How does a 454ci cup car not make more than 690hp? Even the 358ci little boys unrestricted make north of 750hp.
Hence why i am confused that the 454ci monster in that cup car is barely tickling the 700hp mark.An unrestricted cup motor is capable of over 900HP.
These are not traditional Nascar Cup engines. They're Track Attack custom engines (and cars) designed for track use but are not restricted by Nascar rules. A 454 isn't even allowed in Nascar. Their Chevrolet Performance LSV454 base package (with 6-speed sequential trans) delivers a durable and reliable race package, but there are other powertrain options available.

Thanks for the additional info, and the video. I'm a Hendrick fan so the video was fun to watch.@CobraBob and @SID297 are correct.
It's a GM 454 LSX crate motor that has been hopped up by Ilmor Engineering and converted to dry-sump. It made 600 rwhp on a dynojet at 6200 RPM. Redline is 6600 RPM.
A CUP motor goes up to 8800 RPM and requires an exhaustive maintenance program, plus is an insanely expensive option like $50k. Just starting a CUP motor is a chore. You have to use an electric heater to get the oil up to temp and then hand prime the oil pump with a drill, put the belt on, and then you can start it. No problem with a professional team, but a real pain in the ass for a a guy running a few laps during a track day.
Hendrick builds them at the same quality as their competition cars, which is nothing short of amazing.
These are my friends cars. I just did the video editing. I've tagged along to Hendrick Motorsports several times during the build process. If you are near Concord, NC or passing through, I highly recommend touring their facility.
Long video, but you can skip around if you are interested in seeing one small part of their facility.
Put the real deal NASCAR 358ci in there and I might actually click on the video
I noticed the same thing. Definitely a very distinctive sound that really grabs your ear, and then your soul.It's got that unique NASCAR sound even though it's different. Cool Vid.
