I bought a rebuilt 292 with about a thousand miles or less on the rebuild. The cam in the engine is a little too much cam to keep it a driveable street motor and I plan to change it. When I do, would there be enough of a wear pattern on the lifters to require changing them? Or can I get by with just installing the cam and leaving the lifters? Thanks in advance for any help.

Butch Back in the day we used to have our solid lifters re-ground. Had a convex face put on them. Downside is you still have to pull them and re-install. Pete

Butch: For my money I would change the lifters. I know that it's alot of work but according to the experts they have taken a "set" after twenty min's operation. Keep the old lifters in order and sell the cam and lifters as a set and you should be able to recoup your money. By the way what is the grind?

Hello, I realize I'm new here but I have built quite a few engines and if I can I would suggest that you keep the lifters with the cam they were with (and keep them in order with the lobes) and install new lifters with the new cam.

Bob Sorry to disagree but as many parts as I have bought used I WOULD NEVER BUY A USED CAM. How do you know where the used lifters were? And on a Yblock what about the hassel or re-install with the crank in place. Bad idea or REALLY BAD IDEA? You make the call. Pete

Glenn, The cam that is in the engine is a Lunati. I took the access plug from the rear of the block and found the grind number and Lunati couldn't find any information on the cam. Scott at Delta Cams told me the cam had duration of 249/258 @ .050 and lobe lift of .336/.339. I don't remember the lobe separation but I think it is 108. I am travelling this week and won't be able to go to the garage and look at the grind number again. The cam is just more aggressive than I want for a street car. Looking for more like an Isky E-4. I heard the engine run before I bought it and knew that the cam change was going to have to happen and will change the lifters too if I need to, was just hoping that I could get by with just changing the cam. If you think you might be interested in the cam/lifters send me a pm and I'll keep the lifters identified with the hole they came out of. But I warn you Lunati's young techs can't give you any info about older cams!!

Pete,
I agree! I would never buy a used cam either. I was looking at the other aspect  of the question, meaning I wouldn't put in a new cam with used lifters, even if they were reground. Sorry for the misunderstanding.
Then MAYBE sell the other cam set if it looks OK (he said it had about a thousand miles on it). That's why I suggested keeping the lifters sorted out.

Didn't realize that they ever had a Y Block cam. Send it to Mummert and he can put on the Cam Doctor and give you the specs. I don't need it, but someone on ebay will buy it. If the lobes are in good shape and the lifters are reinstalled in the proper order, there is nothing wrong with reusing it. I have rebuilt several engines over the years without replacing the cam or lifters. They just need to go back in the proper order.

Butch,
Sounds as if the engine is out of the car/truck. Shouldn't be to difficult to change out lifters when cam is out.

Glen: I don't know if Lunati had off the shelf cams for Ys, but I have one of his stock class "cheater" cams for my F code. He recommended I run it at .009 clearance, but set it to .015 for NHRA to check it. It checks dead on the factory spec at the .015 clearance, but is far too wild to check stock at .009. I doubt if NHRA would have allowed you to re-adjust the valves before they checked the cam. I was never checked with that cam in it.

John, I learn something new everyday on this site. We used to run Lunati"s in the scrub round track cars with good results, but would never have thought of them for a Y block cam.

Slightly off topic, but isn't Lunati a division of the Holley Corporation, which unfortunately just filed for Bankruptcy?

Well Holley has been in trouble for quite awhile, filing bankrupsy in February 2008 http://www.bloomberg.com/apps/news?pid=20601103&sid=aBsaKFQDcFqg&refer=news and again in October 2009.
And yes Paul, Lunati is a part of Holley.
Holley, Specialty Car-Parts Maker, Files Bankruptcy (Update2)
Share | Email | Print | A A A
By Steven Church
Feb. 11 2008(Bloomberg) -- Holley Performance Products Inc., a century-old maker of specialty parts for stock-car and drag- racing, filed for bankruptcy, faulting a late 1990s expansion for saddling the company with too much debt.
Closely held Holley would be taken over by noteholders owed as much as $145.8 million, according to an outline of a reorganization plan filed today in U.S. Bankruptcy Court in Wilmington, Delaware. The company, based in Bowling Green, Kentucky, listed debts of $243 million and assets of $106 million as of Jan. 28.
In the years following its expansion, ``Holley did not generate sufficient cash flows to support the debt incurred,'' Chief Financial Officer Thomas W. Tomlinson said in an affidavit.
Holley and four of its affiliates filed for bankruptcy protection about two years after the company renegotiated the terms on part of the 12.5 percent notes that were due last year. Holley's majority shareholder, funds managed by Kohlberg & Co., quit providing the company the cash it needed to make interest payments, according to court papers.
The reorganization will cut Holley's debt by about $100 million, Tomlinson said in a telephone interview today.
Holley has about 390 employees in Kentucky, California and Mississippi who make carburetor and other fuel and air-systems parts with brand names including Hooker, FlowTech and Nitrous Oxide Systems.
Nascar Sponsor
``Employees will not be affected by the bankruptcy, and the company will continue operations as normal,'' Tomlinson said.
Holley's customers include Ford Racing and GM Performance Parts. The company is a sponsor of the National Hot Rod Association and has a program that supports the National Association for Stock Car Auto Racing, (Nascar), according to court documents.
The company was founded in 1903 by brothers George and Earl Holley, who designed a carburetor for the Ford Model T called the Iron Pot. Later, Holley built engine parts for planes during World War II, according to the company's Web site.
Under a deal negotiated with 70 percent of the company's second-lien noteholders, Holley would pay its general unsecured creditors, such as trade vendors, in full and give almost all its equity to the noteholders, according to a description of the reorganization plan, called a disclosure statement, filed today.
Noteholders would get about 45.8 percent of what they're owed under the proposal, which requires a judge's approval.
The case is: In re Holley Performance Products Inc., 08-10256, U.S. Bankruptcy Court, District of Delaware (Wilmington).

I have rebuilt several engines over the years without replacing the cam or lifters. They just need to go back in the proper order.Take this as anecdotal. My mechanic was working over a BB chevy. The owner came up with a little used flat tappet cam, as verified by the mechanic's judgement and measurements. Do not remember if the lifters were also present from the cam. Isky was contacted and their guarded response was that the cam could be reused as represented, but recommended new lifters.

When I talked to the tech at Lunati he told me that the Lunati division had been sold by Holley to someone else prior to them taking bankruptcy.

For arguments sake... obviously if you have a good cam without the original lifters, new ones will be needed. However, if you have that same cam with the original lifters, that you are sure have been kept properly in order, why would you break in new lifters on that cam?

Paul, my thoughts also, don't make since to do otherwise.

If the cam and lifters are being reused in the same block, no issue as long as the lifters are kept to the lobes that they are matched to. When changing blocks, there’s always the chance that the lifter bores do not align the same from block to block which means the cam could still go bad with the original lifters as a new wear spot on the lifter is taking place. Just food for thought. My recommendation for used camshafts in blocks they were not originally run in is to always use new lifters in those instances.
