<VV> IT'S ALIVE!!!!!

[James Davis]

The distribution number (# 1110330),with its associated advance 
curve, and static timing should match the heads (18 degrees 
BTDC).   Idle quality is almost total dependant on the valve overlap 
of the cam timing.  With a 216 degree cam (at 0.050 lift), it should 
idle at 650-700 rpm when the engine is broken-in (1,000 miles or 
so).  Before the engine is broken-in, the friction of the rings 
against the rough cylinders and the extra oil in the combustion 
chambers prevent a stable low idle.   With a new cam (non roller) and 
lifters all cam manufactures recommend that you run the engine for 30 
minutes at about 2,000 rpm to bed the cam and lifters in.
Your engine sounds ok except for the valve noise and that usually 
takes about 20-30 minutes to quiet down on a new rebuild.  Your 
download speed here was 9-10 kB/sec on a 75 kB/sec dsl line.
