Composite Rockers

[1968galaxie]

From an old Yellow Bullet post several years ago regarding AWA composites:

"I sent them an email and the response: $1200 per con rod, $1500 per piston, $315 per pushrod, $595 per lifter pair and $500 per rocker.... Definently a solution for someone with deep pockets and or max effort build goals."

Not quite cost effective for most folks.

funny,i remember ford tried compost rods in there 4 cyl race engine,in the 80s and as you can guess it didnt go well! deep pockets are a must here

When the idea is to simply duplicate what has already been done, what's readily available is likely 'good enough.' When one is interested in moving boundaries, experimentation is demanded.

I remember around 1990 at Ford hearing about Polimotor  https://polimotor.com/ 

They were building a complete composite four cylinder race engine.  I remember seeing impressive pictures of engine explosions!  Usually all that was left of a failed crank was cotton candy in the block 

If you look at the website, they seem to have mostly given up on composite engine parts.  They are focusing more on metal 3D printing now.

Any notes on the weight savings?

I knew the guy pretty well who was the Ford end on the Polimotor project. He had personal demons and did not play well with others. When Polimotor finally delivered a functioning engine, FoMoCo said, in effect, "Thanks." He wasn't satisfied and raised such a ruckus he was ultimately terminated.

The engine ran just fine, and because the parts were so light weight, it would turn 13-14 K although relatively mild as far as cams-design etc.

The term composite is used too loosely.  A component that handles a substantial load (rods, rockers, etc) will have carbon fiber.  These are costly at the moment.    Intake manifolds, radiators, etc. will have glass or hemp fiber.  They are cheap.  The type of resin is selected based on temperature and tolerance requirements.
