FAQs

Q?

Is the V12LS block cast-iron or alloy?

A.

Our new one piece casting is a strong cast-iron design, this is due to the high demand we have had for an iron "LSX style" block over the alloy.  We do have plans to release an alloy block, however due to the efficient design of the LS platform the iron V12 still weighs less than a big block chevy engine and the durability of iron is unquestionable.

Q?

What is the firing order of the V12LS?

A.

We use the same firing order as Ferrari and many others, which is just like two inline 6s with one bank reversed. For the full details on the firing order and angles please refer to this document: V12LS firing order

Q?

What is the price of the V12LS?

A.

Our long block is US$35k, including delivery to the USA or Australia.
Turn key engines vary in price depending on the options you choose.
Pricing on engine builder kits will be announced soon.

Q?

How can I order a turn key LS12 engine?

A.

We will be taking orders in person at the SEMA show in Las Vegas, or email: sales@v12ls.com

Q?

What is the block angle of the V12LS?

A.

The block angle of the V12 is 90-degrees, the same as all other GM LS based engines including the V10 LS. Each bank of our V12 is balanced independently as if it were a straight six, resulting in a well balanced engine overall. The V12LS runs odd-fire just like a Viper V10, has a rough idle and an exotic sound.

Q?

Will the V12 fit my project car?

A.

The V12 LS is 8.8 inches longer than a standard LS V8, making it around the length many straight 6s. Therefore the V12LS engine is well suited for conversion into many cars that came with a V8 or I6 option. See our product page for exact dimensions.

We also package the shortest serpentine drive system on the market with our turn key engines to help provide additional clearance.

Q?

Will I need a larger radiator?

A.

It depends what you have now, but we recommend sizing the radiator as if you were fitting a 700hp Big Block Chev.

Q?

Is this engine two blocks welded together?

A.

Our prototype engines were made from two LS1 blocks that were cut, precision machined, welded, heat treated, re-sleeved and line bored. This is possible because of the aluminum construct of the GM LS engines. This has proven to work very well however due to high demand for what is a lot of advanced machine work, we are now casting our own blocks. Any engines ordered from this point forward will be built using the new one piece casting.

Q?

What is the warranty on a long block or turn key engine?

A.

Six months provided the engine is not used in competition or fitted with boost or nitrous.

Q?

Can I get a custom grind camshaft?

A.

Yes, contact us at sales@v12ls.com with your camshaft specs and we will provide a quote.

Q?

What displacements are available?

A.
