Borg & Beck Pressure Plate Springs

No it's a 318. My car originally had a 273 but the block cracked and I just put a stock 318 in it. I changed pressure plates when I did the swap then pulled it back out again because the clutch was extremely stiff, popped that twangy spring sound when I depressed the pedal and was VERY difficult to disengage after I ran it on the highway. This is not a high performance car, but thought it could benefit from a little larger diameter clutch.

I'm not very happy with Brewers either because part of my disengagement issue was the clutch disk they sold me was .355 thick and I had to pull the tranny to swap in a thinner clutch disk. I could not get it to release with the adjustment nut all the way to the end, so I had to pull the PP again and swap the disk. I'm trying to stay positive here but I'm frustrated these shops like Brewers should know a stock clutch disk is only .305 thick.
