Rear Disc conversion super noisy?

I am using the stock master cylinder for manual brakes and it stops great, yes I did remove the stock retainer plate, I am pretty sure you have to. I bought a universal Lokar e brake kit from Summit that worked great but you have to get creative with the right side cable because it was still too short, I added a piece of cable from the left side to get the right length. I will take some pics when I get a chance. The Right Stuff guys are the best to deal with for sure. Ditch the big block idea and build you a nice 408ci 360. You dont need the extra weight or the lack of room in the engine compartment.
