Amazing fuel economy. My LT-1 740 wagon has the Tremec T56 with a 0.5 6th gear overdrive ratio. With the stock (turbo, M46) 3.31 axle, the engine runs at 1620 RPM at 70MPH. At that speed on the Interstate it gets 26MPG(US). I have proven this as an average over 1000's of miles.
Low restriction intake and exhaust, heads resurfaced .010" with 3-angle valve job, and it's 100% California smog legal...got the BAR sticker on the B-pillar. It is a real hot to drive, a smile every time! And there's no better "sleeper" or Q-ship. It looks like Gramps in his old square Volvo, then, two black stripes and...gone.
Your car must be running extremely well to get that fuel mileage with the automatic and its 0.7 OD ratio...well done!
