I set the timing to 18 for idle yesterday with
the 670 on the car. Set idle to 850 and adjusted
mixture screws. Took her out and mashed on it
and the car is running very good. No knock or
ping from off the line or from higher speed
even from 4th gear at say 2000 rpm.

I will look into the disy curve also. Happy to
have had weather break enough to drive her!

I think the 670 will be staying on the 340. I
cant really tell much of a higher rpm difference from the 3310 and it seems to give me zero
bog or lag issues and throttle response if much
better. Thanks all!
