Do you need to rebalance a Buick 231?
Technically, you need to rebalance a 231 if you replace the flywheel or install a flywheel in place of a flex plate. Some people report that they have had no problem swapping different flywheels on these later engines with out rebalancing. Later Buick 231s use multiport fuel injection.
What kind of fuel injection does a Buick 231 use?
Later Buick 231s use multiport fuel injection. The Buick V6s never used TBI fuel injection from the factory. Project Pieces & Parts Engine Installation : Project Pieces & Parts finally gets the fired up with a Buick 231 V6 sitting on engine mounts from Advanced Adapters.
When was the Buick 231 converted to even fire?
In mid-1977 the 231 was converted to “even-fire” (120 degree spaced firing impulses) by changing the crankshaft, camshaft, distributor and (presumably for increased volumetric efficiency) the cylinder heads and intake manifold. As such, interchange of these parts with earlier V6’s ranges from problematic to impossible.
Can a Buick V6 be swapped for a Dauntless 225?
The odd-fire design cause a the engine to idle a bit rough. This version of the engine and parts from these Jeeps can be used to swap a Buick V6 into your Jeep. One big advantage of the Dauntless 225 V6 is the heavy flywheels used on these engines. The flywheels come in 75lbs and 100lbs versions to create low end torque.
