I’ve spent half the day searching and reading for clutch recommendations. And so far I have not gotten a good idea for what to use. I’ve read a lot for applications on the L28 and they seem to like the Act and Centerforce clutches. I’m running a 305 out of an ’85 Camaro with a matching T5 and a light weight flywheel. I put a new oem replacement clutch in broke it in proper, but it is slipping with the extra hp. The 305 is beefed up and I thought an oem clutch would still hold up sense the 280z is lighter than the Camaro, I was wrong. I have not been able to dyno it because of the slipping clutch so I’m not sure what kind of numbers I’m putting down, but it should not be too outrageous, it’s only a 305. But I am planning on adding a 150 shot latter. So what are you running with how much power?
