12\" vs 11\" clutch? opinions on what I should use? I have an 11" clutch disc and pressure plate right now in my K5. It came with a 305 and an 11" setup and when I swapped in the 350 I put on a zoom 11" pressure plate and a new autozone 11" disc. Now I am going to put in yet another engine but this time it will be a brand new rebuilt 355 with slight cam. I want to know should I spend the money and put in the 12" clutch setup? If so do you know where i can get a full setup for a reasonable price? I mean pressure plate, clutch disc, and throwout bearing for like under $120. I haven't checked how much it is at autozone yet but I know the centerforces are more then I care to spend, I know they are great and all but I just don't want to spend $300.
