Depends upon class, the Cup engines are as you heard a lot different take a peek at the link for early ROx <<< ::: MaxChevy ::: GM's R07 NASCAR V8 - 05/15/07
Flip a page to see the combustion chamber really, really tight.
The SB 2.0 and 2.2 have moved down in class. Keep in mind that the SB engines like the ROx are designed to breathe into 9000 RPM and more providing sustained power at that level, not just bounce the tach to 9000 then retreat to somewhere lower. So these parts are not very streetable if that's what you have in mind.
