spring height, and seat pressure.

Plus you get a cam card, that will tell you where to degree the cam in at.....

I just feel for a few dollars more you could have a new cam, with the information from the manufacturer to install it properly.

If you still decide to use the cam your friend gave you......yes, put in new lifters and springs........I used to only run a Z-28 spring 10 nights then replace then.....You will find broken dampers if you go 12 nights. You may want to look into a little more expensive spring......I forget what we used to run now.......but it's life span was twice as long and only 30% more money.....

I'm sure someone here can tell you more about a better srping for the money than a Z-28 spring....

The package deal will be cheaper in the long run.....more up-front cost though.

There are better springs than the z28 springs.Thats a given but if you are using hand me downs then sounds like your on the same budjet as me.lol I pesonally would not spend the money for better springs.Cause if you dont like that cam.You have just lost money.More expense means more lost funds.But if you plan on just running that cam for a while then buy better springs.

its always good to have your cam match the rest of your motor, it might have worked ok in your friends motor but might not in yours unless you have the same heads, intake ect. You would be better of buying a package deal suited for your particular aplication, you'll be money ahead that way

Bryan, that's why I tried to give you as much information that I could so you could make a informed decision on what is RIGHT for you.........If you planned to try this cam, the Z-28 springs would be fine.

If you planned to run this cam all year, the cheapest way is good springs.....in the LONG run it's cheaper.

Cheaper is only good if you stick to the plan.....if you plan on changing springs after 10 nights the z-28 are cheaper. but if you run them 15 nights and drop a valve from a broken spring NOW what is cheaper??

Only you know the right answer for your budget and racing program. All any of us can do is give information.

good luck, Jeff
