cam and trans?

I've decided to go with a 393 stroker kit for my 69 Cougar. I'm looking at a hydraulic retro fit roller cam. What do you recomend?
Also, I want a manual five speed, what do you think is the best option? Gforce T5? Tremec?
I already have a set of trick flow heads for it, full MSD, 3.89 gears, locker rear end. Air gap intake and 670 Holley carb...

3K is kind of a steep buy in for the Richmond...

I already have the T5. I'm willing to sell it off to offset the cost, or get it upgraded somehow. I was hoping to be able to finish my 5 speed swap for around a grand, as I have almost everything else. I have the hyd stuff, the bell, the pedals. I don't have a good "T5" cross member, and may have to shorten the drive shaft. but that will be later.
The car will only see the track a couple of times. If I can get a legitimate "100 mile an hour club" sticker, that will be the last time it goes to the track. I'm working on three of these cars, and would like to get on with my life. Finish paint and interior, you know how it goes.
But I don't want to do stuff twice from a lame first effort..
I know not of the Gforce T5, or the astroglide thing. I've heard good things about tremec. However, just because I'm not going to race it everyday doens't mean I won't spin the tires at a stop light or two, or three or .....

I'm also willing to look at a custom cam, but do I have to get the retro kit first, and then the cam?
This is my first planned stroker motor, so a lot of this is new..

I have a 715 Holley on the shelf for the 69, and I have a 750 laying around somewhere.

The roller conversion is just a spider in the valley, isn't it? To hold dog bones in place for the lifters? I'm thinking somewhere in the .550 lift range for the cam. I have to get the part number for the heads so I Can verify those numbers again...
