Thread size for tranny bellhousing to engine block bolts?

[DemonDave]

I bought an engine stand today to mount my 360 engine so I can work on it over the winter. In order the hang the engine, I need 4 bolts that will thread into the engine block that are about 1 1/4" longer than the bolts that are normally used to bolt on the tranny. Anyone know what the bolt diameter and thread pitch is for this? It would make my life a lot easier when it comes time to buy them.

Thanks!

PS: I don't have the bolts to mount the tranny yet so unfortunately, I can't just take the old bolts with me to match them up.

all mopar bellhousing bolts are 3/8-16 .

3/8-16 nc is correct. Stack a couple flat washers behind their 9/16 hex heads or they will bury into the tubes on the stand.
