OK, I'll do some diggin and come up with several combos that will put me in K/SA. The weight break for it is 13.00 lbs/hp, and the index is 12.65.

Well, if I use the '72 455 we've discussed, I'll need one of the "Tons a Fun" Lemans wagons. Hey, I can live with that.

Next, I could run a '73 250hp 455. I could run farther under with a Bird, since the hp factor for 'em is 306. But, to make K with that engine I can use a Luxury Lemans, a GTO, or a GP. Hey, you can race just about anything with wheels on it. But I don't like the looks of the rear of the '73 Lemans and GTO. I'd much prefer the look of the GP.

The '74 250hp 455 is almost identical to the '73--same heads. So to make K with it I'd need a Grand Am or a GP. Once again, I'd prefer a GP.

I'd really prefer to run a 455 combo, because of it's low end torque, and lower operating rpm. But I'll go ahead and check out some options with smaller engines. I'll start with the 400. Most of the earlier years have an NHRA factor that is equal to or higher than the 455's. But some of the later model, low comp 400's have a decent factor.
The best one I see is the '77, with a 260hp factor, in anything except a Bird. All the big cars were downsized that year. So I could make K with Cats, Bonnies, 2-door Lemans models, and a Can Am. Of these, I'd much rather run the Can Am. But that's now sort of a high dollar collector car. So, one of the others would have to do. I'm thinkin that if you can find a good clean one, that one of the Cats or Bonnies would be the cheapest. And would probably look a bit better too.(at least to me)

I just checked out the 350 engines. To me, they are factored too close to the 400 factors, and give up 50 cubes. So I would not try to run a 350.
OK, to summarize this post, for K/SA, as of right now, I'd prefer to run a 455 in either '72, '73 'or '74. The '72 would be in a Lemans wagon. Both the '73 and '74 would be in a Grand Prix. But, I haven't seen any GP's racing. There may be a good reason--don't know yet.
