It will NOT bolt to *any* other engine. The bellhousing pattern is specific to the engine family it was designed for. A TH400 or TH700R4 behind a 454 Big Block Chevy will not bolt directly to a small-block Chevy, a different GM engine family, or an engine from a different manufacturer (Ford, Chrysler, etc.).
To use that transmission with a different engine, you would need:
* An adapter plate: This is a custom-made plate that bolts to the transmission and then to the new engine. These can be expensive and may require custom modifications.
* A different bellhousing: Sometimes, you can find a bellhousing designed for your new engine that also fits the transmission. This is less common than an adapter plate.
In short, while the transmission *might* be adaptable to other engines with significant work and expense, it's not a simple bolt-on affair. You'll need to identify the exact transmission (TH400, 700R4, 4L80E) and then research adapter plate availability for your target engine.
