Simple conversation starter:: What would it take too put DOHC 2.7 heads on a 3.5 block. Not planning on this build (...yet) but didn't see anything when I searched this topic and thought I'd throw this out there and see what happens.

Cannot imagine how this would work without extensive re-engineering/making new parts/etc

How could you switch a chain head to a belt?
Do you have time and money, as well as skills with Autocad or Solidworks? If yes make a computerized model, then cast some aluminum and get everything bored and surfaced on a CNC milling machine...

Is 2.7 and 3.5 bore the same?

And water pump somewhere else!

Head and block construction very different. Bolt pattern completely different, never mind the other stuff.

Completely different engine but can it be done on the 2.0 4cyls installed in Neons?

Installing a 2.0L DOCH head on a 2.0 SOHC block. As I said, different engine, that's just out of curiosity ;)

Wouldn't it make more sense to look at other manufacturers that utilize a DOHC v6 set up? Then at least it may already run a belt set up.

Or as it has been mentioned, a lot of money and a large block of aluminum could be CNC machined....

I'd go for a 4.0 stroker with forged internals and strengthened 3.5 heads. Then twin turbo it.

A decent sized single turbo will flow just as good, if not better than a pair, also reduces complexity of the exhaust and intake, especially if you wanted to add an intercooler

These ideas sound better.

I find it hilarious how people go nuts when someone spends exorbitant amounts of money on their cars aesthetically, but as soon as someone brings up ideas to stir the pot for performance, spending as much money, people shut it down.

This is an idea that is entirely possible, just need to look further outside the box. And there will be an excessive amount of parts you won't end up needing. I know when we put the turbo on my car we purchased a lot of stuff that never made its way onto the car and now will sit on a shelf not needed, but such is the life of hot rodding.
