The ThunderV12. Turn Key HP Engine $24,900
Our signature engine. A true ThunderV12! The HP long block plus HP oil system, Dual carbs, distributor less ignition system,3hp modern style starter, GM bell housing adapter, 100-amp alternator, water pump and laser cut exhaust flanges. This engine comes on a stand and has been tuned using the settings we gathered on the dyno abusing our in-house dyno mule. We run the engine prior to delivery to set the chokes and check systems. This is a running engine! Simply the highest power crate engine you can buy between 2,000 and 3,000 rpm that is naturally aspirated and runs on 87 octanes. And it is an ultra-rare V-12 to boot. Yes, it should cost more.
Example of recent full build
Engine with 5sp overdrive trans and dual disk clutch.
The engine is a rare low time unit that ThunderV12, LLC has stuffed full of our signature parts. The core engine was easily a top 10% core. In other words, if you attempt to build such an engine yourself, you will need to buy 10 engines to get one this good.
Strength comes from the custom ARP fasteners. Power comes from the custom Hot-rod Cam and twin Holley style carbs. Reliability comes from the custom high flow oiling system based around the Peterson Fluid System hi-volume dual feed pump. Upgraded valve train components assure years of trouble-free performance.
The flywheel and clutch are from McCleod. Here we have a twin disk unit that optimizes 800lb-ft of holding power with low pedal pressure. Twin disk units are commonly only found on supercars. The bell housing is a Chevy style unit from Lakewood.
The transmission is a 5-speed overdrive TKO 600 from Tremec Transmissions. These transmissions have proven themselves both on the drag strips and the road courses around the world and should provide faithful service to a hot-rod for many years. We would not recommend this transmission for vehicles of excessive weight or for pulling heavy trailers. Our personal experience with a TKO behind a 700hp, 660lb-ft BBF with slicks has been flawless for over 70,000 miles of track and street use. The .64 OD ratio is simply wonderful on the street.
The engine ships with a chrome 100amp one wire alternator and (4) precut 1/4" exhaust flanges to aid in fabrication of your custom exhaust.
