Ok. So I've finally come to grips with having to ask for help. I don't like it BUT...the alternative is experimenting with expensive components. Too much money. I'll try to make this as short as possible to prevent any attention span issues. I'm looking for suggestions for transmission, etc. to fit my particular needs. Keep in mind I'm new at classic American iron (sue me, lol) but not new to cars. Feel free to dumb it down as much as you feel needed, I'll speak up if you're making me feel TOO dumb. Ok:

Facts: '65 w/ 327, TH350, 10 bolt (3.73's), Suspension-basically stock AFAIK,

Where I want to be: 90% Cruiser, 5% Auto Cross, 3% Drag...I can add. Hangs with today's performance cars.
12's or better, 450-550hp for arguments sake.
MAST Motorsports LSx engine (power AND mpg's)
Overdrive transmission (considered Bowler and TCI for programmability...$$$) 700r4, 4l60e,4l65e,4l803, etc., who knows...
12 bolt (considered Currie or Moser) but not sure about gears.
Problems I'm anticipating: Wanting to run Kore 3 Z06 brakes and 10" wide rear wheels (fitment), keeping it auto and still keep decent performance.
(think Automatic Caddy CTS-V)

Short term compromise: 327 w/ mild cam, headers, exhaust system, electronic overdrive transmission (if possible), rearend-x, all for decent power to get me by.
1. Transmission first, right? Or rear first?
2. What transmission?
3. Why and from who? I really need an explanation here. Opinions are fine.
4. If I AM able to run an electronic transmission w/ the carbureted 327, will I be able to utilitze electric gauges. I hate the bouncy mechanical gauges.
5. Notable mention...the car will run Air Ride suspension.

Replying to my own post. How stupid. Sorry for the wordy first post. Plain and simple I'm wanting to pick a transmission that will keep me in the sporty cruiser feel. The above info may be TOO broad. Sorry. Help me if you can.
Well...I have to be honest. I have been researching my butt off and really wanted Jake's well as others, but figured I'd post up my mess so that I could get answers from the group also.

Jake, I've looked at your website a couple times and for some reason I missed the engine section half the time. (I looked though). So basically you can mimic the Mast setup? I wish your shop was in Fort Worth. I'd come trade some volunteer work for knowledge. Haha. Going to go check out your site a little more.:thumbsup:

Will, I haven't narrowed the rear yet but am looking into it. I hate I have to do it but pretty sure I'll have to for 10's considering the wheels will tuck deep into the wheel wells at certain points of the day. :D
