Why not look at the LS engine? Half the weight, less than half the cost, mega more available in the aftermarket and can make twice the power at half the cost.
Yeah that is a fact. I looked at doing that exact thing, until I learned about these new Hemis. But yeah at one point I was going to do an LS swap for that reason. Changed my mind though, given that I can get an entire car for about $4-$6 with a hemi, so not bad at all.
