At what point in moding an engine would the clutch need to be replaced with a locking clutch because of excessive slipping? i have new pistons (66), milled carbes, dune port, and CPI pipes. now it does not seem to be to extreme i have heard of more being done. So at this point if i go with the hinson and get trinity plates will it last one or two seasons or will i still have this problem? Thanks for your input.
