i am putting a 4bbl on my poly and was wondering if anyone could tell me the specs for the 2bbl cam and if there was any difference in the 2bbl and 4bbl or dual quad cams?

1960 318 poly cam (others are probably similar):
Intake:
Lift - .370"
Duration - 244deg

Exhaust:
Lift - .368"
Duration - 244deg

The duration numbers came from the 1960 FSM which left out the lift. There was a four barrel cam in 1960 with 248 duration. The lift number came from National Service Data and list .390" lift for the four barrel motor. According to the 1964 FSM the two barrel motor had more lift than the 1960 four barrel motor.

We can supply you with a cam for your 318 Poly. Give us a call and ask for Dave if you are interested.

The 1957 Fury “V800” 290 hp cam #1825890: 256° duration; timing, intake: 22°-54°, exhaust: 60°-16°, 38° overlap, LSA (lobe separation angle) 109°, .405” lift.
