68first gen Frond spoiler strenght

[Roadrage David]

Guys i have had my car up to 170mph on the high way, with a 68 first gen frond spoiler, and the 3 conecting rods /braces ore however you whant to call them that came along with the spoiler
.
Im going to change the rear gear ratio into a 3.08 from a 3.42. and going to ad upgrade to a new sollid roller cam that will give me around 70 more hp and 400 more rpm range.
The 170 mph run was done at 5200 rpm. engine now can run 6200 rpm . my question is if i reanforce the spoiler with 2 aditional rods ore braces will it hold up to 200 mph??? as that is my goal to reatch............. i have read that it was safe upto 140mph in its curend state, but have gone past that speed more then once..... david
