900+ HP Naturally Aspirated LS on an Engine Dyno | NO NITROUS | RS Garage

In this video Jay and Job Spetter tune a 450 cubic inch LS based engine going into a 1969 Camaro. We run the engine on the EIC Motorsports Engine Dyno making over 900 HP from the Naturally aspirated V8. The engine uses CID Cylinder Heads, has a 15:1 Compression Ratio. It has a 4.1" Stroke and 4.185" Bore. It has Kinsler Stacks with eight 70mm Throttle Bodies. During the dyno test the engine was running One R Ethanol fuel.

Thank you for watching.

Damn I LOVE high rpm high hp ALL MOTOR engines.

Congrats! What a hell of an achievement!

Badass engine nice work glad to see the new channel 👍🏻

This is LITERALLY my dream configuration...but I'd want a little more displacement and an LT billet block instead of an LS. I'd go with both direct AND port injection - you get incredible part-throttle, low-speed drivability with really good top-end power and flow. And it sounds fucking NASTY! But 670 lb-ft out of 450ci is incredible. That's 91 lb-ft/liter! For reference: the classic 458 F136 V8 engine made 88.5 lb-ft/liter and the LT6 in the C8 Z06 makes 83.5 lb-ft/liter.

Nice! 122hp\LITER\BAR.. impressive 👌
Most ls based stuff is lucky to break into the 100's.

Keep your turbos or blowers, nothing beats throttle body noise.

I recognize a Yates head when I see it.

[EnglertRacing]

For comparison sake. All of the top sprint car engines are 410" and make 960hp with icky pinch port sbc pattern heads and turn 9300rpm

Damn I missed vids with Jay congrads on the new buisness

[lanegeisewite]

SBC powaaaa!!!! Shouldve keep a LS7 head or BBC style canton valve cylinder head on her

[TheTkrum]

Very very cool. How much to make another?

[DavidB]

List some part numbers for all of this so we can check them out. And check prices.

[elektro]

That's based on a Cleveland head, not a Windsor, correct? How do the flowbench numbers compare against an appropriately sized LS rectangle port head?

7:05 I went from ls1 to ls3 heads and a short runner intake on my 408 ls and chop at idle got a lot more aggressive . Am I safe to assume this is why?

[mikemcleroy]

Where can I get a set of those heads?! 😅

[beachboardfan]

WTF is this a second real street performance channel!?

[Metalwolf]

Is that 15:1 static or dynamic? Caught that it’s on ethanol, not pump gas. What application really calls for something like this? I love it but I don’t get the why.

[drcolster]

I'm a bit confused, why use the Ford head, there are so many LS heads to make 900-1000 hp with the same or less effort...The cost of going this way with the custom heads must of been a lot more expensive... Can you tell us the reason ???

[lifesgifts]

Its awesome but its still a chevy abomination 🤣

[magnusdanielsson]

Whats the reason behind adopting a ford head for an LS?
