MAKE SURE...you prime the engine prior to start, you need to get oil pressure up and into that motor before you start it for the first time. You can purchase a prime tool from damn near any performance shop for 15 bucks or use a 1/4 socket TAPED to a long extension and a drill. You need to pull the dizzy, secure the socket or prime tool on the oil pump shaft in the dizzy hole and run the drill in REVERSE until you've built up oil pressure (you will feel the resistance build in the drill) and continue to run it for at least 1-2 minutes. You need 5 quarts of oil and once started keep a close eye on the oil pressure and temp gauges until up to temp...then your driving it. Once you've put 10 or so miles on it, bring it home, change the oil check for leaks, problems, then continue to drive it for the first while with your eyes fixed on the prssure and temp gauges varying RPM as much as possible and avoiding highways for the first 100 or so miles. I like to romp on it in second and third up to 5000 every so often..some like to do it right from the get go, your choice..your money. Good luck.
