Yes about 15 initial if you have 20 more in the dist... 35-36 total is good starting point assuming enough octane (91) and good mix. Read the plugs for mix and timing. Look for "blue line" on ground electrode from heat. This line should be about at the bend in the strap when the full timing is right. More advance moves the line further down... When it gets to the base bad things start to happen...
