The rear end is cheaper, the entire driveline for that matter will cost me less than top of the line parts, that will work, look right and pass tech in "stock"

I really do want it to be a stocker though

If you don't mind back-halving the car, it looks to me like the Boss 351 engine factors are a lot better for SS than Stock. Actually I think if I were trying this in stock I would be hammering NHRA to reduce that 355HP stock rating. There is absolutely no justification for a 50HP hit to the Boss engine as compared to the 285/305 variant in stock. No one has run the Boss engine in stock from what I can tell, while the 285 has been run quite a bit and has had AHFS hits and still only factors to 305. A point of compression and a little bigger cam surely doesn't justify a 50HP difference in otherwise identical engines.

In an earlier post you complained about having to put a lousy stock intake on your supernatural heads. SS would take care of that issue. The big ports in the heads has always argued for high RPMs, and a nice roller cam would help with that too, all with a more favorable 330HP rating (still too high IMHO, but a hell of a lot better than 355HP in stock).

The Boss engine is AHFS factored to 340 in a SS/GT too, a sure sign that there is something more there for it in regular SS at 330.

I'll bet Jim Evanuik could give you a lot of guidance on a SS variant.
