My 5.8 was rebuilt and bored .030. What is the actual cubic inch of my engine after being bored out?

 

Roughly 358ci. If it was decked a little less, if the heads were cleaned alittleless. And if you had your crank ground to 30 under, a little more.
but very little more or less.

Cool. Since i had the heads cleaned i can say i have a 357. I need to get liscence plate that say 357 MAG now.

 

Pam....Unless a crank is offset ground, as in a stroker motor, then the size of the engine doesn't change. Not even a little. Usually a crank is turned about.010", and it's ground on the same center as stock. As far as the 357 Magnum goes, that's what my friend named his boat, after having his 350 cube engines bored .040".
