Round up to 513 cid or down to 512?
What do you guys say? What does Dodge say?

Is it precisely 8.4L ?

I say that this has to be the ONLY computation that you'd carry out to 12 digits other than those that relate to certain aspects of a female.

Would you guys please be serious? This one single cubic inch is critical.

Mercedes calls their 6.2litre cars E63, CL63 etc. So I would bet they will round up with Dodge as well.

Go with 513.

What is the bore and stroke? With those we can calculate the actual CID. I would imagine that "8.4 L" is a rounded number.

Got the info.

bore x stroke: 4.055 x 3.96 = 511.407 cid (8.377 L)
Dodge rounded up the liters so we'll round up the cid.
So we will go with 512.
Thanks for all the help you clowns.

Hey, I was not "clowning"around, the 8.4L approx was important...
Thou mathematically, if the 8.37 is 8.4, the 511.40 should be 511...
512 sounds better.

That WOULD be me
...but the real question is:Can you really afford to round down?" LOL

Well, based on centuries of established arithmetic (which I keep reminding my young kids I that I actually do use every day – they just don’t understand ), if the bore and stroke are precisely as Chuck stated (511.407 cid), that would be rounded down to 511.
8.377 does round up to 8.4, but 511.407 rounds down to 511.
For those of us with '03-'06 SRT-10s (which Dodge calls "8.3L"), we have "505" impressed on the air intake box. I'm sure someone (Chuck???) will check the bore & stroke numbers, but if it is equal to or less than 504.44444444444444444444…. cubic inches, then Dodge is slightly over exaggerating.
Hey Chuck, I’m sure there is a point to this post – what other stock “off the show room floor American cars” have ever been/are over 511 ci (anyone know???)
