Overdrive Options

I understand that in a peformance application you got to pay to play, but with a average daily driver type car in the 300 horse, 350 tq. range, can something along these lines work? Using the earlier mentioned 200 4R.....

Core.....$200 ish.
OH kit...$300 http://ckperformance.com/200R4_rebuild.html
Shift kit $135 http://www.summitracing.com/parts/TRG-200-4R-HD2/
Trans guy, on the side..$200
Wilcap Adapt...$575
Rebuilt lockup conv..stock type...$150-250.
Driveshaft mods & incedentals.....$400 ish.

I understand that it requires alot of labor & some fab on the owner part, but do you guys really think a senario like this isn't doable?

And for the record, i would never spend this kind of coin on a regulation, street driven "A", because the cost vs savings will be a loss on 90% of the conversions...in my opinion. There's always exceptions, but gear ratio, torque converter & tire size would be way more cost effective.

That's a pretty decent rundown. (Your prices may vary... :) )
If you look at it from a strictly financial point of view, yep, conversions rarely make any real sense. Then again, does pouring money and all your spare time into an old car make any sense? The thing of it is, the OD trans swap adds a versatility and drivability to our old rides. I've done auto and manual, 4, 5, 6 speed conversions. It's almost never a totally low buck, plug and play install. (There are few exceptions). There are pros and cons to whichever route you choose to go and only you can make the deciscion as to what best suites you.
