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.
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.
This Bronco came with a part-time four-wheel drive system and a V-8 under the hood. You could choose from a 5.8L 351M and the 6.6L 400. A C6 automatic transmission came standard or you could pick the optional 4-speed manual. This is the last generation of the Bronco to have a solid front axle, making it great for off-roading.
As if that wasn’t enough, GM then throws on a gargantuan 2.9-liter Whipple supercharger pushing a full 16 PSI of boost. All of that cast iron and forging means strength, and the COPO 350 can set dragstrip records day in and day out without breaking a sweat.
On paper, the Toyota Sienna seems to offer everything. It is roomy and has plenty of cargo space. Unfortunately, what looks good on paper isn’t always good in real life.
The Highboy was available with a 360 V-8 or the less powerful six-cylinder. A C6 automatic transmission was a common choice on the Highboy. Its tough look makes these trucks pretty collectible so they can be hard to find and sort of pricey for a fully restored version but if you have the budget, it’s a great choice if you are looking for a cool old ford truck.
Surely you’re aware of the C7 Corvette. You know it’s a huge leap for Corvettes. You know that valets go joyriding in them. You know a manual Z06 did the Nurburgring in 7:13.9, making it the fastest factory Corvette to ever lap that track. You know that with a little fiddling the C7 Z06 can exceed 200 mph. But did you know you can buy the beating heart of a C7 Z06 and put it in any car you want?
Like the old COPOs of the 60s, the 2011-14 models adhered to strict NHRA guidelines. That meant super-small production numbers and a price payable only by professional race teams. It also meant the car’s engine could only make 530 horsepower. But much like the Japanese engine restrictions of the 1990s, that figure seems to have been framed in air quotes. In 2016 a (not extensively) modified 2014 COPO Camaro ran an 8.323-second quarter mile at 165.80 miles per hour. Doing the math, that car was making closer to 1200 horsepower. 1200.
The alternative is to either rebuild an old engine yourself, have an engine builder do it for you, or buy a custom-made engine directly from an engine builder. Each of these options has a fair share of hurdles, and often it’s cheaper to order a crate engine than it is to go those other ways.
It also favors a hydraulic roller camshaft instead of the original’s flat-tappet cam. It makes a few extra ponies over the old model, too: 480 horsepower and 490 lb-ft of torque will melt any tires this engine’s hooked up to.
It has 113-cc intake ports, 2.25-inch intake valves and 1.88-inch exhaust valves, a massive 1150cfm carb (yes, a carb), a solid-roller cam with 0.714 inches of lift, 12:1 compression, and it requires 110 octane fuel. Here’s GM’s succinct English translation of those stats:
GM has been producing small-block and big-block engines for decades. Throw a few extra parts on one of these bad boys and you’ll be burning tires in no time. Before we talk about the best GM crate engines, let’s start by answering a few basic questions. Ooh, shiny. (source)
A big block has higher weight and density in the block, as well as larger valve bores, a longer stroke, and a generally larger exterior size. A big block can have the same displacement as a small block, but only the most extreme small blocks encroach on this territory.
