how do i set a 327 9 degrees back
To set the dwell on a 1968 Chevrolet 327 engine, you'll need a dwell meter. First, connect the dwell meter leads to the ignition coil's negative terminal and ground. Start the engine and let it warm up, then check the dwell reading. Adjust the points gap using a feeler gauge to achieve the desired dwell angle, typically around 30-32 degrees for the 327, by loosening the points screw and repositioning the points as needed.
Depends on weather your referring to a modern vehicle with a fuel injection 327, or a classic car. Depends on if points or electronic ignition . An example being a 68 Chevy 327 with points type distributor I set the gap at .035 now same engine with electronic ignition HEI distributor Icap a bit larger a max of .045
0.19 for brand-new points 0.16 gap for used points. The above answer may be adequate to get the engine running, but points are set correctly when you have a reading of 30 degrees on a dwell meter.
use a dwell meter to set points to 30 degrees
That requires an OBDII engine scanner to set the timing to factory specs.
Set the motor to TDC, pull the #1 spark plug, put a small wooden dowl rod in the cylinder, rotate the engine and measure the stroke. 3.25" = 327, 3.48" = 350
If you mean ignition points, no.
The timing is totally controlled by the engine control module.
30 degrees dwell
My advice would be to set the points at .020" with a feeler gage to get the engine running, and then use a dwell meter to set the dwell after the engine is running.
O-Boy !! The engine has electronic ignition. *** NO POINTS ***
It is set and adjusted by the engine control module.
