Quote:My calculator tells me that an A15 with a bore size of 79mm & a stroke of 83,5mm [1.5mm stroker] yeilds 1637cc & that's stretching an A15 pretty severely.
Any production based 1600cc two valve pushrod engine that produces that much power, unblown, is going to be pretty much undriveable at anything much less than full song.

After my own experiences with A series engines, I would say that very few people could hope to have such an engine professionally built for anywhere near the asking price. At 10K [NZ?] it's damn cheap.

"Absolutely no expense spared" I do not doubt that statement for a moment.

For a comparison, check out Pitroad for their competition engine prices.
