Our father still has a 1966 Shelby GT350H. Can anybody remember what the "H" signifies?

Hertz.

#1 Question Are you in his will?

[Charles Martel]

Hertz dropped the "rent-a-racer" advertising angle after just one year, because people were doing exactly that. Rent the Shelby, then go compete at Willow Springs, Lime Rock, Laguna Seca, etc. Sometimes those cars even "donated" their engines to somebody's Shelby Cobra (without Hertz's prior approval). If it has gold stripes, it's quite likely an original Hertz car (most were gold stripes over black, Hertz corporate colors).

Any idea whether your dad's car is on the SAAC registry? I think you can compare the Shelby VIN tag under the hood to the SAAC's listing at their website.

My Dad’s friend had a 69 Shelby 350H that he was selling for $2,000 back in 1974.

I told him I would buy it and he sold it out from under me.

Never talked to him again, turned out to be a real A Hole.

It was over 40 Years ago and it still pisses me off.
My Wife tells me to let it go, but it’s a Guy thing. LOL
