^Yup, that's me
I’m looking for engine component weights for a forged ('68) 225 slant-6 in a quest of reducing reciprocating mass and inertia [list below] - and am starting with valve springs. Beehive springs are commonly available for LA engines - surely one must cross-fit to the 6 - right?
A piston changes its direction of travel twice for each full crank rotation, and in doing so comes to a complete stop (briefly) each time. Therefore, reducing inertia (weight) can have a seat-of-the-pants feel in terms of throttle input and drivability - at all RPM ranges - not just at the top-end (although that's most often what comes to mind). None of these concerns and componentry are exotic; they are commonplace in even modern economy cars - it's an exotic thought, however, to apply this ideology to a 50-year-old slant-6 engine.
That said, I’m on a quest to find low-inertia parts with an emphasis on selecting the lightest-weight components without a sacrifice in strength or longevity (the list will be short - I know). Not interested in titanium.
Below is a list of other lightweight parts I'm searching for with an emphasis on selecting the lightest weight components without a sacrifice in strength or longevity (the list will be short - I know). Not interested in titanium.
If you have knowledge to any of the weights to the parts below - please state the part, vendor, and weights in grams please. No bathroom scale weights Use this converting lbs to grams - Google Search to convert pounds to grams.
Thanks to all in advance!

- Intake Valves 1.70" (OS-dia) - lightest - possibly with smaller dia stem of 7-8mm.
- Exhaust Valves lightest 1.36" (STD-dia) - lightest - possibly with smaller dia stem like above
- Valve Spring Retainers - lightest - steel - possibly narrowed or drilled
- Pistons - lightest
- Piston Pins - lightest
- Piston Compression Rings - lightest - molly
- Piston Oil Rings - lowest tension (the odd-ball in the bunch)
- Push Rods - lightest
- Mechanical Tappets - lightest
- Harmonic Damper - lightest
- Connecting Rods - lightest
- Rod/Crank Bearings - lightest
- Connecting Rod Bolts - lightest
Thanks to all in advance!
