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 Hotrod Cam and twin 500cfm Barry Grant carbs that have been custom tuned with annular boosters just for us.

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  such as the $140,000 Ford GT. The bellhousing 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 roadcourses around the world and should provide faithful service to a hotrod 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 50,000 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..

This engine is runnable on the shipping stand prior to sale.

Payment and Shipping

Reserving Engines 

The GMC 702ci V12 cores that ThunderV12 relies on are of a limited supply.  When the usable cores are exhausted, ThunderV12 engine production will conclude.  When that will happen depends on core supply and engine demand.

Reserving an engine for 2011 production requires a 25% deposit.

Reservations may be cancelled but $1,000 of a reservation is non-refundable.  

Following engine production, ThunderV12,llc intends to remain as a parts, repair and V12 parts clearinghouse. 

We look forward to a long relationship.

 Shipping

We prefer engines be picked up in person at ThunderV12 LLC's dock in Evansville, IN. The engine can be run for the customer prior to loading.

Engines are on shipping frames that easily fit in a pickup truck.

We load all engines via forktruck.

With that said, ThunderV12, LLC has working relations with several freight companies and can ship engines anywhere in the US. If trucklines are used to ship your engine, ThunderV12, LLC will only charge our actual freight cost to your location.

There are two packaging options for engines shipped via common carrier (LTL).

• We can ship the engines on the frames as-is for no additional packaging fee but we transfer all liability for shipping damages or theft to the buyer.

• Option two is an additional $500 packaging fee and ThunderV12 will package your engine and accept liability for any freightline damages or theft.

We can only accept  liability for freight damages if engines are shipped pre-paid by us. Customers arranging their own shipping assume all liabilities of shipping.

             Payment

 ThunderV12, LLC will not release any engine that has not been paid for and cleared by our bank. Checks will have to wait for clearing. Wire transfers can be set up at the buyer's bank and executed quickly when the time comes to ship.

   SALES TAX

All engines to Indiana customers or shipped to Indiana addresses will be charged 7% Indiana sales tax.
