.016 as a reference
0.035 inch was a previous answer. I would seriously verify that. I show 0.035" as the SPARK GAP of the spark plugs, not the point gap inside the distributor. The point gap I found was more like 0.017" measured with the points open on the high lobe of the distributor shaft.
I remove the distributor and rotate until the points are at the widest opening. Then using a .017mm fueler Gage I set the point gap. Reinstall the distributor, set timing and roll!
A 79 shouldn't have points to gap. It should be an HEI distributor.
points gap 17
It should have an electronic distributor. So no points to adjust. 0.18
If you are using the original points distributor, the gap would be .035".
Spark Plug (ACDelco R45TS) [Gap @ .035” for points distributor, .045” for HEI distributor]
If it has points in the distributor then it is 0.035 If it has an HEI distributor then it is 0.045
I don't think you will find points on a '94
The air gap between the the tooth on the distributor shaft and the pick up coil should be .006. Be sure to use a brass feeler gage when setting the gap. Align blades good,And adjust to .008th.
the gap on the distributor points is .016, the timing is advanced 4 degrees and the spark plug gap is .030
