what is point setting for chev 350 v8 engine Use dwell meter to set the gap to 30 degrees dwell.
Chev 350's haven't used points for a long time. If you have an older one, just put the new points in place & reassemble the distributor, then, with the engine running, open the little window and use an Allen wrench to adjust the dwell. Of course, that means that you will need a dwell/tach. Newer Chev 350's don't have points. Correct dwell would be 30 degrees.
attach a dwell meter and set the points for 30 degrees.
Dwell is the length of time the points are closed and the coil saturates.... adjusting the dwell changes the timing so do dwell first. Be sure to apply lube to point block. Connect a suitable dwell meter to the car. Putting an Allen wrench thru the side window on the distributor and into the recepticle on the points and turning it, raises it or lowers it. When you achieve the correct reading, close the window. Then you must adjust your timing. 350's like 8 to 10 btc.
