Big block trans on a small block

Even though I run a 727 (bought a van with a 360/ 727) there has been LOTS of talk here, buys running considerable power successfully through a 904, so don't discount "that good deal" just because it was a 904 and not a 727

Do be aware that the external balanced engines like the 360 came with weights on the torque converter, so if you get one like this, you'll either have to remove the weights or change the converter for your 340. No biggie.

The 727 is a little longer than the 904, so you'll need to do some driveshaft work.
