Carb change.....

No vacume readings.
We've veered off to the 'mostly track' lane. When the engine was built, and I ordered the carb, I did it with the idea that we'd be shifting around 63-6500 when all said and done. But since the thing pulled so hard and bounced off the 7000 limiter, we decided to add a stiffer gear and thought it prudent to go with the dominator to feed the extra rev's. The heads and the cam should be happy.

Thanks for your reply,

I was curious as to what your vacuum reading at wide open throttle was so as to determine whether or not your 950 hp was acting as a restriction, and also to compare it to the new dominator reading. :-)

I've heard that once .5 inch of mercury is seen at WOT, a larger carb won't make any difference. I'd like to find out if this is true or not. Since my Duster isn't done, I was hoping I could get some numbers from you to prove or disprove this theory, since your already swapping out to a larger carb.
