Hello all, I'm brand new to this forum and I had some question about a 1971 RS VIN and block id/vin numbers matching and exactly what it is. My stepfather passed away in April and among many auto parts and a few classic autos is this camaro, which from my research on this site appears to be an original RS package. I'm trying to figure out if the motor is original, the VIN # is 124871L513017, which tells me it's a V-8 built at the Van Nuys plant. The block ID # is V0310CGC, which from this site appears to be either a El Camino or Full Size, the partial VIN on the block is 11L513017. What I can't determine is whether this is actually the original motor and whether it's a 307 or 350. It has a 2 barrel carb. Any and all help is appreciated. Thanks!
