A Chevy turbo 400 will bolt up to a Chevy 400 engine just fine.
A BOP (Buick, Olds, Pontiac) turbo 400 will not bolt up to a Chevy engine.
The bellhousing is different between the Chevy turbo 400 case and the BOP turbo 400 case.
Another option is a J-W Performance ultrabell which can be used with a Chevy or a Buick, Olds, Pontiac engine, but this requires the transmission case to be modified in order to use it (The original bellhousing must be cut off and the case prepped, then the ultrabell bolts on with the front pump bolts).
Yes but be sure to use the 400 small block flex-plate/flywheel for balance purposes.
Yes, as long as the transmission has the Chevy bolt pattern.
Yes, if they were built with the standard Chevy bolt pattern.
As long as it has the Chevy bolt pattern, yes.
As long as the TH350 is from a Chevy....yes.
yes
You can if it has the Chevy bolt pattern.
No turbo 350's in 1992.
no
Yes it will bolt right up.
yes
All chevy 350 engines use the same bolt pattern to bolt the bell housing to the block so the 71 model block should bolt up the same although there may be slight differences otherwise.
YES, That is no problem, it will bolt right up.
