This Late Model Engines build is centered around Concept Performance’s new LTR block, which is the first aftermarket as-cast aluminum Gen V LT block.
The Chevrolet LT engine family from General Motors is rooted in the early ‘70s, when the LT1 was featured in the Corvette and Camaro Z28. After a 20-year hiatus, GM reintroduced the platform in the early ‘90s. The “LT1 350” came out in 1991, and was distinct from the high-output Gen I LT1 of the 1970s. It displaced 5.7L (350 cu in), and was a two-valve per cylinder pushrod design. The LT1 used a reverse-flow cooling system, which cooled the cylinder heads first, maintaining lower combustion chamber temperatures and allowing the engine to run at a higher compression than its immediate predecessors.
Lead times are no longer months upon months as they were in the middle of 2020 and throughout 2021, but the situation is still of some concern, and it’s forced engine builders to get creative at times.
LS swaps are popular for many reasons, but there are a lot of variations and details to sort through – more of them than you may expect – and many of them are associated with the intake manifold.
Whether you’re scouring junkyards, ordering cores, investigating factory options, looking at aftermarket cast iron or aluminum blocks, or spending big bucks on billet LS blocks, you’ve probably noticed it’s been harder to find exactly what you want for the foundation of your LS build than it historically has.
Closed-loop control can be programmed to either add or subtract up to a certain percentage of fuel in order for the engine to reach the target air/fuel ratio.
Guys like Cody Helms of HDP Performance prove that being competitive in diesel motorsports doesn’t have to be a pocket-emptying hobby. His 12-valve Cummins build made enough power for him to race competitively in the 5.90 class at UCC this year. Check it out!
Choate Engineering Performance, located in Bolivar, TN, does a ton of diesel engine remanufacturing and custom engine building. We were recently visiting the shop and got the run down of Choate’s 6.7L Powerstroke build. It’s our Diesel of the Week!

The 3.0L EcoDiesel is known for its incredible fuel economy and low-end torque, not necessarily for its high-horsepower capabilities. But that won’t stop some from building a formidable Pike’s Peak race engine with both turbocharging and supercharging. Check it out!
The team at Kill Devil Diesel does some amazing work surrounding all light-duty diesel engines, but the Poplar Branch, NC-based shop specializes in Ford Powerstroke work. As such, they do a ton of trick stuff on 6.0L Powerstrokes, and we got a first glimpse at a billet 7.0L/6.0L Powerstroke build for Charlie Fish of KC
