The L48 used the basic 3896929 cam with 195*/202* Duration @ .050"; .395/.410 lift on 112* lobe seperation angle. Cylinder heads were 76cc chambers which along with the dished pistons gave it a rough 8.0:1 CR. The rotating assembly was cast. Being a 350 the rods were a standard 5.7". Bore 4".

I don't believe that link is entirely correct. The L-48 and L-82 used the same head casting for many years, number 462624, with the same 76 cc chamber but just larger valves in the L-82.
