According to Novak Adapters, the TH350 weighs 120 lbs.
just about any Chevy trans, a TH350 or a TH400 are the most common and will both fit. as far as engines and transmissions with Chevy's there just about all interchangeable without to much messing around. only difference with a TH350 to a TH400 is that a 400 will take higher horsepower/torque. but for most stock applications a TH350 will be fine , oh and the TH400's are slightly longer to.
The th400 is a much stronger transmission meant for heavy duty use while the th350 is meant for normal use.
If you're talking about the length of the driveshaft, the front yoke should go into the transmission all but 1 inch.
