16* may be pushing it too far
go with 12*-14*
chalk the timing marks underneath, start the car, pull the SPOUT out (it's the shunt plug in the harness of the distributor)
then attach to plug wire #1 w/ your gun and shoot the timing marks.....
oh yeah, b4 you start go to sears and buy a 1/2" dist. wrench for $8.95 and make your life real EZ.
anyway..loosen the 1/2" hold down bolt, and turn the dist. while you shoot the marks...go to BTDC...ATDC only goes to 10* i think so you tell which way to go.
each little mark is 2*
lock it down when it's good, put the SPOUT back in in your done
make sure you use premium when you do it beyond 12* and listen for knock and read your plugs...you don't always hear spark-knock
