"The 360 horse 409 came along in March, followed in extremely limited numbers by a ferocious dual quad 409 horse 409 in June- - these later cars were fitted with a special use chassis and a unique air intake system that was the precursor of the fabulous racing Z11s of 1962-1963."
'580X (RPO) is the "409 Turbo Fire V8" and 587B is the "Conversion Dual 4BC". 'This was a limited Production Option (LPO) for very late in the 1961 model year, or June, which included an "1109W Spec Use Chassis" and an "1110Z Performance Package". This was the forerunner to the fabulous Z11 racing Impalas of 1962-1963.'
This information is from a magazine called: CHEVY POWER, Milestones Series by Trader Publishing Company which has a Clearwater Florida address.
Wonder where they came up with this information. ? ?
