Yes. It really does perform extremely well at low RPM. I could drive all day at 45 MPH and just under 800 RPMs at that speed (with my really high gearing). You'd be hard pressed to find a better low RPM camshaft for the LT1.

Except for tuning, and removing unnecessary accessories (power steering, A/C), my engine is completely stock.

To clarify: I can achieve 46 MPG with my lightweight 2.14 ratio rear end. I've only done about 42 MPG so far with the 4.10 14-bolt axle.

And I think the difference there has more to do with the additional weight and parasitic loss, than with the difference in gearing, per se. I can achieve 46 MPG with the 2.14 axle even if I never go above 3rd gear.

The point is that the biggest gains can be made with highly refined driving technique--especially P&G with EOC.
