stock 2bbl intake vs 4bbl intake...difference??
I have a 1970 429 w/ a stock 2bbl intake and carb..i picked up a stock 4bbl intake from the same year and was wondering what the difference and how much of a difference it would make if I swapped out the manifolds and added a 4bbl carb or just left on my 2bbl intake and got an adapter for my 4bbl carb to fit?? basically is it going to be worth the time it takes to swap out the manifolds or just get a 2 to 4 bbl adapter....thanks

a 2bbl 429 is rare they was rated at 320 hp the 429 4bbl was 360 hp if it was me i would put on the stock 4bbl intake with a 750 cfm carb and run 14 deg timeing. because stock is 5 deg make's alot more power at 14 deg do all that and you will have a tire bunner for sure i have done this before so i know what im talking about good luck.
