I like the idea. However I may be way ahead of the curve on this for my reason. Up here in Canada we're shelling out $6 per gallon and up for gas. It makes you think twice about building your stroker and is why I kept a 383 in my 70 pickup rather than building something bigger for it. I had to re-use the stock pistons in a slightly sketchy bore because of the lack of piston choice.
I do note though that most states guys are building without regard to fuel economy, due to gas being lower priced there. So good luck with it, not sure if the market will make it a success or not.
