Updating my guesses also #4- 6 pak. I am also VERY interested in the outcome of this. My RPM seemed to have much more bottom end than the torker. I am dying to find out how the Offy Low rise dual quad performed. I love the looks of them and if it faired well just might look into buying one ! And 1ofnone I love the looks of your car too ! It looks killer, right out of a 60's magazine. Very,very NICE ,Dave.
