i need the cylinder volume for a 355 ci,in milliliters per cylinder now i have 717.25 ml/cyl is that a 350?need this info for ecm constants i went to the help file in tuner cat and it gave a formula to convert it and i could not get it right.any help would be great!confused:

 

According to my calculations, a 355 would be 727.176 ml/cyl.
The value you mentioned is correct for the 350.

 

BTW, these are the formula I used:

1 Cubic Inch = 16.387 mL. (1 inch = 2.54 Centimeters, 1 mL = 1 Cubic Centimeter)

355 CI * 16.387 = 5817.385 mL

5817.385 / 8 Cylinders = 727.17 mL/Cylinder.

 

thanks for the formula
