I see people use the term "Daily Driver". WHat do you mean? When do you consider the car to be "Race"? I am rebuilding, and going for 400rwhp, but I drive the car a couple times a week and twice a month at the track, 1/4 and 1/8. Of course I am thinking about 40 over pistons, I would like to go 25 or 30 over if I can find them in the odd size. The machinist said I can probabley get off sizes, but I have to wait for the pistons.
