They say everything is bigger in the Lone Star state, and when it comes to small-block drag racing engines that is accurate. TRE Racing Engines of Cleveland, Texas, took its experience building mega-cube engines and translated it into the small-block world, where the envelope is pushed by small-block niche racing classes.
These classes have taken the small-block architecture to a whole new level, as evidenced by the company’s max-effort, all-billet small-blocks.
“This is a design we came up with in house. It uses a 10.00-inch-deck block. It’s an all-billet design based off our big-inch, RVW nitrous motors,” Taylor Lastor, President and Engine Builder at TRE Racing Engines, explained. “We shrunk down what we found and ended up with the huge Radial vs. The World motors and made a small-block with stock bore spacing.”
Retaining the stock, small-block Chevy 4.4-inch bore spacing, these engines maximize bore diameter and stroke within those confines to deliver up to 511 cubic inches.
“We also use a 4.625 stroke crank from a billet. We completely machine the cylinder head in-house for a week, each from a solid blank (with 2.300-inch valves flowing 500 cfm) with a special chamber designed for nitrous and a 15-degree valve angle,” Lastor explained. “It also has a 60mm tool-steel cam with 1.050-inch lift and .937 key lifters.”
Clearly, this is a no-holds-barred effort for racers at the highest levels, and engines similar to the one seen here have already had great success.
“Justin Curry has the first one, and we have one in JD Campbell’s X275 Camaro coming out for testing,” he added. “They make 1,050 on motor and another 750 horsepower with a .056 jet.”
With displacement larger than many big-blocks and design optimized for performance, these engines will surely expand the expectations of how a small-block-powered car can run on the drag strip.
