Looking for stock slant performance #'s D150
22.8 down to 18.9 is some serious tweaking in a day of tuning!!
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 had another car that really supprised me. 1974 Dart 4dr 318, 904, 2.93 7 1/4 rear. Bone stock except for a aftermarket 4 bbl intake, and a holly 4 bbl from a 440 engine.
The OEM 2 bbl was bad, and I had the 4 bbl parts, so put them on. Found I had a large vacuum leak at the base of the carb. So put on a NOS plate as a spacer the seal the carb. Then decided to do the complete NOS system. Car had over 100,000 miles on the odo. Took the car to the track, opened up the "noodle" single exhaust before the muffler, put on a set of 22x8x13 slicks, and made a motor only pass, letting the car shift itself. Don't remember exactly what the ET was, but around a high 15 or low 16 sec pass. Then turned on the bottle, and used a line lock button on the shift handle to acuate it. 1st pass just in high gear (was not really impressed). Next pass 2nd and 3rd (felt better). 3rd pass, said what the hell, on hit it right off the line (now i'm impressed) Went a 13.8 at over 100 mph. My wife drove that car for several years. Then I removed the NOS and gave the car to my niece.
