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.

If I was road racing or autocrossing, I might consider a lighter flywheel. But for a street car, I wouldn't bother.

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.

I used to have a very light flywheel on my 914 with the first revision of my 2056. It spun up really quick, but also spun down really quick. It was fun for short drives but it got old pretty quick on longer ones or if I got caught in traffic anywhere. When the engine came apart for Rev2 (its currently on Rev3) the light flywheel was replaced with a stock weight one (maybe a TAD lighter - I don't honestly remember). It made the car a lot more fun to drive IMO.
