If an engine is bored .30 over what does that make the actual displacment?

 

it might add 5ccs possibly..

my blaster bored .060 over was a 205...

 

Uhh....do you mean 30 thousandths(.030) or 3 tenths(.30)....3 tenths is a third of an inch...

An R motor .030"/.75mm oversize, 66.75mm would be 252.0cc's/15 cubic inches.

An R motor .3"/7.6mm oversize, 73.76mm would be a 306.3cc/19 cubic inches.

 

Thanks that's what I wanted to know.
