Wrong Engine Captain America

While sitting here readin' some news I happened to click through a few photos on the news links about a Captain America movie. What struck me immediately is the fact that here is this bitchin' lookin' army bike and wow, whaddaya know they put a modern motor and tranny in there instead of actually getting maybe a K or P series motor from S&S that would have nailed the look, been modern and completely on point. Surely the purists will be raising their fists as well, being that the devil is in the details. Damn if those bad guys don't have some cool street fighters...
