Recommendations - I found that buying aftermarket rod bolts, head bolts and main journal bolts were cheaper than buying from GM. I recommend that for none critical bolts like the valve covers or intake manifold bolts, you can use Grade 5 bolts. I used grade 8 bolts cause they are very inexpensive at bolt supply houses - about 1/10 the price versus buying a generic bolt at your local hardware store.

Important - For the flywheel, flexplate, torque convertor, head, main journal and especially the rod bolts, use bolts specially made for this application! Do NOT use bolts purchased at bolt supply houses or hardware stores. For example: rod bolts are specially made to stretch a specific amount during tightening and to flex while under load. If you want to read more on fasteners used in the automotive industry, I highly recommend Carrol Smith's Nuts, Bolts, Fasteners and Plumbing Handbook. It'll scare the bejeepers out of you when you realize the misuse of fasteners! It's a must read if you are monkeying around with a car like I am doing.

This is a must for anyone like myself who builds car parts from scratch. Carrol lends his decades of experience and insight to documenting the pros and cons of using almost every device used to hold something together on a car. The book is well worth the read and scary in some ways as you realize that maybe using duct tape to hold the tranny in place may not be such a good idea after all...
