Re: [FWDLK] Manifold interchange

[Bill Watson <wwatson5@xxxxxxxxx>]

To add to the complications with early Mopar hemis, each was built in low
and raised block versions, just like Chrysler "B" V8 engines.    Thus,
although the 325 engine was based on the same block as Plymouth's
241-260-270 engines, the intake manifolds will not interchange as the 315
and 325 engines were raised Dodge block engines while the 241, 260 and 270
engines were low block.  Dodge's low block engines used a 3.25" stroke while
the raised block used a 3.80" stroke.

Similarly, the DeSoto low block engines were 276 and 291 (3.344" stroke),
while the raised block version came as 330, 341 and 345 (3.80" stroke)..

Chrysler's low blocks were 301, 331 and 354 (3.625" stroke) and raised was
the 392 (3.906"stroke).

Raising the block deck increased the distance between the heads - thus the
intake manifold on a raised block engine is wider than that of a low block.
