The Engine in question is a Z11 bit is is a MarkI not a Mark II. Its a W based 409 with a bigger stroke crank in it. You can actually machine a 454 crank to fit in a 409.

WOW!! I'm surprised it took 15 pages for someone to register and make a post about something he/she obviously didn't have facts about or made up. Try harder next time.

I call this a "RTFM" moment. Read the friggin' manual. It prevents costly mistakes.

Default V12 engine.

Hi.

I just the V12 engine you guys built.Thats an amazing work of art.Thats gonna be popular for hot rods,engine swaps and street machines and boats and aircraft too.

I hope you guys will be able to make that available around the world.Its a great engine.You'll get some buyers down here in Australia so let the magazines hear about it.

Keep up the great work guys.I love the sound of a V12.I think you got yourself a big winner there.

Amazing work!

We just removed it. It doesn't work well with the aftermarket computer so we're just using a crank position sensor.

You sir can go pound sand in your ***.... If you don't know what that means use your google fu, but that seems to have failed you already.

To the OP nice work and sub'd!

Wow, just when you think you've seen it all... Think about all those kit car Lamborghini replicas that could actually have a v 12 in it now instead of a v8. Pure art, nice job.

We've been steadily working on the intake manifold. The manifold plates are utilizing stock port sizes and are blended in to become velocity stacks.

Also we started on the valve covers. We were debating on making them from scratch and engraving something on them, but this just gets it done sooner.

We are almost done with all the fab work. After fab comes paint!

Brian Macy figured we could push the V4 to around 325-350 horse with some head work, cam, and a decent size turbo

We're going to focus on the V4 after we get the 12 done
