Abraham,
My references do not include a "73" 400. They show "74 thru 76". Jon

Abraham, Checking further I find that they did indeed have a 400 in 73. What would you like to know?

Well,
I'd like to know the horse power and torque. Also the valve size and compression ratio. It's a 4 barrel motor. My elky is a 74, but i beleive that it's an early '74. some of the parts,etc. are '73. Thanks

The 1974 400cu 4bbl small block found in the Chevrolet A-body line up would have either been suffix code CSU or CTC. The horsepower would have been 180hp (net).

The cylinder head most likely used on this engine from the factory would have been casting number 333882 and would that would have featured a 1.94" intake valve and a 1.5" exhaust valve th a combustion chamber volume of 75.47cc.
