Jeep Engine: Dauntless Buick 225 V6

Jeep Engines The "Dauntless" 225 V6 engine was introduced
in 1966 in the CJ and C101 models. The V6
configuration of the engine makes it very
287(4.7L) V8 compact which is a big plus in tight Jeep
360(5.9L) V8 engine compartments. Kaiser purchased the
318(5.2L) V8 tooling to build the 225 from Buick and
242(4.0L) I6 later, AMC sold the tooling back to Buick.
150(2.5L) I4
173(2.8L) V6 A desendent of this engine, the 231 (3.8L)
GM 151 I4 V6, is used in GM cars to this day. The
AMC 401 V8 modernized and common 231 is a good canidate
AMC 360 V8 for replacing a blown 225. There are
AMC 304 V8 differences in the balancing of the engine
AMC 258 I6 though, so it can be tricky. The 225 is
AMC 232 I6 externally balanced and the 231 is internally
"Dauntless" 350 V8 balanced. This means you cannot just throw
your 225 fly wheel on a 231, the 231 must be
"Dauntless" 225 V6 balanced.

"Vigilante" 327 V8 The flywheel itself used with the 225 is not
typical. The flywheels used in the Jeep
"Tornado" 230 I6 vehicles are very thick and heavy to increase
Perkins 192 I4 torque. The flywheels used in Buick cars are
"Hurricane" 226 I6 much lighter.

"Hurricane" 134 I4 Since the 225 is a Buick engine, it uses the
standard Buick bell housing. The standard
"Go Devil" 134 I4 Buick bell housing will bolt to a SM420, so
this is probably the best transmission swap
Engines option for Jeeps equipped with this engine.
The T-14 and T-86 3 speed transmissions used
Upgrades behind this engine are not known for their
Factory Options strength.
General
The Buick 225 uses a cast iron block and
cylinder heads with mechanical lifters and 3
main bearings.
