small block adjustable push rods

Harley motorcycles run adjustable pushrods, but they are IMO, "extremely" robust for the application. Ok maybe not extremely, lol, but I don't think the Mopar adjustables would make it around the block,. IIRC the adjustable screw section is maybe 1/4"diameter, fairly long, and I doubt it is hardened....... I think it was just designed as a set-up tool. I sure wouldn't use it for anything else....... altho I too once thought about it... lol.
