427 Fairlanes for 1967
(That’s not the Mystery but it so easily could be)
Basic Info, NHRA Shipping Weights, 427-4v (modern tables, “pretty close” to the old ones)
3280 Fairlane Club 2ds, the lightest one
3320 Fairlane 500 2ds
3400 Fairlane 500 2ht the most common
3688 Fairlane 500 2cv Convertible eg Dick Simon
3772 Fairlane 4d6p Wagon eg Richard Charbonneau

From there:
20 lb: add for 8v
40 lb, subtract for race package, glass scoop hood etc

Lots of urban legend about what was OFFERED, what was BUILT, what was LEGAL, and how the engines were FACTORED. The latter two even vary by race year.

I use FACTORED HP, FHP, for the 1966-71 race years 427 Medium Riser of:
410 427-4v flat hood
420 427-4v scoop hood (near as I can tell this combo was banned circa 1970, then allowed again)
460 427-8v flat hood
470 427-8v scoop hood
There is a little slop in these FHP, because things don’t line up exactly between the old and new weight tables.

This leads to an ongoing mystery, the Dick Simon car[s].
Simon’s more well known 67 Convertible ran in A/SA=8.00 at 68 US Nationals
This fits class with a 427-8v under the hood, W/P=8.00
And then ran in C/SA=9.00 “later”
This fits class from 1973 on with a 427-4v, W/P=9.00
But what is the Dick Simon car running at 69 US Nationals, F/SA=10.00?
No Ford engine fits that class unless it was a 1-of-none 428CJ in his 67 Fairlane
(That was a joke)
So here are some F/SA=10.00 combos that fit, but Dick Simon HAD to be running some other car, not his well known 289-2v then 427-8v then 427-4v powered Convertible.

Does anybody know what car/engine Dick Simon really ran in F/SA=10.00?
