Performance & Mileage

Big displacement means lots of torque, but it also hurts fuel economy. Expect 10‑15 mpg in city driving for the older iron‑block giants, while the newer supercharged LS9 can manage around 12‑14 mpg combined. The modern 6.4 L Hemi is a bit kinder, delivering roughly 15‑17 mpg on the highway.

Price & Rivals

When these engines were new, they commanded premium prices. The 8.0 L Cadillac cost over $15,000 in 1994, while a brand‑new C6 Corvette ZR1 with the LS9 sold for about $100,000. Today, a well‑maintained 426 Hemi muscle car can fetch $30‑40 k at auction, competing with modern V8s that rely on forced induction rather than sheer size.
