I am getting ready to get a used 1995 5.0L HO motor delivered monday, I have a 1000lb universal engine stand and I need to know what size bolts to use to bolt the block to the standplate, I was told by someone that they thought 7/16 coarse thread and 3" long would do it. I picked up 4 of them today and the length seems perfect but is the 7/16 coarse thread correct....Thanks Jim
