More Info on Engine Blocks ? Options

[Beakster]

I have two 1.7 engine Blocks

the one in pieces Case n# is EA064290

The other in the car is EB005450

Would anyone have more info on engines by the Case numbers ??

All Type four cases are basically the same with small differences.

-some very early 411 cases were mag and had no windage tray provisions, very rare.
-bus cases have different drilling for dipstick, oil fill, fuel pump (carb), lifter pressure relief (late cases not drilled),etc.
-similar differences as bus for 411/412 cases.
Biggest issue with using bus or 411/412 cases in a 914 is the dipstick tube.

For 914 the only difference in the 1.7,1.8, 2.0 cases is where the serial number is. I don't know for sure but the euro carbed 914 may have the fuel pump area machined for the mechanical pump.

The 1.7 "E'' cases are a great foundation for a build go

1.7/1.8 are the often best cases for any build, the shorter stroke crank is stronger and has less flex than the longer 2.0 crank, therefore causing less wear to the case.
