I have been having a problem with my RPM slow to rise at WOT. I can top it out at 4800 at wideopen, but once there it slowly will raise another 2-300 RPM over the course of 20-30 seconds. Of course I would like to have this RPM if not more without the delay, and am somewhat disturbed as to why it does this.
I have a 82 eliminator daycruiser with Pre-Alpha, 21' prop. Small block 350, Alum heads w/ roller rockers, comp xtreme cam, bg carb 750, stealth intake, all MSD. Dyno's at 415.
Any ideas?
