Stop in for a cup of coffee

Swapping the /6 for the V8 ... plan was to put the proper accelerator pedal in. But then I figured out that that pedal that is in here now is a mid-70s setup... so anyone's guess at this point. All I have to go off of is the parts book, body book and assembly manual.
Or go all hot rod and build your own? Wilwood has a great modular kit? It even comes with a three pedal option!
