Mate i got a pulled apart 1600 long block complete. I'll even throw in a box of new pistons for $150 (no barrels or rings).

Your choice of dual port of single port heads. The motor came with single port heads.
I bought it for $550 on the Action day before last (engine) and pistons for $40 (NOS brazilian). It was a working 1600 but had not been moth-balled properly and so I stripped it down for a rebuild. This is as far as i got before i bought an ally case and gone for a turbo, bored, stroked project for my baja. Its just sitting in my shed consuming space. At least its in a state where you can really inspect the components and see if it suits you.
Thanks,
Chris.
