車輛詳情為2012款雪佛蘭考維特Z06，Centennial/Z07版本，搭載代號LS7的7升V8自然吸氣引擎，OHV配氣機構，每缸兩氣門，非直噴，無VVT(可變氣門正時)，峰值功率505馬力，匹配6速手動變速箱，車輛自重1450公斤，風阻係數0.35，輪胎規格為前285/30ZR19，後335/25ZR20，型號是米其林Pilot Sport Cup ZP。車上除駕駛員之外無乘客，也沒有大件行李，滿油箱，胎壓設定為出廠值，全程車窗密閉，外界氣溫24攝氏度，空調設定在22攝氏度並全程保持開啟狀態。地點選在美國德克薩斯州休斯頓周圍，從休斯頓南部的Manvel市殼牌加油站出發，途徑TX-288，I-610，I-10到達休斯頓西部的Katy市殼牌加油站結束，沿途43.5英里(70公里)；這段路程以限速60-65英里每小時(97-105km/h)的高速公路為主，也包含一小段市區路程。測試時間選在晚高峰時期，其中嚴重堵車路段在圖中以紅圈圍出，這時的高速公路儼然密密麻麻首尾相接的停車場。長度大約相當於總里程的一半。即半程高速巡航，另半程嚴重擁堵。測試方式為在起點加滿油，里程錶清零，出發；到達終點時再次加油，測得車輛實際油耗表現。在暢通的路段以65英里每小時(105km/h)的速度巡航，其餘路段皆採用較溫和的駕駛方式，以能平穩保持當前速度或滿足當前加速度需要的最高擋位行駛，全程無空擋滑行，減速時盡量避免踩剎車，採用帶擋滑行方式，其中每次轉速回落至1000轉時採用轉速適配法降擋，最低降至2擋。經過上述測試，車輛在43.5英里的路程中實際消耗燃油1.642美製加侖，相當於26.5MPG，即百公里8.8升。另外車輛在保持105公里每小時的速度巡航時，行車電腦上顯示車輛的瞬時油耗在34MPG左右（隨著路面的上下坡實際在31-37之間變化，主要保持在34），相當於百公里6.9升。
新一代(C6) Chevrolet Corvette Z06使用的LS7 OHV V8是GM第四代Smallblock OHV V8家族的新成員，由於工作還不夠穩定，GM暫時棄用了全新的具有VVT和歇缸系統的雙凸輪軸三氣門配氣機構，依然採用了傳統的兩氣門缸蓋的設計，通過7升的排量達到了6200轉時500馬力,4800轉時644的扭矩輸出。
A Dry-Sump(干油底)技術，大大降低了引擎高度，使得引擎可以安放得更低矮從而降低整車重心，並使得較小的機艙可以容納更大功率的引擎。並且由於這種潤滑設計不是從極底的機油盤收集機油，所以不會出現車輛機動過於激烈時機油被甩向四周，導致潤滑系抽不上機油的問題。而且沒有機底尺寸限制，這種系統可以容納更多的機油，象LS7就使用多達7.6升的機油。這類系統通常還有專用的機油收集泵，所有機油泵都容易採用獨立的動力驅動，實現和引擎轉速的分離，從而保證任何時候引擎都能夠得到充分的潤滑。
B Pressed-in缸襯代替Cast-in-iron缸襯，增加了缸徑，幫助排量從6升增至7升的同時，依舊共享原有的缸體框架，Pressed-in缸襯將制活塞嵌在其內部，維修時要更昂貴，但是快捷，一換都換。
C 連桿和Ferrari 360的V8一樣，採用了鈦合金，強度重量比大大提高，使得高轉速下的響應大為改善。
D 依然使用兩氣門缸蓋，但液壓挺桿和搖臂系統經過改進，響應更加靈敏，並且所有的氣門搖臂都採用獨立的搖臂軸，而不是通常的同軸設計。這樣氣門的安放角度要自由得多，優化了換氣效率。
E 排氣門延用了LS2的液力成型鋼管設計，內部充鈉，進氣門則乾脆採用了鈦合金。不但更輕更冷，提高響應速度，也幫助引擎將壓縮比提高到11。而且鈦氣門使得單一的進氣門可以做得很大。實際上LS7雖然升功率不能和高轉速的多氣門DOHC引擎相比，但比之普通的多氣門引擎卻不算小，這也是因為其兩氣門構成的換氣面積已經相當接近常見的多氣門引擎。
F 排氣歧管不是通常的鑄鐵材料，而是鋼製，但和普通的改裝件中常見的不鏽鋼排氣不同的是，它是液力成型工藝一氣呵成的，內壁的光滑度使它帶來不少的功率。
I 複雜的高流量進氣系統保證它在LS2基礎上每分進氣量又增加了25%，使功率從400馬力得以提高到500馬力。紅線還在7000rpm以上其實DOHC V8，V12有四根凸輪軸，60度V8，V6，V10還要另加一根平衡軸，氣門多意味著相應的驅動裝置也多，這些都會帶來額外的系統開銷，OHV的開銷相比之下就是多了推桿，所以如何縮短推桿就是個問題推桿的材料沒有找到資料，按傳統來講，應該是鋼管，但因為改裝市場上有鈦推桿，所以我也不能排除LS7使用了鈦推桿的可能性實際上LS7在成本方面考慮，材料到不如上代LS6極端。周年紀念版的LS6連排氣都使用了賽車引擎的鈦合金材料一般的缸套是Cast-in的，而不是Pressed-in的。Pressed-in只在柴油機里較流行，材料多為鋼(當然會是專用類型)或銅，它Cast-in要薄，但是你不容易把活塞從中取出來。（文/自殘刀盲血）
The GM small-block engine family is an engine design intended as the only V-8 engine used in General Motors" line of rear-wheel-drive cars and trucks. The GM small-block series was a "clean sheet" design with only the rod bearings in common in terms of shared parts with the classic Chevrolet small block V8. The basic layout owes a good deal to the essential concept of Ed Cole"s original small-block design of 1954-55, though the small-block engine also uses design cues from Buick, Oldsmobile, and Pontiac engines. Some small-block engines are all-aluminum, especially the performance oriented engines, while others are cast iron.
