Anyone willing to help me with some /6 questions?

[myrtle]

Just found a really good deal on a 1971 /6 3speed manual Duster, and I was curious how hard would it be to conver to a small block or even a big block. How hard would it be to swap in a 4 speed tranny? The little research that I have done over at slantsix.com slantsix.org tells me small stuf like torsion bars and brakes, but that was mainly for small blocks.

If anyone has a good link, article, or information on swapping out the /6 & 3spd manual for a Big Block 4speed drive train Id really love to see it.
Thanks alot.

There isn't much more to say because its a fairly straight foward swap, its already a stick car but if its on the column then you'll need a floor hump. The rear needs to be changed out as its probably a 7 1/4 which usually don't hold up even to the leaning tower of power. Keep the K-frame you have now and use the Schumacher pieces because theres never been any stress on it, the rest is cake, good luck.

  you'll need to swap to atleast an 8.75, remember that finding a body 8.75 is possible but they usually hit you deep in the wallet.   you may also have to beat the firewall back a little, id rebuild the entire suspensionn, mainly the front with polygraphite kit fro mjust suspensions to help handle the add wieght and power of a big block, some subframe connecters would be a decent idea too. then to help it hook, id run SS springs or even a 4 link,  course all these suggestions will depend on your budget and how big you are going.
