If it was me, I would run the stock intake and carb.
I also would run the original 340 cam if it is in good condition
with new lifters.
These cars would run to 6000 easily with stock springs and camshaft
and were good daily drivers that would run 13s in quarter if well driven
and tuned!
My son and I both run NHRA legal stockers that run Mid 10s @ 125
with stock intake and carb plus stock lift intake = Nothing wrong with intake
and carb.
