Can I roll back time?

[Mike Bradbury]

When I bought my truck it had 144,000 original miles on it. In '92 the motor was changed to a 350 crate motor and it had 14,000 at the time of purchase. Since then I have changed the rear end to new, drive shafts, U-joints, and carrier bearing to new, transmission to new, motor has been completely rebuilt (block is the only thing is not new in the engine and it was bored out), four wheel disk brake conversion (all new components), new springs on all four wheels. There is not one thing on the entire drive train the is not new. My question is can I roll back the odometer to zero or is that a frowned upon? It is not a big deal to me one way or another, really more of a convenience thing. As I start putting miles on the new engine, I would like to look at the o.d. reading and not have to subtract 144,000 each time I want to know how many miles I have on my engine. I realize there is a certain vintage to having an odometer reading that reflects how long the truck has been around but in my mind the odometer reading is for drive train not the sheet metal
