: : What is the differance between an A and B engine. Will a engine parts work on it.
: :thanks Bob: Bob,
: This is not a complete list but just what comes to mind right now:
: - B crank has larger journals for both mains and rods
: - B rods are larger for the larger crank journals
: - B block has a fuel pump hole on the right side
: - oil pan is different (includes part of flywheel housing)
: - head is different, combustion chamber design, water pump mounting (you can use a B head (marked with a "C") on an A engine.
: - head gasket is different
: - timing gear cover is different (timing pin hole is 18 degrees off)
: - water pump is different (3 holer)
: - manifolds are different but can interchange
: - distributors are different (B has centrifugal advance)
: - carburetors are different (larger venturi and throttle)
: - flywheel housing is different (two piece)
: other than these, they are just alike ;)
: The good news is that you can adapt the Model B engine to an A with a little work and is quite desired by some folks.
: Bratton's (800-255-1929) has some Model B parts listed in the back of his catalog.
: John Thankyou John this info is very helpfull. The engines
are too different for me.
