273 Performance build possibilities.

Wow thanks for the replies! Very cool to see the compression ratios and peoples experience. Certainly a lot to read and think about here.

@4spdragtop I suppose 300-400 hp/tq range. Much easier if I just get a blueprint 408 build. A friend of mine (who builds cars, but not the engines themselves) thought it could be interesting to build a high RPM 273. That got me thinking about it.
But I think if it comes out a penny less than 300 if not 350 it really wouldn't be worth it.
My google searches have not really resulted in much examples to reference.

There is also the idea of being able to alter the power output using a turbo or supercharger or nos. Idea being a quiet driver vehicle most of the time, but it can (somewhat) easily open its exhaust plus increase the power. How much? Honestly, enough to at least surprise a modern middle of the road v8 muscle car I.E. 2020 Mustang. 2016 Challenger. Enough to feel the car move in to a nice level of snappy power.

@66fs Thanks! The car has a mild 318 and a 4spd a833. Keeping it like this for a while and driving the car, but am considering ideas for a drivetrain overhaul including TKX 5-speed and new rear. But i'm debating on the purpose of the car. There is an idea of keeping the car a driver, but wanting some power, or ability to get more power. Drivable enough I could start it right up and go get groceries, but enough power to have a bit of fun.

"Beating a 350 Chubby with a 273.....yeah, that does if for me." Hah! Exactly!!! Also btw to clarify when I say "stupid" I'm mostly meaning my lack of knowledge of whats possible or how viable. I don't really know much about this in particular.
