350 Engine Bracket Bolt Size?

[Joe Kitzmiller]

What size (length, thread, diameter) bolt is needed for the engine mounting bracket on a 76' GM 350 block ? To make a long story short, I work out of town and rebuild my blazer on the weekends so i didn't get to check on what size is needed. Would like to know, so I can pick up bolts at Fastenal before going back home.
After next weekend it's been a little over a year since starting to restore my 73' k5 and almost everything mechanically will be rebuilt or brand new. Thanks - Joe.

There are a lot of brackets on a chevy engine. I would say the most common bolt size for a bracket that bolts to the engine block would be a 3/8'x 1" course thread. Some accessories (like altenator P/S pump) use a metric bolt to bolt them to the bracket itself.
