Anyone seen the new car craft Demon Project car?

LS engines are no cheaper to build and offer no distinct advantages over the latemodel Hemi.

Disagree! They are cheaper to build and the aftermarket support is significantly larger for the LS than it is for the Hemi. In addition, aftermarket support for the Hemi probably won't go too much further because a lot of the Mopar guys are not interested in paying the costs associated with the support. Costs are high at first and start to come down when the R & D is recovered I know this for fact because I'm trying to get some things for the Hemi that are available for everything but the Hemi and vendors are not willing to do it because the development costs are too high compared to quantities they will sell at the prices needed to recoup their costs. Supply and demand is king and we in the Mopar world have a reputation for demanding until the price tag is shown.
