I heard pierce has been running a big one from vic hill for the last few years that nobody else can get.

Is it safe to say that's a "clean air only" kinda engine?

Pretty sure Rumley has one at least that big. Vic Hill was running a 480 11 years ago.

My guess is JD, but that’s an absolute pure guess

I heard on Dirt Tracker's show that someone is using a 490 cubic inch Cornett. Who?
