MPP is about right. Hahaha
In town, I expect it to be just like any other bigblock. Thats allot of weight to get moving. so 7 to 9 mpg city. But on the highway, it should be in the 14mpg range. With the gear reduction of the axles, I can actually move this thing around the yard by twisting the axle pinion by hand. No joke.
6.72:1 gears. Even with 40" tall tires, thats like running a 5.0:1 gear on stock street tires. With the overdrive of the 4L80E, im looking at 2600 rpm at 75 mph. Liveable.
This is all counting on me being able to keep my foot out of the throttle. But lets face it. With 800 hp... thats just not going to happen. Thats why the fuel tank is 43 gallons. Heheh
