Which 4bbl carb for a 65 273

I use a 500 cfm eddy on my 273 with 66 formula s 4bbl manifold [i swapped out the 2bbl] and i use a 1 inch phonolic spacer. Gonna have to modify your kickdown rod [extend it] and get an adaptor kit from eddy for the throttle linkage along with a taller intake mount for the throttle cable.
