Anyone have a clue as to what these parts are? The seem to be some type of Push Rod stabilizer is all I can think of. The engine is a Mondello built 508 Olds (455). May have been built in the 90's Lots of mods to the engine.

 

look like plastic guide plates for non-hardened pushrods.

 

Haven't been in touch with Mondello yet.. Would it be somthing theywould normally put in? and what do they do?

 

Those are Crane 36655 pushrod conversion guides. 5/16" stud on the bottom screws into the head, 3/8" stud on top for the rocker. Designed for an SBF but obviously also works on an Olds.

 

Thanks guys, have never seen them before.

BTW the engine is in a 1937 Businessman Coupe My brother picked it up about 15 years ago and he had a stroke and it had been stored in a unit for 10 years. I am just in the process of getting it back on the road.

Not really a Olds guy but I did remember Mondello from the old days ( Used to run at Lyons Drag strip in Wilmington, Ca in the early 60's) , he had a few rods that used to run pretty good as I remember.
