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 ??

EA and E B engine cases are the same.
The EA engine was the 72/73 Rest Of World 1.7L engine.
The EB engine was the 72/73 USA 1.7L engine with slightly low compression and HP.
It was the pistons that were different to lower the compression.

Jeez easy to find anywhere ,use google..I do it before asking any question on what ever forum I'am on which is many and all rather different types of cars.
The 1.7 "E'' cases are a great foundation for a build go 96mm with 2.0 litre heads you will be good,but you really need to change the cam if not going to FI.

Why Google? That info is right under your finger. Top right corner of every page. It's called 914INFO.

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.

I saw a VW 412, 1.8L case that had the mechanical fuel pump that mounts to the rear of the case.

I edited my post above for 411/412 and "Biggest issue with using bus or 411/412 cases in a 914 is the dipstick tube."

411/412 used an early D-jet FI system in north america.
Bus had carbs till 75 and the mechanical fuel pump.

ea is a 73 1.7 Eb is for a 74 1.8
EC is the 1.8 case, both 74 and 75. EB is the low-compression CA-spec 73 1.7.
