3.4 Bellhousing bolts size?
Picked up a harbor freight 1 ton engine stand and want to load my 3.4 block onto it to work on it but I have no bolts. Can someone confirm size? I did some digging and came up with this.... m12 x 1.75 x 90mm .. ? Do they have to be longer to go thru engine stand? Thanks.

Re: 3.4 Bellhousing bolts size?
You're definitely going to need longer bolts. How long depends on the engine stand. You'll have to get the stand, measure where the bolt goes through and then add a bit to make sure you have enough to thread into the block far enough to properly support it. Get a Grade 8 bolt too, not some cheap ones. Here's what I've done, buy a bolt that threads in the block, see how far it threads in and measure the portion of the bolt that is threaded in the block. Then measure how thick the engine stand mounting is and add those together, that's how long of a bolt you'll need, x4.
