It’s The Battle Of The Tiny Drag Cars

Unveiled in 1972, the Fiat 126 served as the replacement for the original 500, and as such, it is a very tiny car. It had an appropriately tiny engine as well, but the following video shows a couple of 126s which have had their engines replaced. The red car is from Taz Racing, and has a Chevy V8 stuffed in there somewhere. I'm not sure exactly what’s powering the blue car, just that it’s a “Toyota twin-cam” engine. The exact specifics aren’t known, and neither do I know how they got those engines to fit.

But it’s safe to assume that they’re now a bit quicker than stock.
