Help me hook this thing up... I have the Chevy guys gunnin' for me...

Note, of course, the 'budget' was abandoned with the engine build ;)

This is it then?
* Caltracs for twist
* Spring relocation for more tire
* Good shocks for control
* Sticky tires for race day

My other questions are;
* Convertor? Mainly street use. Cam spec says 2800 rpm (for a 360) but I'm thinking a 2600 for the 408. We have a good converter guy in town (Dodge guy too). He can work his magic.
* Trans? 727 leaning toward the typical set up but I keep thinking about a manual valve body. Anyone tried both?
* Tire size? I think the best I can get with this stance is a 245 x 26-27". Is that correct?
* Gearing? Cam spec says 3.73 but Darts are fairly light and, if I have this right, the 408's torque does not really benefit from the lower gearing. Either a 3.23 or 3.55?

What are the chances that intake and carb will fit under the hood... none? If this is the case I'll need a scoop and the whole sleeper thing is out the window. Fine with that.
Thanks for your input.
