ENGINE CONVERSION INFORMATION

P/N 717011
Left photo is P/N 717054.
Right photo shows the
tight clearance on the
717056 header with our
bellhousing. A muffler
shop can fit the exhaust
by the slave cylinder and
fork, but it is a tight fit. A
heat shield should be
made to protect the slave
cylinder.
H. EXHAUST HEADERS / STOCK MANIFOLDS:
On most conversions, you will have the option of using a custom exhaust header or stock manifold.
If headers are to be used, you will need to verify your State’s emission requirements since the
headers we supply are not smog legal. The following conversion headers are for V6 & V8 blocks.
Our headers are designed around conversions using our motor mounts. Due to vehicle
variations, some modifications may be required when using our exhaust header systems.
These headers are available in chrome or Non-plated (NP).
P/N 717056
P/N 717011 - Chevy V8 center dump headers (vehicles 1979-85 only)
*P/N 717053 - Chevy V8 rear dump manifold style headers (for vehicles replacing a stock V6)
*P/N 717054 - Chevy V8 rear dump manifold style headers (for vehicles replacing a 4 cylinder)
P/N 717056 - Chevy 4.3 V6 headers (vehicles 1979 & up) (Manual trannys require clutch arm mods.)
*P/N 717041 - Buick V6 headers (vehicles 1979 & up)
P/N 717012 - Ford V8 center dump headers (vehicles 1979-85 only)
*P/N 717044 - Ford V8 rear dump manifold style headers (vehicles 1979 & up)
*Headers will have interference problems with the release arm when used with a manual transmission.
Smog legal vehicles will normally require you to retain the stock manifolds. On GM V8 installations,
the stock manifolds from a 1982 & newer low performance car engine
work the best. These manifolds can normally be installed without any
modifications. For Chevy V6 installations, the manifolds from a 1985 Chevy full size truck
are an option. You can also try manifolds off of a 1980 Monte Carlo equipped with a
3.8 V6. On Ford V8 conversions, the early Maverick manifolds work well; however, they
do not have smog connections. We have been told that the exhaust manifolds from a V8 Ford
Explorer will fit with only minor modifications required. On the Buick V6, manifold #25507801 and
#1250528 should be used.
NOTE: All of the stock manifolds suggested above were obtained from customers that have completed the various conversions.
We have not personally verified the fit of these manifolds into these Toyota conversions.
I. FUEL PUMP:
A carbureted block can have fuel supplied to the new engine in two ways: an electric fuel pump or a mechanical fuel pump. The
mechanical pump is normally part of the engine and, at times, does create some clearance problems. When a mechanical pump
cannot be used, the alternative is an electric pump. Most carbureted blocks require a fuel pressure rating of 5 to 7 PSI.
Fuel injected blocks require a higher fuel pressure. These blocks can use the stock fuel pump that your vehicle was equipped with,
provided it has the correct PSI rating to match your engine. If this is not an option, you can install an in-line fuel pump with the correct
PSI rating to match your block. This pump should be added slightly ahead of the fuel tank. When using an aftermarket electric fuel
pump, you should also incorporate a safety circuit to turn off the fuel pump if the engine were to stall.
Whether your new engine is carbureted or fuel injected, and you use either a mechanical or aftermarket electric fuel pump, the stock
fuel pump located in the fuel tank should not have to be removed.
J. ALTERNATOR:
When replacing a 4 cylinder or V6 engine, we recommend that you purchase a new V8 alternator with an internal regulator to provide
better charging to your electrical system. When wiring the new alternator, you must remove the original Toyota regulator.
GM Alternator Bracket GM #14081227 (Adjuster)
GM Alternator Bracket GM #14015533 (Front Bracket)
GM Alternator Bracket GM #6262934 (Spacer)
If you elect to use the GM alternator that is equipped with a built in regulator, you will need to change the wiring. Remove the existing
Toyota regulator and cut the wires that feed the regulator. These wires will be the source of power to your new GM alternator. The
