need to know what size the bolts are to fasten the clutch to the flywheel for a 3800 i have the steel camero flywheel, I would like to get new grade 9 bolts size???

Did you ever get an answer to this? I need to know as well.

i just ordered part number 234-1001 (x3) from summit to button my FW up. other disaster stories i read on here from not using the right bolt type scared me. dont wanna have a bad end result like i saw from most of these other guys.

After this amount of time, did the bolts work out for you. Summit's a couple blocks away, and this would be a convenient solution. What torque specs did you use?

Just an FYI for everyone, I ordered the ARP 234-1001 kit (3 sets of 3) after calling ARP. Tech support at ARP recommends between 26 and 26 FT/Lbs with red locktite.

hope this helps!

For mounting a manual transmission flywheel to the crankshaft on a 3800 Series 2 or 3 engine, you need 8x GM p/n 24505092 flywheel bolts. Torque to 11 ft/lbs + 50 deg turn.

The ARP Tech we talked to about the ARP bolts said they were NOT designed for 3800 flywheel to crankshaft mounting duty and he could not recommend them as such; further stating they weren't even as strong as the factory Grade L9 bolts GM sells for this application.

For clutch pressure plate to flywheel mounting, you'll need six 8mm x 1.25 grade 10.9 metric bolts (20mm length should be what you need - just make sure the bolts don't protrude out the other side of the flywheel where they can rub or hit the engine block).

That's not what the ARP tech told me, he assured me the ARP 234-1001 would be up to the task.

I agree that given the option, I would prefer the GM bolts designed for this purpose. However, some of us are having interference problems. There was confusion over the actual torque values, I called ARP and posted my findings to help others in the same situation.

Is the company ARP itself, willing to guarantee that statement and fix any failures and damages that are the result of using the 234-1001 bolts for this task if they fail?

My problem is one day we talk to one tech at ARP that says under no circumstances that the ARP bolts made for a SBC cam sprocket should ever be used to hold a flywheel onto the crank of a 3800. And another day you talk to a different tech that says it is ok. Who do we believe?

I've never had a problem with interference with the GM flywheel bolts. Anyone that has is either trying to use mix-matched parts, incorrectly installing the clutch disc, or is trying to use unproven clutch components with the 3800. I've installed at least half a dozen 3800 SC engines into Fieros that had manual transmissions and never had an issue with OE GM flywheel to crank bolts breaking or interfering with the clutch disc or any clutch component.
