v12 ls1
Actually bonecrusher if you look very closely I believe it is actually a V-12. in the lower left hand corner you can just barely see the red spark plug wire for the 6th cylinder on that side of the engine.

Verdad Gallardo the suburban was in a small corner at sema. I nearly missed it. no one was looking at it because it looked stock. The owned built it. He started with 2 ls1's
and cut 2 cylinders off of each one. he welded the blocks together. The guy said that the only thing that he had made for it was a crank and cam. everything else came for the 2 ls1's. guy said that it makes 525hp in stock form. He drives it all the time and couldn't be happier with it. It looked factory. Probably the coolest thing I saw at sema.
oh the guy also said that it will spin all 4 tires.

How did he do the intake and the heads? seems a little more complicated than welding two blocks together. Would'nt he have to have an intake and heads made for it? If he did all that work damn. nice job.

I've only seen this done one other time. A few years back in an issue of Engine Masters (a once a year issue of PHR) there was a guy that cut the ends off of a Hemi top-fuel motor and made a V-twin out of it for a land speed car. It had the shortened 14-71 blower and everything. Estimated 1200hp.
Anytime. Do some research on FACTORY efforts to create motors by "cutting off cylinders" and see how well (durable) they worked.... If any worked at all (4.3L comes to mind), they eliminated middle cylinders (not end) and the most durable ones all had to employ balance shafts to smooth them out..
Complete waste of time and money.

Its actually doable. When I saw this the GMC V12 engines of back in the day came to mind. Check this link out.

I'd imagine its alot of work and while I dont think its practical, I can appreciate the effort and know how that goes into something like that.

One of my friends went to SEMA and called me up when he saw this. I couldn't believe it, but he had pictures and said he spoke with the guy. My friend talked to the guy and was told virtually the same things as eviltwin_1987.

Nice try, but better luck next time.

Ford's GT90 engine of 10 or more years back used 2 Duratec aluminum blocks EB (Electron-Beam) welded together to make a V12, look for Ryan Falconer's gen2-based V12's (although he makes his own blocks/heads) etc. Lots of fun to be had if you got the skill & $$!! Take a look at youtube video of machining a V8 block complete ... just get a big chunk of aluminum, high-end CAD & CAM software ... go for it!

Except these aren't those....
So I think you know where you can look for the luck you need to make an argument...
If that motor lasts 10,000 miles before eating itself up, I'd be amazed...
