2012 Boss 302 in NHRA Stock Eliminator

You don't see regular production cars from Chevy, Dodge or Ford, because they would be terrible combinations. Old cars were rated differently (gross hp) from the factory with no engine accessories and free-flowing exhaust—new engines are rated with everything in place, including emission controls.

The real problem is that it is much harder to get 200-250 hp out of (non-supercharged) new cars once built for Stock. The new Boss 302 is rated at 444 hp and I have seen about 390-400 rwhp on a Dynojet chassis dyno. These cars will run 12.0s at 113 mph with sticky rear tires. We tested a 1970 454 LS-6 Chevelle (auto), factory rated at 450, and it was a good-running example, not a turd. It made 296 rwhp (I would guess it would have made 330-350 rwhp with a stick). I don't remember the torque numbers, but the BBC did make loads of torque.

Once modified for Stock Eliminator, you now have equal (or close to equal) drivetrain, suspension, the same advantages in regards to head mods (valve job), and camshaft, exhaust, etc. You can use all new parts for the 454, just like the 302 (or Chevy LS or Dodge equivalent). They are essentially rated the same, yet the Boss gives up 152 cubic inches!

I would guess that a properly built 454 LS-6 or ZL-1 427 Chevy (or 426 Hemi) makes upwards of 680-700 hp. Could a 302 equal that? Remember, this engine is already making 1.47 hp per cube! This is not a Ford thing, as I'm sure same holds true for the 426 hp Camaro and the 425 hp Dodge.

At 700 hp a 454 is making 1.54 hp per cube
At 700 hp a 302 is making 2.31 hp per cube
