A a stock 6.0 with a cam good tune and long tubes is a 500 hp combo. You will have more money tied up in just the heads to get a SBC there.

Except the LS didn’t exist when Chevy produced the original ZR-1. The DOHC motor was based on the LT block.

I understand it’s the exact opposite purpose of all this aero, but this thing seriously looks like it is capable of flight.

That you design engines makes this comment even more disconcerting. There is no DOHC engine on the market that outputs the same or better amount of torque, HP, mpg, reliability and ease of maintenance in a package that is as compact and lightweight as the LS series. Do I even need mention cost?

Or, you could, I don't know, actually pay for content you value, and support the further creation of said content. Just sayin.

Ahhhhhhhh!

Packaging is important. Chevy could have gone DOHC years ago, but they decided an OHV motor produces similar numbers in a MUCH MORE compact package. That translates into lower CG and more opportunities to improve aero. Go look at how low the dry sump LS sits in a new ZR-1 and you will understand why the engineers…

So replace this

I wish every millenial ricer V8-basher would see this picture and banish from their warped minds the hoary old cliche of the “BIG OLD AMERICAN V8”.

Just to emphasize it’s compactness, here’s a 6.2L LS3 next to a 1.8L Mazdaspeed Miata motor. (note the LS3 is also sitting a little higher)

I’m curious about which engines you’ve designed. Care to share?

packaging and weight are super important. That being said, the only reason the LS is so ubiquitous in the aftermarket is because the traditional hot rodders won’t give up their pushrods. It was an easier update for them than say....the Mod Motor.

IRS and disc brakes in the 80's, too.

Not exactly space, but ICBMs: Project Pluto...which was a nuclear-powered ramjet to be used in ICBMs.

Zambian space program is pretty out there. From 1964.
