Why less cylinders?

[cRiPpLe_rOoStEr]

Nowadays, due to modular designs, many smaller-displacement engines with a lower amount of cylinders can share some internal components with other ones, just like the Vortec 2900 and the Vortec 3700, among others...

But if that's not quite crazy enough, they also have bored out versions 2.9L and 3.0L that make 450hp, and 500hp respectfully, and if you really want to go nuts they even make twin turbocharged versions that make up to 1000hp. Heaven forbid I ever win the lottery because I would buy a stack of them.

Good luck with that.

Q: Can I buy a H1 or H2 engine?
A: Probably not now unless you are an existing customer.

As of March 2012, the H1 and H2 engine technology has been sold. The new owner will further develop the technology for race applications and plans to offer it to other markets in 2013. Hartley Enterprises retains the rights to build these engines in limited numbers for select existing customers and special projects in the US. All projects are taken for 2013.
