Thanks... I went with the Mcleod Street Extreme kit
http://www.mcleodracing.com/index.ph...lutch-kit.html
It is supposed to be good for up to 700 ft lbs. The RST twin was considered but with the new required flywheel it was going to be almost twice the money this setup cost.
I'm just hoping this is halfway street compliant...not like an on off switch. Also hoping it lasts longer than a year. I did find it interesting that the pressure plate that came with this kit has the exact same part number as the pressure plate that came with the RAM kit that I put in last year. The way I understand it, there is only one company that makes replacement PPs for the LT1 style clutch kits and everyone that sells an LT1 clutch kit uses them.
