ENGINE SELECTION

or clutch components will need to be adjusted.
NOTE: LT1, LT4, ZZ4, and LS1 blocks all use angle port heads which is not compatible with our headers. These blocks also require
a steam release port on the radiator. The radiators we offer do not have the steam release provision.
We do not recommend the installation of Generation III Vortec engines for Toyota Trucks. The narrowest exhaust we could find is
25”, and the Toyota frame rail is 23”. The height and width of this engine is too large for a good, clean fit.
CHEVY V6 BLOCKS:
This block can either be the 3.8 (229) or 4.3 V6. These engines are identical to the Chevy V8 application with reference to the
bellhousing, starter, and flywheel. The oil pan has year differences as the Chevy V8. The 1996 & newer 4.3 blocks use an aluminum
oil pan. Vehicles requiring oil pan modifications using this block are not recommended.
Motor mounts are also the same as the Chevy V8, with the exception of the location of the triangular bolt pattern in reference to the
back of the block. The mount location on the V6 is approximately 4-1/2” closer to the backside of the block than on the V8.
The Chevy V6 is an excellent choice for a engine upgrade in Toyota vehicles. This engine offers a substantial power increase over
the stock 4 cylinder and is easier on your stock drivetrain when utilizing your original manual transmission.
BUICK V6 BLOCKS:
The Buicks used two different bolt patterns. The 225, 231 and 3.8L (rear wheel drive vehicle) all used the standard Buick bolt pattern
for which we offer adapters, motor mounts, and headers. Engine blocks like the 3.8L transverse (front wheel drive vehicle) have
the same bolt pattern as the Chevy 2.8L V6. We do not offer any conversion components for these blocks. We get many requests
to use the Buick 215 block; however, we do not offer adapters or motor mounts for the aluminum 215 block.
The Buick V6 provides an easy installation because of its size and nice fit into the Toyota 4WDs. The popularity of this conversions
has declined in recent years due to popularity of Chevy V6 and V8 engine conversions.
FORD V8 BLOCKS:
Ford conversions are becoming more popular. We do not offer any adapters to retain the stock 5 speed
transmission in these conversions. We do, however, manufacture numerous adapters to couple Ford
transmissions to your stock Toyota transfer case.
When selecting a Ford block, take the following information into consideration: Ford blocks used three
different block bolt patterns. We only offer motor mounts and adapters for the small block Ford 289, 302,
and 351W; the Ford 302 being the most commonly used block for conversions.
Small block Fords had the option of utilizing two different flywheel diameters. These flywheels can be identified
by a tooth count of 157 tooth or 164 tooth. It is critical that you match the flywheel diameter with the proper
bellhousing and dust cover shield. For example: A bellhousing designed for a 164 tooth
flywheel cannot use a 157 tooth flywheel. Since the starter bolts and indexes directly onto the
stock bellhousing, the starter would not properly engage the incorrect flywheel. Therefore, make sure you
verify the compatibility of these components.
When obtaining your flywheel, you must also verify that the flywheel has the proper balance. Blocks 1982
& newer used a different weight for balancing than the earlier blocks. Some applications may require
the flywheel to be rebalanced for the block.
When purchasing a Ford bellhousing, you should also consider your vehicle stock clutch linkage. Shown on this page are the two
different Ford bellhousings having different provisions for clutch linkages. Ford used various hydraulic and mechanical linkages.
