Mike, Do you also make headers for a FE428 eng and will they fit FFR 4in4 sidepipes? If so how much. Also a question,I have heard not to use the std 5.0 clutch cable setup but a hyd clutch setup on the FE motors. Is it too much clutch for cable? I am using a tremec TKO tranny and had planned on using a cable setup and would like to if its durable enough or would I need to keep an extra clutch cable in the trunk. Thanks, Glenn,FFR1990.
