360 build in a 66 Cuda

OK I have the motor now and have started to gather parts!

So far I have :

-22,500 mile 1975 360
-1975 Jheads (974 Casting)
-Holley 670 Street Avenger
-Weiand Action Plus Highrise Dual plane intake
-Comp Cams XE 262 H Camshaft
-Comp Cams Lifter Set
-MSD 6a
-Mopar electronic distributor from the 360

Sticker on the valve cover designates this as a school bus Engine? Does this mean anything Special/Different from a regular 360?

I am not really building a race car, mostly a driver with the occasional friday night appearance at the "Secret Street" Drags in my city, or perhaps some braket type stuff (perhaps 5-6 trips to the strip in a summer).

For my own personal satisfaction, the first 200ft from the light, is probably where I find most important.

as for gearing, my rear is currently housing 3.21 (I think)gears in a 8.25 rear end. this rear end seems a little to high of RPM's with the current slant at highway speeds. Wille my rpm's drop much at 110 km/hr with the v-8?

I am planning on using my converter from the slant A-904, as I hear this would be an inprovement over a stock V-8 one is this true?

Still trying to figure out the exhaust thing (Really hoping Harold from Spitfire returns my call), may have to go with the "Laysons" set.

Am I on the right track? Any suggestion on what I should do different?
