Subject: Re: 4.5 litre pushrods
Hi
Agree with the above

Never ever seen a pushrod problem on a Meadows 4.5 that can be blamed on pushrod design.
Rockers seized, coil bind of the valve springs, collets hitting guides, pushrods hitting castings or head gasket etc will all caused pushrod issues, but pushrods themselves are immensely strong.
No other engine that I know uses anything even close.
Why “improve”
And certainly not by drilling oil holes thus allowing to fill with oil.
On many American v8 race engines you actually close these holes.

Hope this helps.
