Chrysler Big Block GM Adapter Kit Instructions

If you are not familiar with this type of installation, you may want to consult a Service Trade Manual. The manual will also provide you a complete listing of torque specifications. Your Chrysler starter will bolt into place without any modifications. You will need to modify the transmission bellhousing to gain needed clearance for the starter nose.

Step 1 Bolt adaptor plate to engine using bolts provided with kit (Four 3/8" x 15 x ū" Flat Head Socket Cap Screws, Two 7/16"
- 14 x 2" Flat Head Socket Cap Screws and Two 7/16" x 14 Nylon Lock Nuts).
Step 2 Install flywheel and aluminum crank adapter:
149260 and 149265: Use six 7/16" - 20 socket cap screws, use thread sealer and torque to 55 foot pounds
149280 and 149285: Use eight 1/2" - 20 socket cap screws, use thread sealer and torque to 70 foot pounds
Step 3 Install Starter using the studs and nuts on adapter plate. Check starter for proper alignment with the Flywheel teeth.
Step 4 Transmission Bellhousing Modification: The transmission will need to be modified for starter clearance. Fit the transmission (without the converter installed) to the adaptor plate. Mark the area to be clearanced then use a saw or grinder to remove material. Note: Remove only the amount necessary for clearance. Deburr, smooth and radius all corners and clean thoroughly after you have obtained proper clearance.
