Q?

Is the V12LS block cast-iron or alloy?

Our new one piece casting is available in cast-iron with a 4.125" (LS7) bore or aluminium with a 3.065" (LS3) bore. For most applications we recommend the iron block.

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?

How can I order a turn key LS12 engine?

A.

Contact us at sales@v12ls.com to place a deposit and you will have a V12 engine shipped to your location within three months.

Q?

What is the bank 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.

No, only our prototype engines were made from two LS1 blocks that were cut, precision machined, welded, heat treated, re-sleeved and line bored. We are now casting our own one piece blocks.

Q?

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

A.

12 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.
