Anselmo Motors/Murdovsky Tempest engine/Guminator1A Version

The Anselmo Motors Tempest is a family of V8 and V10 internal combustion engines produced by Anselmo Motor Works with displacements from 4.8 L to 6.9 L. Originally, AMW developed the engine architecture under the name Allertor; the only engine at the time, a 5.9 L V10, was the first to be developed. Despite its smaller displacement, the 5.9 L was intended to compete with Ford's 6.8 L Triton V10, which was the only V10 engine used in commercial vehicles at the time. However, the cancellation of the 5.9 V10 in favor of the G149 5.0 L V10 in 2006 caused a four year delay in development. The latter engine was essentially a de-tuned 5.0 Lamborghini V10, with approximately 235 hp at 6,700 rpm and 370 lbf⋅ft of torque at 3,000 rpm. 
In 2010, Ivan Kavanaugh of Murdovsky Automotive acquired the Allertor V10 project from Anselmo Motors, renaming it as the Tempest. It's interesting to note that the Tempest internal name was inspired by one of Kavanaugh's preferred cars at the time of this development reset—a Pontiac Tempest. In spite of this, Murdovsky nor AMW didn't officially market the engines with the Tempest name in any production vehicle where they were used. The 5.9 L V10 prototypes were also inherited, but they were used as a benchmark for a clean sheet V10 design by Murdovsky. Ultimately, the Allertor V10 became the basis for the 4.8L Tempest V8 and the unrelated Sigma V6. 
== 4.7 L ==
The 4,771 cc (4.7 L; 291 cu in) displacement 90-degree V8 was introduced with the Anselmo Motors ML series commercial trucks for 2014, and replaced the LS-based 6.0 Gremlin V8 that was used previously. It is essentially an eight-cylinder version of the 5.9L V10. The engines were also offered with both aluminum and cast iron blocks, depending on application. The 4.6 L's bore and stroke are nearly square at 3.65 in and 3.46 in (92.9 mm and 88 mm), respectively. 
== 5.9 L ==
The 5.9 L; 364 cu in (5,964 cc) 90-degree V10 is a member of the Tempest family, which was originally developed from the odd fire variant of the Allertor V10. The original 2-valve version was first introduced in 2012, with a 3 and 4-valve version following in 2016. Three versions of this engine exist, with one being an odd-firing engine while the other two were even-firing. The latter two were developed independently by Anselmo and Murdovsky, the latter of which was ultimately the only design adopted as part of the tempest engine family. The Murdovsky V10 was a clean sheet design based on the 2.4 L Murdovsky M743 inline-4 petrol engine, despite this both V10s were developed for use in large trucks. Note that the article will only cover the Murdovsky even-fire V10 because the Anselmo engine is almost identical to the odd fire engine mentioned below.
===90° odd-fire V10===
The odd-fire V10 was technically the first engine in the Tempest family to be developed. This was to be Anselmo's first 10-cylinder engine since the BQ10FE in 1995 and the 1999 BZ10-GLU. However, the original design for this engine was retooled into the 4.8L Tempest V8 and the Sigma V6. 
===90° even-fire V10===
The creation of a new 5.9 L even-fire V10 was taken into consideration while design work on the rest of the Tempest family began in 2011. This was based on Murdovsky's 2.4 L M743 gasoline engine, and was primarily intended for use in heavy trucks and commercial vehicles. This version of the 5.9 L V10 was rated at 415 hp at 5,600 rpm and 745 lb⋅ft of torque at 4,300 rpm. It was also meant to rival the 6.8 L Ford Triton V10, which was still in production at the time. Bore and stroke size is identical to the 4.7 V8 at 3.65 in × 3.46 in (92.9 mm × 88 mm), although it shares the Ford V10's firing order of 1-6-5-10-2-7-3-8-4-9. The V10 also uses a split-pin crank with 72° firing intervals and a balance shaft to reduce additional vibration.
