My '64 came out of the factory with 3.90 Safe-T-Track, metallic manual brakes, manual steering, 750X14 Uniroyals, wide ratio 4 speed and Carter AFB. Showroom stock with Hoosier recap slicks, it ran

In 1965, I installed a '62 Big Pontiac Tripower with mechanical linkage (Ansen ball bearing crap linkage), Doug's 3-tube headers, milled heads .035", disconnected the vacuum advance, put weaker mechanical advance springs on the distributor along with a bushing to limit total advance to 34 degrees, and put Isky Polylocks on the rockers so the lifters could be adjusted to the end of their travel. I put an Air Lift bag in the right rear spring to equalize starting line traction. The best I ever ran with the 389 in this configuration was 13.29 @ 109.75 mph. I drove the car to work every day, as it was the only car I had then, similar to OMT at that time.
