No doubt that technology has come to the rescue.
I had muscle cars in the 70’s/80’s and when the EPA put the screws to them I thought it was over.
When I sold my 440 six pack Super Bee I had no idea we’d now be able to buy something faster and......, has AC, power seats, cruise, gets 30 mpg etc.
After owning a deisel VW and reading about all the hybrids I wonder about the gas motors which no one is covering.
There is now an engine in production with variable compression ratio.
One of the car mags does an annual contest called Engine Masters that is one of my favorite reads.
They establish a base line and let the builders go.
What some of these guys come up with is amazing.
I am a huge fan of turbos but still want to see what you can come up with w/o it.
One of my hero’s, Smokey Yunick used to come up w/**** that just made people scratch their head.
I just went through the Garlits museum too and to see that progression in performance is amazing.
I remember building my 440 Chrysler and reading that the wrist pins were
offset in the pistons to reduce noise but increased friction/reduced power.
Direct Connection said to swap them from side to side, which I did.
W/all those tricks we guessed power at 500 from 440 Cu ins or 1.14 per 🤓

I race a Chev Cavalier in Chump Car endurance series with a couple friends
2.4L (145ish cuin) Ecotec naturally aspirated, stock internals, cold air intake added makes 160 at the wheels with a tune. No idea what the parasitic loss would be
It came out of a scrap car with who knows how many miles on it, and we have beaten the daylights (usually 7 or 8 hour races x2 in a weekend) out it for one or two race weekends a year for 5 years, no issues whatsoever

Yes, the Aston Martin is NA. Design team led by a Formula 1 engineer, so that's where the tech is coming from. Ten years ago Formula 1 used a 2.4L NA V8 that made 750 HP @ 18,000 RPM. That's about 5 HP/CID, but let's not get into that.

I have a Challenger Hellcat... Greatest selling point... it'll smoke the tires on the interstate at 70 MPH, but it can be docile enough to be used as a daily driver. You couldn't have this kind of versatility back in the Muscle Car heyday. Cars had a 90-day warranty; God help you if you blew up something at the track. So long as I do not mod the car, full warranty for 5 years/50,000 miles... and they encourage owners to beat on it at the track!
