Mike there a plenty more guys on here with more experience on what you could think about to get the best time out of your manual SRT but here's some thoughts.
Final drive ratio in my auto was 3.06 yours I think is 391. But the red line on the revs is the same I believe. So you could have more control over revs at launch and more bite because of your rear set up.
The smaller the diameter of wheel and tyre combined the more revolutions per distance travelled so if I still had the SRT I might have looked at 18" wheels and different tyres just for Santa Pod. 20" stock tyre is .5 taller than stock18 inch. So 20" = 703 revs/mile. 18" = 716. With the Brembo calipers 18" wheel fits fine, some guys in the states use 17" shaved wheels. It's all extra cost for small return but have a look at challengertalk forum for more info. Plus you could consider a Diablo plug in if you're happy to mess with preset engine settings.
