I wanna drag race----help

Today I finally got the 289 off the engine stand and the 340 out of the crate and mounted on the stand. Will partially disassemble the 340 to spot check clearances and make sure they match whats on the build sheet, also see how clean it is internally since it's been sitting for a few years. I bought some ARP head bolts and will install them and reassemble. I want to change the engine color to black since I will be accenting all aluminum parts (air cleaner/valve covers/billet pulleys) in orange anodizing. Any ideas about precleaning an already painted engine for repainting, it's alot easier when the parts come back from the machine shop hot tanked but this is different. I would also like to ask the racing guys out there about engine break in for racing. I know you are supposed to put some miles in with varied loads with no high RPM for break in but what do the race guys do when they don't street drive the car, do you have to mount it on a dyno to break it in? I've included a couple of pics the Duster which is now paintless, to make my goal of racing on the weekend of Oct 3 even more impossible I've decided to repaint it!!!! Ya I know.... my wife says I'm nuts too but I love a challenge and I'm no stranger to failure. Kev