*note: to be perfectly clear, Gen I v-8 engines are Chevrolet while Gen II and up are GM small-block engines.
The small-block engine has been the main powerplant of the Chevrolet Corvette from 1956 to 2015 and has seen use in a wide variety of other General Motors vehicles, ranging from sport coupes to full size trucks. Due to the engine"s relatively compact external dimensions compared to its displacement and power output, the engine family is also a popular choice for engine swaps, import cars, kit cars, hot rods, boats, buggies, and evenlight aircraft.
The LS6 designation was also used on a 454 CID Chevrolet Big-Block engine of the 1970s, as well as an iteration of the GM Iron Duke engine from the late 1970s
The LS6 is a higher-output version of GM"s LS1 engine and retains the same capacity. The initial 2001 LS6 produced 385 bhp (287 kW) and 385 lbf·ft (522 N·m), but the engine was modified for 2002 through 2004 to produce 405 bhp (302 kW) and 400 lbf·ft (540 N·m) of torque. The LS6 was originally only used in the high-performance C5 CorvetteZ06 model, with the Cadillac CTS V-Series getting the 400 bhp (300 kW) engine later. The V-Series used the LS6 for two years before being replaced by the LS2 in 2006. For 2006, the Z06 replaced the LS6 with the new LS7. The LS6 shares its basic block architecture with the GM LS1 engine, but other changes were made to the design such as windows cast into the block between cylinders, improved main web strength and bay to bay breathing, an intake manifold and MAF-sensor with higher flow, a camshaft with higher lift and more duration, a higher compression ratio of 10.5:1, sodium filled valves, and a revised oiling system better suited to high lateral acceleration.

LS6 intake manifolds were also used on all 2001+ LS1/6 engines. The casting number, located on the top rear edge of the block, is 12561168. Applications:
2001-2004 Corvette Z06
2004–2005 Cadillac CTS V-Series
2007 SSC Ultimate Aero TT
S7 can also refer to a 454 over the counter 460+ hp high compression engine Chevrolet Big-Block engine of the 1970s
The LS7 is a 7,008 cc (7.008 L; 427.7 cu in) engine, based on the Gen IV architecture. The block is changed, with sleeved cylinders and a larger 4.125in (104.775mm) bore and longer 4.00in (101.6mm) stroke than the LS2. The small-block"s 4.4 in (110 mm) bore spacing is retained, requiring pressed-in cylinder liners. The crankshaft and main bearing caps are forged steel for durability, the connecting rods are forged titanium, and the pistons are hypereutectic. The two-valve arrangement is retained, though the titanium intake valves by Del Westhave grown to 2.20 in (56 mm) and sodium-filled exhaust valves are up to 1.61 in (41 mm).
Peak output is 505 hp (377 kW) at 6300 rpm and 470 lb·ft (640 N·m) at 4800 rpm with a 7100 rpmredline
[citation needed]
During GM"s reliability testing of this engine in its prototype phase, the LS7 was remarked to have been repeatedly tested to be 8000 rpm capable, although power was not recorded at that rpm level, due to the constraints of the camshaft"s hydraulic lifters and the intake manifold ability to flow required air at that engine speed.
The LS7 is hand-built by the General Motors Performance Build Center in Wixom, Michigan. Most of these engines are installed in the Z06, some are also sold to individuals by GM as a crate engine.
After an extensive engineering process over several years, Holden Special Vehicles fitted the LS7 to a special edition model, the W427. The HSV-tuned engine produced 375 kW (503 hp) and 640 N·m (470 lb·ft). The W427 was unveiled at the Melbourne International Motor Show on 29 February 2008
[12]
and went on sale in August 2008. The first Australian car to be fitted with this engine, however, was the CSV GTS of 2007, which was claimed to have a power output of 400 kW (536 hp) and 600 N·m (440 lb·ft).
