In 1963 and 64 GM built a 429 it was in the caddy
1964 is the first year for “climate control� heating and air conditioning systems in Cadillac.
1,870 El Dorados built in 1964, all were convertibles.

SPECIFICATIONS

ENGINE: Eight-cylinder, 340 H.P., overhead, 90 degrees V-type; bore 4.13"; stroke 4.0"; displacement 429 cu. In. Max. torque 480 ft.-lbs. Engine mounted in rubber at three points. Compression ratio 10.5 to 1.

PISTONS: Aluminum alloy, slipper type to reduce friction surfaces and permit nesting between crankshaft counterweights. Two compression rings, one oil ring with expander; top compression ring chrome-plated to minimize wear on cylinder walls. Recessed contour in piston head increases turbulence for fast, complete burning of fuel-air mixture.

CARBURETOR: Four-barrel downdraft with equalized manifolding; mechanical fuel pump; dry type air filter; automatic choke.

LUBRICATION: Full pressure. Full-flow oil filter standard
