What Roger said with some addition. The "wedge" combustion chamber was further unique in that it was not formed in the cylinder head as per most engines, it was formed above the piston in the cylinder itself. Imposed some additional performance mod restrictions. These appeal to a fairly narrow market for all the reasons noted, so don't expect a long line of interested folks. You can research on places like ebay and craigslist for what market price is, though on c/l you only see asking......but if the ad gets old it's too high. My guess would be $1-200 range if there's no scary sign to the engine. As for the trans, it was on the market for about 3 years and earned the none too complimentary slogan "slip and slide with turboglide". Do you have a boat that needs a small anchor?
