Hi-Performance 2F & 3F Engines
At Man-A-Fre, we offer the
highest quality, highest power output, rebuilt 2F and 3F engines available
for your Land Cruiser. These engines are balanced, blueprinted, and
hand assembled featuring our exclusive forged hi-compression pistons
with Deves piston rings, and Billet camshafts*. There is no other 2F
or 3F on the market that can match our power output, fuel economy, or
reliability when used with similar induction, ignition, and exhaust
systems. Our goal in building these engines is to supply an engine with
the broadest possible power band specifically suited to the type of
driving done in a Land Cruiser, while still running on pump gas with
increased fuel economy, and reliability. Man-A-Fre Hi-Performance engines
deliver massive low-end torque coupled with an ability to accelerate
that will leave you wondering if you still have a 6 cylinder under the
hood. So if you're planning on hauling heavy loads, towing, doing heavy
off-roading, want to easily pull freeway speeds, or simply want the
best running 2F or 3F engine available for your Land Cruiser, these
are the engines you are looking for. Engine blocks, cylinder heads,
crankshafts, connecting rods and appropriate parts are hot tanked in
an acid bath to remove most sludge, and debris. They are then baked
to dry any residual unwanted materials. After drying comes shot peening
to remove dried material, aid in inspecting for cracks, and relieve
stress. Cylinders are bored and honed by a machine that uses the crankshaft
bore for mounting, and alignment, thus assuring cylinders are perfectly
round and exactly perpendicular to the crankshaft center line, unlike
machines that use the top of the block for alignment, which allows irregularities
in the block surface to be translated into irregularities in bore alignment.
This precise alignment reduces friction and vibrations in your engine,
and promotes better ring sealing and longer ring life. Crankshafts are
magnifluxed, checked for straightness, ground and polished to Toyota
specs, then balanced with resized connecting rods, pistons, pins, rings,
flywheel**, and front pulley.*** All lifters, oil pump, freeze plugs,
rod bearings, main bearings and camshaft bearings are replaced. Cylinder
heads are magnifluxed, surfaced, and have all valve guides replaced.
Valve seat grinders in common use can yield rough, imprecise valve seats
leading to poor sealing and a relative loss in performance and economy.
Specialized machinery that uses 5 carbide blades to precisely cut seats
to three angles is used, yielding a smooth precise seat surface for
optimum sealing. Valves are matched to individual seats, and tested
with a device that measures each ports vacuum holding ability. There
is simply no other engine you can buy that has the features, and the
attention to detail as these. Engines are sold F.O.B. Simi Valley, CA
on an exchange basis. 3F engine cores are in limited supply, call for
availability. Core charge refunded only after tear down and inspection,
and block, crankshaft, and cylinder head are found to be rebuild able.
Engine core must be of same type purchased. We highly recommend the
use of one of our engine oil cooler kits with these engines. Compression
ratio for 2F is 9.0:1, and 9.2:1 for 3F. We do not build F engines due
to inadequate oil flow design. Engines are warranted against defects
in materials, and workmanship for 12 months, or 12,000 miles. Use of
Premium grade fuel required.
*Billet camshaft available for 2F
versions only.
**Flywheel not included in cost of
engine, if customer cannot supply, MAN-A-FRE will supply at additional
cost.
***Front pulley not included in cost of
engine, if customer cannot supply, MAN-A-FRE will supply at additional
cost.
Disclaimer: These parts
are designed for racing and off-road use only. They are not intended for
use in lieu of factory emission control devices, and they are not legal
for sale or use in California on pollution controlled vehicles.
**Price is for long block engine assemly only. Manifolds and other
accessories are not included.**
