Isn't a parade probably the worst way to break in a new engine? I'm no master engine builder but if I recall part of the break in procedure is varying the rpm's, loading and unloading the engine, etc to help seat the rings, putt putting along in a parade at extreme temperatures (your engine going to run even hotter with a fresh, tight rebuild) is probably not a great way to do it...I hope you'll be doing the following (or your preferred variation) on Friday...
1. Always bring engine to FULL operating temperature before high revs.
2. Drive the car easy for the first 10 miles or so, varying the rpm's from 2,000 - 5,000. 3. Then, start bringing the engine up to maximum rpm's and letting the engine bring the revs back down by coasting in gear (vaccum pulls). 4. Repeat several times in order to create maximum heat in the cylinders. 5. Drive around at lower RPM's for several more miles, remembering to vary the speed of the engine every couple of miles. 6. Repeat number 3, 4 and 5. 7. Park car and let the engine cool down overnight. 8. Repeat all the above 2 more times. (This is just a break-in procedure I found on the net from a 35 year engine builder, they all seem to have there own variation but the concept is similar, varying speeds, varying loads)
