Thoughts on lightened flywheels and clutch disks, For performance motor Options

[Boomingbeetle]

I have a 2270 motor that I will eventually be putting into my '71 with a sideshift tranny, once I get some dress-up and parts collected. It does not currently have a flywheel, clutch, or pressure plate.

1. Is there a benefit to finding a lightened flywheel if the motor has lighter internals?

2. I assume I should use a 6-spring clutch disk or an aftermarket performance material, but maybe this isn't necessary for a 150-HP/TQ motor? Ditto for the pressure plate.

Hold on, everyone here has a 914 because they like to DRIVE, right? If you want a well behaved street car, you get a Camry. Snappy engine response is one of the things that makes shifting a joy. Maybe the stock flywheel gives you what you want, but it is at least something to think about.

This IS, in fact, the only noticeable difference a driver will "feel" with a lightened rotating assembly is throttle response when the car is out of gear (again - as compared to removing the weight from anywhere else on the car)

Well, exactly, which is what happens every time you shift. As you move from one gear to the other, in some situations you use the throttle to get a certain RPM before engaging the next gear. Faster response gets you back in gear faster.
