What the bolt size and pitch for the bellhousing to block bolts? I gotta put my 6L on the engine stand.

 

I need this as well..... so I can bolt my damn tranny to my 4.8L!

 

Here ya go. I quit being lazy and found my own answer..

Bellhousing to engine: M10x1.5x40, 13mm hex.
Tailhousing to transmission case: M10x1.5x27, 15mm hex.
Bellhousing to trans case: M10x1.5x45, T50IP (torx plus)

 

Thank you, they're the only bolts my supply place didn't carrry. They had the flywheel and clutch bolt packages, but couldn't spec those ones.
