biggest bore?

[joukaishou813924]

just got bored and wondered what is the biggest bore you've ever heard of for a gasoline engine?
I say gas engine because i know diesels can get into the feet to yard range for bore....

I donno about car's but even from a car engine this motorcycle engine has one of the larger bores I think I've ever seen. 215 ci. from 2 cylinders. 6" bore x 4" stroke with Hemi main and Rod bearings:

I'd hate to do an oil chance on that one .....275 gallons?!?!?!?!

 

[joukaishou813924]

allright i'll throw another ruling in there, lets say gas car engines, i know a bbc 502 or 572 come with around 4.56" bore and a dart block goes up to 4.625", anyone heard of a street vehicle with a larger bore than that?

That's a big one, but it's not a gasoline engine. It's fueled by natural gas.

bore

I ran a chevy 400 sb from a blazer for a while...the bore was so maxed out..from the factory...the water jackets were too thin and overheated all the time..keep in mind...i put a new water pump and pulled out the thermostat...still she overheated...
