hey there, nice 74'. I just got one this summer! Its a 318 and I recently ran into a throttle linkage problem (mainly why I joined this site). The original kickdown throttle bracket for the 318 Mopar doesn't sit well with this dual port Offenhauser intake manifold I put in. What intake manifold and carb set up did you go with on your 74 Challenger?
Hopefully you'll be back on sometime soon!
