Hello I received some great responces for help with my c4 clutch issues. I am currently having problems with my 66 elcamino 327. On hot days while driving, i will experence power fade. It does not miss or cut out, just loses power. If i cut the ac and pedel a little it will pick back up and go in and out. Its mainly a stock motor with only headers. Nothing is new to the set up. It did it last summer also, but not during winter months. Thanks in adance for any adice.
