Supercharged 410/408 stroker?
Take a look at the dakota boards. There are alot of guys running centrifugal supercharged 408s. Some of them are running mid 10s with 4200# trucks=P~
Here is one.

Another thing to note is that it takes more flow to feed a 408 than a 360 .... if you don't have the right supercharger the difference in displacement may not correlate with HP
