Its {{convert|161.1|cuin|cc|0|abbr=on}} displacement features a compression ratio of 7.6:1.<ref name="ruralwillys">{{cite web |url= http://ruralwillys.tripod.com/diversos/motoreswillys.htm |title=Motores Willys 6 cilindros: BF-161, 2600, 3000 + Ford 4 cil.

'''2600'''
The 2600 was the same BF-161 engine made in Brazil by Willys-Overland's subsidiary, but it had two one-barrel carburetors (simultaneously opened) and had an output of {{convert|130|hp|kW PS|0|abbr=on}} at 4400&nbsp;rpm and {{convert|140|lb.ft|N·m|0|abbr=on}} of torque at 2000&nbsp;rpm. The compression ratio remained 7.6:1.<ref name="ruralwillys"/>

'''3000'''
The 3&nbsp;L version is almost identical to the BF-161 engine, with the stroke increased to {{convert|4|in|mm|1}}, giving it a displacement of {{convert|3016.5|cc|cuin|1|abbr=on}}.<ref name="ruralwillys"/> With a two-barrel carburetor, it produced {{convert|140|hp|kW PS|0|abbr=on}} at 4400&nbsp;rpm and {{convert|161|lb.ft|N·m|0|abbr=on}} of torque at 2000&nbsp;rpm. It also had a slightly higher compression ratio of 8:1.<ref name="ruralwillys"/> It initially used a different head with a removable intake manifold. 

After Ford acquired Willys-Overland do Brasil, they reverted the engine to its former head design with an integral intake manifold. Ford also improved the cooling between cylinders 5 and 6 as well as incorporating a side-mounted oil filter instead of the front-mounted, hose-connected system designed by Willys.
