Rod Green has a D/S T/A Challenger in the works. The T/A can run C/S-A, D/S-A or E/S-A as the car falls at 9.59 (at) or 9.83 (stick).
The AAR 'Cuda falls at 10.09 / 10.34 making it a D/E/F car.
Back to the original question, nobody has raced a '69 or '70 Boss 302 in a long time. None that I'm aware of at least. But I've always thought "if I had money to burn", I would build a '70 Boss 302. With the camshaft and valvetrain technology available today, along with the clutches & transmissions we have (don't forget aftermarket rods too), I believe you could launch the car at 8K whereas once before that may not have been possible on a 9" slick. The '70 would still be the way to go due to the smaller ports.
Dynacor just released their aftermarket '69-'70 Mustang FB so now you could build the car the right way without dealing with a 39-40 year old body.
And if it just doesn't work at all, just pull out the 302 and drop in a 428.
But I really think the 302 will work. If nothing it would be a lot of fun!
The '69-'70 Boss 302 are NHRA rated @ 305HP and both years fall into F/S so you can run E/F/G (stick only). Figure 3220#'s in E/S.
Cam lift (.502" I/E) and compression look the same both years. I'm not sure if the head specs are the same with superseded parts.

The 69 & 70 Boss 302 head are same ports only difference is 69 had 2.24 intake valve and 70 had 2.19 intake. Also stay away from the Doze-A block as it was not a square bore casting and will not stand +.060 over bore.
