If you have to ask why anyone would shove a 427 into a Nova, we can't be friends.

Only 10 survive today, and this one's headed to the auction block. If you want to buy it, it's one of the feature lots at Mecum's January 2015 Kissimmee auction. Bring money.

The L72 427 V8 had 11.0:1 compression and allowed the Yenko SC427 Nova to run sub-11-second quarter miles. Zero to sixy was a shade over 5 seconds.

Pre-auction estimates for this immaculate car are $400,000 to $500,000. Given the rarity and the quality of this restored example, that's not outlandish.

This SC427 Nova has a black interior, rear bench seat, and AM radio. With the thunder that 427 likely makes, the radio seems like an afterthought.
