The VIN listed shows 1511 which is a BelAir 6 cyl. 2 Door Sedan. 1611 would be a BelAir V-8 2 Door Sedan. The VIN information takes precedence over the Cowl Data tag information for the SERIES (second and third digit on driver's door post stainless tag).
There is a Red 1962 2Dr Sedan BelAir '409' $$$ car and a Red 1962 2Dr Sedan Biscayne '409' $$$ car on that auction site presently...both were originally 6-Cyl from the factory..Just saying be aware...guess i need to pull that Chevy 350 engine out of my TRUE V-8 "1211" code 1962 Biscayne and transplant that extra 409 sitting here....presto extra $20K in value!
"This is a non numbers matching car" could mean "not the exact original 409 engine" or guess it could mean "was a 6-cyl now a 409".....
Paul, looks like you might be seeing the 2 extra tubes at the fire wall are the heater control valve...maybe this heater only came on Impalas, but does look like my 61 impala heater at the firewall..... I thought the valve covers were hilarious....
Correct Dean there should be 4 outlets for the heater, I guess I was pointing out
that the heater was bypassed by running a hose from the water pump to the intake and leaving
the 4 heater outlets wide open ( which is strange for a fully restored car)
