What are you doing to your racecar now?

Changing from a tired 340 in 71 Dart to a fresh 360 with ported Eddy heads, along with new converter. Should knock about a second off the car's previous best time. Got it all bolted in..just working on the small stuff, first race is march 15, dont think the Dart is going to make it since it is also part for primer and paint...too many things to do.
