Launch RPM for a 4 Speed?

[Chevy454]

What was your MPH? That will tell the tale of how good your engine is...also, you need your timing in a lot earlier...all in by 2k would be nice. Carb stuff...Eric would be the man to talk to, the bog could be from a number of things, wrong jetting, float level, fuel slosh, etc...

Also, if you value that KQ at all, get it the heck out of there...I've seen people twist rear ends on drag radials and even street tires...rare, but it happens...you have to realize, the track is prepped to hook, so you're gonna find the weak link in your drivetrain, I promise!
