a stock motor.
The 38mm DGAS carb should be the only consideration if the engine
is in the future or currently going to have any level of additional engine
modification. Such as headers, free flowing exhaust, a cam, or rebuilt
engine. Usually these motors will be improved over stock with oversize

carburetor in some situations. There is a performance jet kit just for the
Jeep applications Pt No. 701-DGV.

It also provides the best starting point for engines that are ultimately going to be upgraded with additional performance Items with performance over fuel economy being the ultimate goal.
