5speed GT

... the topic is no question but a statment. When I rebuilt the motor(600 miles ago) I set the timing to 10* for "break in". I later bumped it up. When I set it I had a little trouble seeing the markers, so I set it to 12* or 14*(I couldnt tell which) and running 89 octane I had no pinging so I let it eat for the last 200 miles. Tonight I figured I would check to see if it was at 12* because I wanted to bump it up to 14* if it wasnt. So I marked the pulley at 14* and it was at 16*... so I set it back to 14* and it made a large seat of the pants difffence in my opinion. I would say 14* is the sweet spot

timing is the point in which the piston travels up and the exhaust valve opens as the spark ignites the fuel and makes combustion. advancing too much, you will be sparking before the process is completed, meens less power, bad on motor.


Advancing the timing higher, gives you a higher degree of total timing , most of which may be absolutely useless.You may see a power increase for a certain time frame and thats at, not throughout the band, CLIMBING POWER. your gonna have to experiment with diffERENT settings.


if you have a stock car, timing should at least be 10 , no more than 19 , YOUR ENGINE HAS NO BREAK IN PROCEDURE, DONT BELIEVE IN THAT
