thats awesome news for us LS1 guys. I know what my next motor will be. 4 inch bore and 4 inch stroke. Someone run that to see how many cubes that is. Should be like 396 ci or so.

Anyways heres a link to some new vette info
new vette

 

Pie times radius squared = area

radius = half of diameter

diameter = 4, radius = 2

3.14 x 2^2 = 12.56

area x length = volume

12.56 x 4 = 50.24 per cylinder

50.24 x 8 = 401.92 cubic inches

61.023 cubic inches = 1 liter

401.92 / 61.023 = 6.586 Liters or 6.6 Liters

 

Sweet man...damn good with the engine math.
402 cubic inches sound mighty good to me.
Right now I have an iron 383. Going to a 402 ci aluminum that is 90 lbs lighter and 20 more ci.....sweeeet!
900 rwhp and 3150 lb raceweight!

I just hope my current motor holds up until we start seeing these 6.0 alum blocks.

 

Heres an easier way courtesey of Speedomotive INCs web page.

BORE X BORE X STROKE X .7854 X # CYLINDERS =

CUBIC INCH DISPLACEMENT

 

Very nice!!

 

That works too but the .7854 in this case gives you 402.1248 Cubic inches. So its all fairly relative.

Technically there is no way to tell cause Pi is an unknown value, you can calculate it too 200 decimal places and it still keeps repeating.

Technically you could use 3.1415926535897932384626433832795 for pi which yield 402.1238 ci

However you should only use the same number of decimal places that you have accuracy in your machine tooling. For example the bore is 4.00 cubic inches but could be 4.0004 or 4.00065 or some other variable beyond your machining tolerances. So really you would have to know to what tolerance GM bores are measured.

 

:o

Can't wait to see them on the road

 

I want to know what heads they are using. oh yea....and I want one(or two)

 

stop with all the math!!!!!
