I inherited this truck from my father, James Harold Day, November, 1998, when he passed away at the age of 74. The truck had 24,000 miles on it. Needless to say, this truck is very special to me.

Original/Stock specs:

454 CID / 7.4 L engine, 7.9:1 compression ratio. Factory rated 230 hp/385 tq. (But not anymore! I have awakened the beast.)

3 Speed Turbo-Hydromatic 400 transmission.

110 mph speedometer.

275-60/15 BF Goodrich Radials, with Sport chrome wheels, black center caps with red bowtie emblem.
