Lets assume that I had the resources (aka money) to build a project engine lets say I build an inline or horazontaly opposed four cylinder with an absolutly insane 7 inch bore and 6 inch stroke, we would have over 800 cu in displacement, and about half the surface to volume ratio as a 5.7L V8, mathamaticly speaking we could put it in a camaro and run highway speeds at or below 700 rpm, in addition to the crazy low opporation speed we would have an exisessve amout of power just a downshift away, I know that an engine with pistons that size and a stroke that deep probably would come unglued past 4000-5000 RPM, but the upside is that you would probably never need any more revs than that since hp is just a multiple of torque (torque=hp at around 5200 rpm) even if could only make 900 ft-lbs (a conservative figure for our project engine) and we maxed out at 3500rpm we would still be making over 600HP!!! I don't think weight would be a problem with this engine, we have about the same surface area as a small block v8 and the LS2 fully dressed weighs less than 400 lbs, so it is not out of the realm of possability to make our project engine a comprable weight. This engine could not be made street legal because of emissions laws, big bore/long stroke engines tend to have a problem with unburnt hydrocarbons, but with the advent of gasoline direct injection, and multi pulse injectors, not to mention the use of E85 a street legal engine of this type might be possable. Does anyone out there in internet land see any problems with a project like this?
