I have a 250 chevy engine that has powered a sawmill for years that needs an overhaul. A friend can bore it for me but he doesn't have a torque plate for the six. He would do it for free and he says not having a torque plate would not matter for the six. Does it matter? Getting it bored by the local shop is a little over a hundred bucks and I wouldn' mind spending it if it matters, but I can always use a hundred bucks if it doesn't. For example, I could buy some rotors for a brake conversion... Let me know what you think about the torque plate.
Thanks!

If you are just going to rebuild it and put it back in the sawmill I doubt that boring the engine with or without torque plates installed would make much difference one way or the other.

Thats two votes saying don't worry.

Rick In VA | | | | | Joined: Sep 2003 Posts: 2,384 Shop Shark | | Shop Shark Joined: Sep 2003 Posts: 2,384 | I will add another vote, I worked @machine shop, the torque plate was an extra charge usually reserved for race engines. They are a fairly new idea, many engines have run many miles bored the old fashioned way.

On old flathead fords we used a plate slightly thicker than the longer studs. It was counterbored so the head nuts would screw down on the studs lower than the top surface. This gave a flat surface for the boring bar without having to pull out 42 or 48 of those #^*$@ studs that always had a few twist off.
