66 fuel pump and some bolt questions
I have a 66 assembled May 17, 1966 with a base engine. The judging manuel says early pumps were 5594657 with 6440433 introduced later in the year. To complicate things it appears a 6440083 (350 hp) pump clone is on the engine now. The pump on the engine now has no discernible markings. Which is the correct pump? I have bolts on my valve covers and intake manifolds with the letters nat on them. Are these incorrect? Thanks for any help in advance. Bob.

Robert,
I can answer the bolt question I would concider your 66 a late 66 and they started using the 67 up bolts which have a 7/16" head. Early 66's had bolts with a 3/8" head. NAT is a period correct headmarking. NAT is also correct for the intake.
