How about the flywheels? Do they exchange between the small block V8 and
big 6? Of course I have a set (bell housing and flywheel from 240-6) up on
a shelf and could check myself except the 289 stuff is at the machine shop.
The bell housing to block pattern is not the only matter with bell housing
interchange. You must also have the right gearbox pattern for the
transmission you plan to use too. There are two patterns, on that fits
the toploader and one that does not. Some bell housings are drilled for
both, some have holes for one type and bosses that can be drilled for the
other, some only fit one or the other. There is some controversy about
whether or not you can safely drill and tap the bosses in aluminum bell
housings but I know of at least two people who have done so with no
problems so far.
