#1: 6.5 power valve
#2: change only if manifold vacuum is below 9"Hg
#3: plain spring (try long yellow spring)
#4: Buy spring kit and tune carb
#5: Holley shows a # 50 jet as stock
#6: With the carb mounted sideways you may
encounter a lean condition during hard
acceleration due to the front jet becoming
uncovered due to fuel slosh. Engine may die
during hard stops also.
