My son has a '67 Chevy truck he has restored. When the engine was over hauled, the alternator bracket hole in the intake near the thermostat was stripped out. This is a 327 small block with the aluminum GM intake. Is there anyway we can repair the threads or fix this problem. Thanks!!

You can install a heli-coil. Easy repair and stronger than origonal.You can pick up a heli-coil kit at most any parts house.

Ditto on the heli-coil.

Check out something called a "Time Sert" You will like them much better than a Heli coil.

I'm not sure what a time sert is but there is a keensert. A keensert is more heavy duty and requires a larger hole to be drilled. A heli coil takes up less space.

All good suggestions. Basically supv26 the helicoil is a spring-like insert. The other options are a threaded insert with keepers to prevent the insert from pulling out. Personally I'd go with a helicoil first and then upgrade if needed since the other methods require a larger hole. The old measure twice and cut once approach so to speak.

The reason I like time serts over heli coils is because heli coils are NOT designed to be installed where the fastener is going to be removed from time to time. The heli coils are perfect for a fastener that is to be installed and not removed (well maybe once) A time sert is designed to be used over and over like the original threads. I have used them in all kinds of places and have never had a problem. I have even used them in blocks where the head bolts go, and spark plug thread repair. [img]graemlins/thumbsup.gif[/img]
