NASCAR uses a carburettor because as soon as you introduce fuel injection, you open the door to traction control, and you'll never close that door again (as evidenced by F1 in the mid 90's).
In my opinion, the 4 major engine types in NASCAR at the moment are more different from each other than the current engines in F1. there is atleast variance in cylinder head styles, displacement, and to a lesser extent, valvetrains.
I can't recall a single piece of F1 technology making it into a streetcar. I'm sure if I worked at it I could come up with one. I can recall at the SAE motorsports convention in 2004 a few where brought up, but they where very few and very far between. Infact it was brought up that in F1 they can do many many things and little to none of it will trickle down to roadcars. Whereas MotoGP/AMA Supercross and the national Snowcross circuits have to actively be carefull about what they add to race machines, because if it's not available on a consumer product within 12-18 months, there will be a consumer backlash.
I do agree tho, for the most part, stock car racing is about concentration and driver ability, not the vehicle. I think this is largely due to the lack of electronic nannies (back to the carburettors thing again.)
for what it's worth I don't like either of those forms of racing, I do try to keep appraised on what's going on in both tho.
