I knew the correct answers.  I was just keeping my trap shut and letting someone else have a chance. . . . 
 
OK  I guess I need to put this to rest
 
Snotty is correct.  Without looking at the carb or the pad, you can't tell physically if it's a 383 or a 400.  Neither are RB's  B's and RB's share allot of components
 
The 400 used a Holly or a TQ and the 383 was packahed with a carter 2 or 4 BBL.  A TQ was never used on a 383.  It wasn'r made yet.
 
Good info Stan

The guy that I got my car from tells me at every freakin cruise-in and show I see him at that my engine (383) came out of a 68 Road Runner. Is there a way to tell if this is fact or crap??? I was told by others years ago that RR's had a "special" 383 different from everyday joe blow passenger cars. Is it true or what??? What is the difference if really any?

I thought your question was:
 
"Without crawling under a car to see the casting numbers, or without checking any sequence numbers etc, and just looking at a car with it's hood up, how do you know a B from an RB?"  
 
I have one:  How can you tell a A-833 from a BW T-10 by looking at the shifter?

The only way to tell if your 383 is from a Roadrunner, Ardoggy, is if the VIN on the oil pan rail starts out RM 21; RM23....something like that. Otherwise all of those 383's look the same. The cam and intake, exhaust manifolds were different for RR's.

I agree with Bob.  Externally, the only difference was the use of the 440 exhaust manifolds on the 383 block.  But that is such a common sight today that I wouldn't use that as a basis for determining it.  I thing he's just jawboning to look smart.
