Quote: This is an interesting thread. I have 273 heads on a 318 Duster. Has identical mods as yours and I ran a 15.9 (at 5000ft) with it. My next project is a 318 Volare that I'm going to put 273 heads on. I'm going to use the 2 barrel single plane intake that goes with the 273 heads and see what kind of mileage I can sqeeze out of it. I just like those 273 heads! They are lighter too and they don't seem to crack or warp like the 302's
I have a good friend and engine builder that is a class racer. He raced a 273 car years back and now races a 340 Duster. One can actually make the 273 scream. there's a Stock Eliminator racer by the name of Wong that races 273 cars and gets them into low numbers.
