Best thing to use for locating sounds is a long screwdriver. Put the end of the handle against your ear and the blade of the screwdriver on the part. It localizes very well. A stethoscope has too broad a sound pickup field.

Did you check the fuel pump for the noise? It gets punched by the cam every time around, right?

You really need antifreeze in there. Most low-compression sbcs run cold.

You can probably run base timing of 16* BTDC with no problems as long as you have the right vac advance can on there.

Idle of 650 is still a bit high for a stick. 700 for a slushbox in P/N, 550 or so in D/R. More like 550-600 for a stick in N.
