Default Ordering a transmission

I am getting ready to place an order for my transmission for my '78... I read on here somewhere that TH350s for Corvettes are a Corvette specific transmission. Is it not just a 6 inch tailshaft and bolt right in?
This is the transmission I have in mind, But now I am uncertain if it will drop right in. http://www.summitracing.com/parts/TCI-311000/
Any help is appreciated, and the sooner I have a solid answer the sooner I can be back on the road again :-)

the 78 trans. is not corvette specific & the # you mention will bolt right up. i recently replaced mine with a B&M #113001 from summit. no installation problems.

You do of course know, the mentioned TCI unit is a bit beefed up semi race unit. Since you're starting from scratch I'd check around a bit, for a 700R4 or 2004R od unit. 700R4's are more common with a lower 1st gear, but will require a shorter drive shaft, and cross member mounting work. The less common 2004R should drop right in. Of course there's gonna be some shift linkage/TV cable adjustments, but will be all worth it, droppind highway cruise rpm 30%. I haven't used a non od transmission in years.

The level 1 is $200 less for up to 350 HP. You will need to do some minor mods and need the TV setup.

Put an overdrive transmission in it, if the old one is shot anyway.

Awesome thanks for the info guys. I ordered the transmission. I stuck with the Turbo350 that I posted. I am changing the rear gears to 3.70s and I live on the island so an Overdrive tranny isn't really necessary at the moment. Not to mention I'm ready to drive this thing the day the tranny gets here, so I don't feel like dealing with shortening the driveshaft, adjusting the TV cable PERFECTLY changing the crossmember and so on. I want to just drop it in and go! If I decided to change my mind down the road I'm sure I can make a short project out of it.
