1967 Assembly Manual (also 1966 AIM):
In the 1967 AIM, UPC C60-C2, RH side, under optional parts that install the same as regular production, is listed 6440083 ASM - PUMP. (the 1966 AIM also shows the same p/n in C60-C2)
UPC L79-A2 (1966 & 1967) shows that a different "Fuel & Vacuum Pump" was used with RPO L79, installed the same as regular production, but does not specify a GM part number (says "See parts list or bill of materials for part numbers.")
Noland Adams' book says:
"For 1964, L76 and L84 engines had a higher output fuel pump, part number 6440083. Base pumps were rated at 5.25 to 6.5 psi at 1800 rpm, the 6440083 pump was rated at 6 to 7.5 psi at 1800 rpm." (p. 231)
"The 1966 C60 fuel pump was a high output unit, part number 6440083. This unit was also used with the L79 engine." (p. 339)
Judging Guides, P&As:
The 1966 JG confirms the higher output 6440083 Fuel Pump for L79 (no mention of usage with C60). The 1967 JG does not mention a different fuel pump for C60 or L79. The 1966 P&A references 6440083 being used from 64-66 "w/F.I., Sp. H/Per., C.A.C.". The 1967 and newer P&As say the same thing (model year 1964-66 usage), but the omission of 1967 model year usage is not conclusive, since many original production parts used in 1967 are omitted in the 1967+ P&As, showing 1966 as the last year of usage.
A search of the TDB archives for p/n 6440083 turned up nothing in relation to 1967 small blocks, but the 1967 AIM says this fuel pump was used in 1967 with the same RPOs as 1966.
Was the higher output 6440083 Fuel Pump original equipment on a 1967 SB, with C60 or L79 (or with both C60 and L79)?
