The GM LS engine is great, just the absolute best. Itâs hard to say with total certainty, but itâs probably one of the most used engines for swaps, or at least a very close second the original Chevy Small Block. This engine platform is magical, and seems like it couldn’t get any better âŠunless you could get it in a V12 formation, and thanks to an Australian-based company, now you can!
Boasting that you can âTake your build to the elite level,â V12LS.com has you covered if youâre ready to go all-out with your LS build. Basically, the build is two LS1 engine blocks combined into one. The 9.5L V12 engine made its worldwide debut during the 2016 SEMA show as a prototype in a 1967 Camaro, this version made 641 RWHP.
Now that the company has put the engine into production for consumer use, the one-piece block could possibly be used to make a 1,000 horsepower, naturally aspirated powertrain with the same bore and stroke as a GM LS1. Available as a cast or aluminum block, the engine packages start out at $21,300 with delivery included, and youâll get the block, camshaft, crankshaft, and cylinder heads. From there, options get more complete, and more expensive. If youâre looking for a drop-in powertrain, youâll be shelling out $46,200, youâll just had to find your own accessories, headers, and water pump.
Installation actually seems pretty straightforward as even the engine mounts are the same as the LS1 engines youâll find in original V8 form. The biggest trick about this engine would be figuring out how to put it in whatever car you choose. This V12 LS1 is nearly 9â longer than a factory LS1, and all that length falls at the front of the engine.
We would vote for the bare option since you can do a lot of things with 580 cubic inches, but we still have a lot of questions about sourcing parts. What would you do with one of these V12 LS1s?
