kit and have it completely bolted
together, you must be able to pull
the torque converter assembly
forward towards the engine at
least 1/16" to 1/8". This prevents
any possible damage to the transmission pump. If this cannot be
obtained, please call our technical department for help. The bolts
in the kits for the torque converter are both metric and standard, please identify and use the
proper bolts for your torque converter.

FORD SMALL BLOCK 302 TO
CHEVY AUTOMA TIC TRANSMISSIONS
These kits are designed to fit Ford small block 302 to GM automatics ONLY. Please read the following
instructions before you begin to assemble.
INSTALLATION INSTRUCTIONS:
1. Remove the stock Ford
dowel pins and shorten
approximately 1/8".
The stock dowel pins
need to be flush with
the new adapter plate.
p
2. Install the stock
Ford 302 dust cover
shield. This shield
provides the proper
index and location
for the Ford starter.
r
Engine dowel pin
hole (backside of
block)
Dowel pin after shortenend
approximately 1/8".
3. Install the new flexplate to the block. The recommended
torque specification is 75-85 ft./lbs.
4. Install the new adapter plate to the block. Fasten the block
using the F.H.C.S.
5. "Check fit" the torque converter adapter ring on the motor
for the proper crank index. It should be a "slip-fit". DO NOT
FORCE THE TWO TOGETHER. Some older crank shafts
may need to be deburred as necessary.
SPECIAL NOTE: The components packaged in this kit have been assembled and machined for specific type of conversions. Modifications to any of the components
will void any possible warranty or return privileges. If you do not fully understand modifications or changes that will be required to complete your conversion, we strongly

normally available at automotive dealerships and parts stores.

6. "Check fit" the torque converter adapter ring on the GM torque converter for full engagement. The flat surface of the ring must
lay flat against the bolt surfaces of the torque converter. Some older torque converters may need to be deburred on the index
hub.
7. Bolt the torque converter adapter ring to the torque converter with the three (3) bolts supplied. The recommended torque
specification is 35 ft./lbs.
C4 automatic starter
8. Install the starter, making sure that the proper index is accomplished. The starter must be for a Ford small block automatic
transmission application ONLY! If a starter for a manual transmission is used, the Bendix will not achieve proper contact
on the flexplate. Ford starters from small blocks and these transmission C4, C6, AOD, AODE, 4R70W are all the same.

9. Slide the new torque converter assembly into the transmission, making sure that it is fully engaged with the cogs on the pump.
The transmission should now be prepped for final installation.
10. It's now time to install the transmission assembly to the back of the block. DO NOT FORCE. Once the GM transmission is
connected to the Ford block, the bolt torque specification of 35 ft./lbs. is recommended. The torque converter assembly should
have at least a 1/16" to 1/8" gap between the torque converter ring and the Ford flexplate. The torque converter must be slid
forward to meet the flexplate. This will allow proper clearance on the GM transmission to prevent pump damage. If the torque
converter is not able to move forward or it is preventing the transmission to be bolted flush to the adapter plate, check the
engagement between the torque converter and the transmission. This area is often overlooked (Refer to Page 5 for
measurements). If the torque converter is able to move 1/16" to 1/8", install the bolts to couple the torque ring to the flexplate.
11. Make the necessary modifications to the new plastic dust cover and install.
Trim off approximately 1/4" to 1/2".
