way too slow at drag strip! what should it run?
Sorry, a lot here doesn't make sense to me (I'm a little slow...lol). Your '60 foot times, and your 1/4 times and the mph are right on with each other. Another words, most 12.70 cars will run around 104 mph with a 1.8 60' time. It's not like you cut a 1.5 60' and ran a 12.70, or ran 114 mph at 12.70, but it sounds like your whole ET went hand in hand. And 4400 rpm's is what you crossed the traps???? Really?? With 3.91's and a 3500 stall at 104 mph??? This means you would be cruising 55 mph at about 1700 rpm's down the highway, with that converter and gears??? Is that tach way out of calibration causing you to over rev it by 1000 rpm's, thus causing the break up? And then, I've never had a car have a total advancement target of 28 degrees. I guess I've missed something there too. 37-44 degrees is where I've usually ended up. And also, 5 psi of fuel wouldn't cause it to pop and snap as soon as it hooked up, you wouldn't be out of gas that quickly. A lot here does not add up to me. BUT, I agree, the car should be well into the 11's, and 3.91 gears should get that done with ease. HMmmmmmm
