I'm running a Weber 32/36 carb, plugged off the EGR, added a Spal 12" electric fan kit, and run Pertronix ignition. I'm using a Ford Ranger 2.3 Exhaust header which requires modifying the header pipe, but an easier fit than tube headers which always have leaked for me or had clearance problems. Because I'm running a T5, 5 Speed, I was able to get close to 34mpg on the Pinto Stampede cause we were driving so slow the whole way. I'm going to go for the larger, single stage Weber next with a snorkel and new cold air intake. The car is fun to drive and will easily top 100 mph with a basically stock engine. Of course it's lighter than a wagon...
My 2 cents,
Joe
