    Installed the new Howard's cam and hydraulic lifters. Broke them in per cam manufacturer instructions. Have about 500 miles on it. After sitting overnight, all the lifters rattle about 1 or 2 seconds at startup. Then everything quiets down. Is it just the stiffer valve springs collapsing the hydraulic lifters? It is 351 cleveland.stock rockers, pushrods, and valves.

    Get rid of the Fram filter.

    Actually I used a Napa filter. The engine is in my 1955 tbird, and the steering gearbox is so close to the engine, I have to use a filter for a Renault of some kind. It's only 2" or so thick!. I think it has the check valve in it, not sure. Thanks for the info, that may be the problem.

    My '63 Tbird (390) did that on startup all the time.

    The Renault filter likely is the issue. Probably doesn't have a residual pressure valve. There is a really small Ford filter that may work. I think Crown Vic police package with a 351w but I'm not sure.

    I had to get the Fram dig in, though. I see way too many similar issues when someone uses them.

    Cleveland’s are known for noisy valve train. I had one that I put new lifters, rockers and pushrods in and it still clatters. Did some research and apparently some of them have oil pressure issues to the Lifters on the back passenger cylinders.

    You might try a 90 degree or a remote oil filter adapter, that way you can use a full size filter.
