That’s right, in the GM Performance Catalog of crate engines an 8-liter V8 is considered “small”. With max revs set at just 4500rpm, the Vortec 488 is a mill designed not to power the car you’re racing, but the truck you’re hauling it with. With 375 horsepower and 475 lb-feet of torque on tap at only 3200rpm, the 488 can tow that high-dollar enclosed trailer without breaking a sweat. Or it could pull your boat, your cattle, your neighbor’s house, or the grandstands at your local dragstrip. You get the idea.
A removable top made the Bronco a perfect choice for sunny days and a retractable rear window that disappeared into the tailgate was added for this generation. A folding rear bench seat ups the cargo space so you could easily haul plenty of gear into the wild.
This isn’t the 350 that your neighbor pulled out of a C10 truck and slapped a hot cam into. No, this is a 110-octane-only race crate engine built exclusively to win races at the local 1320. GM advises that the LSX454R comes with no warranty and is “not for road use”.
They mechanically lock the rubber to the rim so that sidewall sag from less than stock psi doesn’t drop the bead and leave you stranded. An added bonus to these is that their distinctive look adds to the curb appeal along with other Jeep mods.
Let’s start with the 9.1:1 compression, which means you can run this on pump gas. Add in a cast aluminum block, titanium valves, and a forged steel crank attached to forged titanium rods attached to forged aluminum pistons. Top that off with hydraulic roller cams, aluminum heads, and a high-helix supercharger pushing 10.5psi of boost.
The Chrysler Town & Country is basically a rebadged Dodge Grand Caravan with some added tech and comfort. Even in its lowest trim level, the Town & Country offers more refinement than a Dodge Grand Caravan. Still, as used minivans go, there are better models on the market today.
Enter the LT4 crate engine. Power comes on fast: a 1.7-liter Eaton supercharger spins at 20,000 rpm to force 9 pounds of boost into this 6.2-liter engine. That results in the same 650 horsepower and 650 torques you’ll find in the Z06 that’s sitting over at your local dealership, but for a fraction of the price.
If any car was worthy of carrying the original ZR1’s torch, it was that one. The numbers are huge: 638 horsepower and 604 lb-ft, with 90% of peak torque available from 2600 to 6000 rpm. Translation: lots of power on tap, whenever you want it.
