Really folks....I've been reading for days. My eyeballs are gettin sore

I was hoping Pat McCarthy would step in?

Does anyone think any of these remans would give me a good start on a big block build? I might add fuel injection much later as $'s come my way. For now I'm thinking about the 427 (love the revs) mated to a 700R4. Going in a 36 Chevy Lowcab Pickup. Max Hp less than 500 HP. I've kind of lost interest in the LS1/4L60E. Too much for me right now. Maybe next year. I need to get this thing rolling in the next 6 months (fingers crossed).

I assume one of these might have a steel crank. It was suggested by a friend to try to stay away from the tall decks? I assume that has to do with the shape (spark pattern?) of the combustion chambers. Oh.....I feel ignorant!

Does anyone know where I can cross reference these part numbers myself?
A local chevy mechanic?
