The '69 T/A is now legal for Stock competition. A '69 T/A clone would make a cool Stocker, IMO.

But, with the RA3 engine being rated at 356 hp, I don't think it would be too competitive. Due to the cam rules, I don't think it has any more potential than the 330hp engine, which is rated at 345. Anybody know how much power difference the RA system would make, on a '69 Bird Stocker ? Are the Ram Air cars even required to run the RA system ? Anyhow, like a lot of other combos, it could be built to run just barely under the index. Sometimes, after a combo is run for a while, NHRA can be talked into reducing the hp factor.
