i crossed with the speedo (correted) at over 120 mph and still 300-400 rpm left on the table looking good and that was my very frist pass with this moter. not to bad for the 1st throw at the cat. but the winneing sounds comeing fron the doo camp was pitiful no tration, to much power, not good condtions, etc,etc . cry me a river but the numbers dont lie. and the best one was i dont have studs well nether did lots of us me inclluded. contions were good and bad ice with lots of wet spots with smalll paches of slush. far from idel. but i was the same for every one. headed back out today.

got it running good still trying to get it dialed in a little better. i just jetted up about 7-8 points tonite as it was running realy lean. so i will give it another run tomorw . and no i did not do the porting.
it pulls hard very hard.
