Re: It's Almost Here!!
Duane,
Norwood cars had either L78 or L34 stamped on the cowl tag in 1970. I don't know how you can tell a Van Nuys '70 big block without documentation.
Roger,
LS3 is the engine code for the big block in 1971 (300 hp gross,260 net) and 1972 (240 hp net).

(I have not become an instant expert on these cars, please feel free to jump in and correct me)
