The Michigan-based company, which specializes in racing cylinder head development, is currently ready to ship the foundation components — cylinder block, cylinder heads and intake manifold — with the necessary dimensions to support a 600ci displacement within the somewhat traditional confines of the 58-year-old SBC platform.
“In all practical purposes, it’s a next-generation small-block,” CFE’s Larry Gadette tells EngineLabs. “It’s what Chevrolet should’ve done 20 years ago.”
The project is so new that information remains limited, and only one photo is available. EngineLabs will update this story as more news is released, hopefully in the coming week.
The new 600ci architecture is an extension of the current big-inch efforts that have escalated in recent years with improved billet-block design and machining techniques. Aftermarket engineers can now enlarge dimensions and map out near perfect geometries and clearances, then program that data into a CNC machine and produce perfectly aligned blocks and cylinder heads.
“We really didn’t start out to develop a 600-incher,” explains Gadette. “We started developing a 572ci engine that was more proportional and conducive to making high-end power.”
Here’s the GM R07 cylinder block with 4.5-inch bore spacing and improved cooling dynamics. It helped pave the way for aftermarket blocks with with bore spacing stretched over the traditional 4.400-inch standard.
The original customer wanted a big-inch engine based off a block with 4.5-inch bore spacing. He already had a crankshaft with a 4.900-inch stroke.
“We started doing some research and thought, if he’s got a 4.900-inch arm, all we need is a little more bore and we’ve got 600 cubic inches,” says Gadette. “It was spawned from that.”
Concluding that a number of markets would salivate over 600ci — which equates to 9.83 liters — CFE moved forward on designing a block with 4.6-inch bore centers and expanding its famed SBX cylinder head to support the wider cylinder locations.
“It’s only .475-inch longer than a traditional small-block,” reports Gadette. “It fits where a small-block fits and it looks like a small block.”
The block, which can ordered with or without water jackets, sports a 4.400-inch bore. When combined with a 4.900-inch-stroke crankshaft, the resulting displacement is 596ci, but it’s possible to poke out the cylinders to 4.500 inches.
“The bore size will support 662ci,” says Gadette. “So it’s almost possible to reach 700!”
