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. |

I've been building engines close to 30 years my personal T4 performance engine is 2600cc 180 HP (more details in my signature) summer daily driven.
My flywheel, pressure plate and disc (6 spring, both were new Sachs) is basically stock with a .010 undercut on the fly for a bit extra clamping pressure. Really, at your power level, you don't need anything more and a lightened fly will just be a PITA on the highway. |
