Big-block Polaris quad – Click above to watch the video after the break
With a little blood, sweat and some good ol' American ingenuity, almost anything is possible. Whether or not "possible" equals "advisable," well... we'll leave that up to you to decide. In any case, at least one enterprising individual has apparently managed to stuff a big-block Chevrolet engine displacing 454 cubic inches inside the tight confines of a Polaris ATV.
There doesn't seem to be any rear suspension on this quad, so those massive balloon tires will have to suffice. While a smooth ride might be problematic, power won't be. After all, not only is there a 7.4-liter V8 underneath, there are also dual carburetors and long-tube headers. For ultimate ease of use, there's a Turbo 350 automatic transmission slid in between the engine and solid-axle rear end.
Yes, there's a video of this beastie in action, and no, the driver is predictably not wearing a helmet. He is, however, enjoying the protection afforded by his apparently ill-fitting cap... that is, until it blows off his now unprotected head. No worries, he'll swing right back around and put it back on to save his noggin. Safety first! Watch it all go down in the video after the break.
