The main difference between an LQ4 and an LS2 is an iron block, which means these can hold tons of power. They’re famous for being a cheap way to get insane stats, and this hot Chevelle gained world fame In 2016 from an article at Hot Rod by throwing down 800 horsepower. That’s thanks to 16 psi of boost from a single 80mm Borg Warner turbo. The builder says “getting sideways in third or fourth gear is no problem” – we’re not surprised.
Or you could stuff one of these used engines in a hearse and set a world record.
GM 3800 V6
Unless you’ve been living under a rock, you know that used engines from Pontiac sedans can fit in just about anything that uses a transaxle. It’s also one of the most common used engines in the world with over 25 million produced to date. It’s been rated one of the best engines of the 20th century, so yeah, it’s reliable.
One of these powers pretty much any old Buick, Oldsmobile, or Pontiac with a V6. Bonus points if it’s beige.
