2 barrel , 4 barrel, whose got the answer?
Stick with the 2bbl . The throttle pressure for a 2bbl will be easy hook up. 4bbl without parts will be a nightmare. Just a thought for the transition to go smooth
I agree. at the minimum, the following parts are needed;
the 4bbl intake. If you have A/C that will need to be addressed.
the gaskets, sealers, etc. and a 4bbl choke
Likely the Valve Covers will need to be removed, so more gaskets.
the 4bbl throttle bracket,
the 4bbl front KD rod, and
the 4bbl throttle cable. PLUS
the 4bbl air-filter housing, with filter. and
a new fabricated hard fuel-line down to the pump.
And maybe some hardware.
and maybe an oil/filter change afterwards.
Some of this stuff can be fudged, but if you do it wrong;
what if the throttle sticks at WOT, then what?
Or if the KD does not function correctly and the trans burns up, then what?
I agree that the LB carb is lean. and they are PITA to get working half-decent, therefore;
I agree with swapping to an older carb.
