I believe it's around in the 11.0 range..

You sure you wanna go LS/VTEC ???
your gonna build up that motor and it's not gonna last for very long ...
you will be bummed in the long run and I know you've heard about LS.Vtec's not being reliable/ lasting very long.

you'd have more fun with a B16A block w/GSR head
