Hey all. I know E series heads have been fitted to A series blocks before (mainly looking to fit to an a10/a12. Does anyone have more info and pics on exactly how this is done. Really wanting to know how they setup the timing belt, timing pulleys, water pump etc.

I have not heard a single report of how it is done

I heard that some have swapped the entire E13 engine into a 1200

I have fitted an e15et in a 1000 but im trying to make this a legal street car so I was thinking of trying to keep the a series bottom end and using the e series top end including injection. I can either go a boosted a10 or n/a a12. From what I read is u have to tap a hole for the timing belt tensioner, plumb up the front block water pump gallery and run an external water pump. I managed to pick up a complete e15et head with injection for $20 ($15usd lol). I just dont have a block here to try it all out on atm

I had a couple of A-series blocks that had been modified to accept the E15ET heads. There is a huge amount of work here. There is a picture somewhere on the site of how the timing belt was done. From memory the tensioner for the belt was attached where the A12 camshaft inserted into the block. It was a custom plug with a stud on it. In addition to that the blocks had various water galleries plugged and I seem to recall some of the push rod holes. These blocks were strictly for racing. I had my fabricator look at the project and we determined it would be easier to simple for an entire E-series engine.

be easier to convert your A10 to a flathead or sidevalves
then add boost to it to get back to factory hp of the ohv
