Well I am going to replace my lifters and cant decide what ones to use. Comp Cams Rhoads Lunati? I have attached a link to a summit page to my narrowed down choices. What ones would you guys use? http://www.summitracing.com/search/...Quantity/Sold-as-a-set-of-16/?keyword=lifters
If you are replacing the cam also, then maybe you can get a package deal with a cam kit? It might make your decision easier. Just a thought...
I am going to be replacing my intake and valve covers so I thought I might as well do the job while im in there. Not to mention they are old.
i was told but dont have any proof that all the aftermarket hydrolic flat tappet lifters for older motors like ours are made at the same factory. so if that is true then all those lifters should be the same. now as to why are you changing them. the lifters and cam wear into each other. you risk flatening a lobe on your cam by changing the lifters. also the head of the lifter has a tendacy to mushroom out and make it difficult to pull out of the block. unless you have a ticking lifter then there is not any reason to change the lifters.
the best thing to replace that wears on a motor is the timeing chain. that has nothing to do with changing the valve cover gaskets and intake. if you looking for something to do while your doing that job, its a good time to put roller rockers on.
I do hear a ticking noise sometimes. I was wondering where this ticking is coming from. It usually goes away with a oil change though.
Just buy the summit generic racing lifters. They are made by Crane Cams anyhow so your getting a good product with a low price. http://www.summitracing.com/parts/SUM-HT817/ part number SUM-HT817
When I had to change some hydraulic lifters in my Grabber I just used the stock ones from Merles automotive. About $3 each. They ran up over 7000rpm with no problems.
So even if I used some break in solution I still run the risk of damaging my cam with new lifters? I was under the impression you just treated it as if you installed a new cam. Idling the car at 2200 rpms for 20 minutes and so forth.
Not sure if you need to do anything. I changed mine out at the race track. I changed out 2 of them. Then just ran some more runs down the track. I didn't do any break in at all. But then I never slept at a Holiday Inn Express either.
you can get away installing new lifters on old cam , but are taking a risk new cam old lifters. unless one has collapsed i wouldnt change em. the timing chain is a very good idea, use a double roller , factory chains depending on year were retarded... use plenty of cam lube on bottom of lifters if you decide to go ahead with lifter swap . hope all works out for you.
You can "SOMETIMES" get away with installing new lifters on an old cam but it is always risky. You are better off in the long run to change the cam and lifters as a set. Cam lobes are ground with a taper to them and lifters are ground with a dome on the wear surface. The two surfaces wear together in the initial break-in and replacing either component can be disastrous. Some people are lucky and get away with it some of the time. Some get away with it initially but have failures later. Some only get three days before it all goes to... How lucky do you feel today?
