Meep meep; YES SIR! Though living at sea level has an edge others up in the air don't have, I think the basics of what I did and what you can do will help no matter where you are in a similar way. Things I could have done to help mileage, but, never got to doing. A better dual plane intake. Theres nothing wrong with the factory 4bbl intake, but, I think even a performer would have helped. Weight not the issue, though I guess a few pounds here and there would help. I'm a big fan of a T-Q. The tiny primarys for better atomizeing and a higher velocity would have been the target and reason for the carb, though any carb well tuned is worth it's weight. The Carter 625 emissions carb I used was a very good carb. Dead reliable. Headers! Over the factory iron manifolds, Yep, you bet ha ha ha. I was also considering a cam change. A split duration unit, a real low RPM turner. I was entertaining (SP?) 2 cams in my head when I had this car. They were; Comp Cams ...................RPM range.....Adv. Duration..@ .050......lift............C-line Dual energy; .1200 - 5500 - 255/275 - .....203/219 - .422/.462 - 110 w/manifolds Extrm. energy; 800 - 4800 - 250/260 - 206/212 .432/.444 - 110 w/ headers (For effect, when you read below, play the music from "Star wars , the tracks of when Darth Vader is on screen, the meanceing "Empire" music) At the time, New York State just installed into the auto shops, by law a dyno emissions tool where you had to run the car on the rollers at Hwy. speed for a short time and pass emissions while at speed. At the time, it was the only way you could get a passing sticker for a car not old enuff to skip the test. Living within the metro area and not haveing a car older than 20 years old at the time, I was faced with being screwed and not haveing a car should I fail. The car also had twin cats before the "H" pipe and all emission parts hooked up including the floor jets in the intake manifold. Everything had to be in order. As a final insult and a big dose of "Big Brother", the state installed video cams at every test station for "Big Brother" to radomly check and make sure the test was being done correctly. Should the shop be found to skew the test in someway other than the exacting procidure writin up by the state, the shop would loose there license and abilty to work as a legal shop, period! (The Darth Vader music also works very nicely when mentioning, "Anything "New York, the Empire State") Nice huh?
