What size bolts for 292 heads and bellhousing? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hi. This info seems oddly hard to come by. I just acquired a 292, out of a 68 c10 I think. It is sitting in the bed of a parts truck currently. I need to first hook it up to the engine hoist, sounds like by the head bolts is the way to go. Sounds like purchase some slightly longer grade 8 bolts to hook up the chains - what size bolts do I need to purchase?

Second, need to mount onto engine stand. As far as I can tell, I need 3/8 coarse thread bolts? Can someone confirm for me? Thanks!

3/8" NC for the bell housing

Not 100%, but believe 7/16" NC for the head bolts

Thanks. Seems like the head bolts are 1/2 by 4". Just bought some 1/2 by 5", so will confirm when I try and thread them in.
