Looking for stock slant performance #'s D150

I only payed $75 for the car, a couple of weeks prior. Hadn't done anything to it. The previous owner had many things "out of wack". Like I mentioned in my post the biggest thing was to get that Holley 1920 to open all the way. Oh, yeah also pumped the front tires up to about 40 lbs. I did stop short of taking a hack saw to the cut the exhaust pipe before the muffler.
I have found on several 2nd hand cars where the throttle only goes part way open under WOT.
