If it's any help I have a gd 1581 sohc motor avail c/w all ancilaries, basically a long-stroke Uno block, out of Punto ELX90, which can be built up into Punto GT spec I believe - am I wrong? It has a Punto-type 5sp box, with bellhousing that mates to the Uno block, which I might let go too - or it cd prob be mated to a Uno box.
