[Fot] GT6 Connecting rods

Fri Dec 11 19:06:17 MST 2015

Dennis sent my Ford 1500 crank to a guy in Colorado for nitriding.  He said it would be about $800, including final straightening and grinding to spec (Monday I’ll pick it up and find out what the final cost is).

Russ's comments are dead on - building the car is one expense, racing it is a recurring one and his estimate of $1000 per event is good. So build in margin of safety in the motor (and other components) where you can.
