I have a 67' 400 /4-speed. Stock set up, no headers. Still have the original throttle linkage and gas pedal set up, linked to original Rochester 4BBL (which installed an electric choke on). I am considering replacing the worn out linkage and pedal set up with a OER linkage or cable system. Strong opinions of which way to go and with what aftermarket products? My sense is that the cable set up will perform a bitter better but I do not want to waste money if not beneficial or necessary. Thanks.
