I only stayed with the 2 barrel as that's what the OP is doing. I believe that I even suggested the use of a truck 2 barrel carburetor and intake manifold plus the 360 2 barrel cam. I think that it's awesome to see how much power you can get without spending the big bucks
if you're deviating from a stock build, why would you spend the time, energy and money to hunt down parts that are categorically inferior?
replacing a 2bbl intake with another 2bbl intake? replacing a 2bbl cam with a different 2bbl cam?
madness.
a cheap *** split pattern RV cam is better in every conceivable way than a 2bbl 360 truck cam. a swap meet intake and carb or ****, even a 4bbl carb adapter and bottom barrel tiny 4bbl carb is leaps and bounds ahead of any 2bbl.
