.. Most important part for a 401... LOL!:

Offenhauser 360 Degree Dual Quad High-Rise Intake Manifolds 5692 -

.. All other 401 parts readily available...

.. SBC 400 cheaper to build than a 383... don't even need to change the crank... 400 is a 383 with .095" overbore already done.. 406 is 383 with .125" overbore...

.. Buick 401/425 and SBC 400 include big torque at no extra cost...

.. SBC 400 steam holes no big deal, lay gasket on new heads (if used) and drill 1/8" hole where gasket indicates... only need to drill the 3 lower holes in each head, any steam or air bubbles where the upper holes would be just floats up and out the water jacket hole above it... as long as you don't drive the vehicle upside down... cam buttons for roller cams are the same (simple) problem for any size Gen. 1 SBC that didn't come stock with roller cam/provisions (pre-1986)...
