I had a book laying around that gave you everything you needed to know on how to tell the difference between what CI block you might have, but I can't seem to find it. I need to know where/what to look for on my Big Block to verify it is indeed a 454(Truck came OE with a 350, so it is not original)

It isn't running right either. Doesn't seem to have much low end, and it will hesitate some while driving when you get on it and backfire out the exhaust once and awhile without warning. The pervious owner put an Edelbrock on it, and it may need tweaked some, but I have a gut feeling it is ignition timing. I don't have a BBC book, so does anyone have the spec's?

TIA,
TP
