Hi,
The first thing to look for is caps on the u-joints instead of straps, rear sway bar, 7 leaf springs instead of 9. Then the tach redline (but that can differ from high perf small blocks too) of course there's the console data plate (can be changed easily) then depending on what big block it might have been- the fuel line, 3/8 single with no return for the HP big blocks, front springs, radiator and expansion tank. just to name a few.
If it has the big block rear end, then do a search on the other things listed and go from there.

Thanks.
This was also helpful from another thread I found... provided it is all correct.
Tach used in 1969:
Redline
5300 350/300
5600 427/390, 427/400
6000 350/350
6500 350/370(LT1), 427/435, 427/430 (L88 & ZL1)
1. copper radiator
2. BB hood, and 427 letters
3. Rear sway bar, yes a certain thinkness
4. Caps on your Ujoints at the yokes
5. Larger front sway bar, yes a certain thickness
6. heavier front spring with a certain label attached
7. Wider Radiator Support
8. Console engine tag that says 427
9. Tachometer redline
10. emmissions sticker behind your master cylinder
11. fuel line differences
12. transistor ignition ( some BB's did not have it though)
13. testamony from previous owners.
14. Fan Shroud.
15. Documentation, tank sticker, invoice, window sticker.. etc...
all of the above can be faked and added to make the car look like it was originally a BB car.
your NCRS judging guide will elaborate.

Original GM documentation with the car. Since everything about the big block was optional equipment, any and all of it could have been added by a previous owner any time in the past.
What engine is in the car now? Does the existing engine have your VIN derivitive stamp?
