He said it ran good...not as much top end as the modded V-Spec........ However its not really fair to compare yet, the GX7 had very little fuel thru it and was extremely tight, as well was running full shims and a weighted flywheel.... He said it ran good considering, but just wasn't showing the crazy power he is used to.... But as I say its too early to tell....... The Go 7 5.5 we are running has 2.5 gallons on it, shims removed and it absolutely screams.
