Help with engine displacement calculation

[Teksid281]

Sorry if this is the wrong forum but I didn't know where else to put it. I am looking up what a 298ci stroked 281 would be considered if it were also bored .20 over. I found a calculator and the stats on a 281 to find it would be a 283, but looking at the math I don't think that would make a 298 a 300 (sorry I know I suck at math.) So I was wondering if anyone else who is good at stuff like this might be able to help. Or is this even a desirable thing to do? When I purchase the stroker kit from Livernois I don't know if I want to go stock bore or .20 over, so I was just weighing my options. Any help would be greatly appreciated.

P.S I did look on their website for stroke specs on the 298 kit but could not find any

Oh and I'm kind of assuming it will be a 302? I could be way off though.

From what I calculated the stroker kit increases your stroke from 3.54" to 3.76"

The when bored 20 over (not 0.2" over ;-)) you'll be left with 301.4ci

Heres my math if anyone wants to check it

Displacement = pi*((bore/2)^2)*stroke*number of cylinders

After your stroker kit

298 = pi*((3.55/2)^2)*stroke*8

solving for stroke = 3.763

now at 20 over

Displacement = pi*((3.57/2)^2)*3.763*8

which = 301.4

Actually your both wrong, its .020 over. when you hear someone say "20 over" its short for saying 20 thousandths over stock bore;-). Going .2 over would be making the bore almost a 1/4 inch bigger:uh oh:

Edit: NVM LOLasaurus I see what you meant now :bash:

Sorry I was just typing it up in a hurry and forgot the first 0. I know its not .20 cause there wouldn't be any cylinder wall left :burnout: Thank you very much for the calculation man, it will be hilarious to tell people its a 301 :lol:

It took. .020 seconds to google this...

Calculator for CID

maybe you should have used those 0.02 seconds to read the original post.

He couldnt find the exact stroke specs for the 298 stroker kit :banana:

No problem :beer:

BTW if you somehow managed to bore it 0.20" over

you'd have yourself a 332ci

cool.,., that's what I'm gonna do :beer:

The winner. OP, just call it a 5.0.

Hell yea bro then I can shit on all the 324s!!!

Except that 301.4 is only 4.9 liters, just like the old 302s.
