Rev limiter
Have a MSD 6AL, with the old cam rev limiter chip is 7000.
New cam is a Doug Herbert mechanical roller RPM Range: 2500-6500 Advertised Duration: 285/285Duration @ .050: 242/242Lift: .567/.567Lobe Center: 110c.
Should new chip be 6600 or 6800..
Going drag racing next week, so I should change to a new chip. What's your opinion...Thanks Jack

Think I'd leave the chip where it is and just shift earlier....unless you're shifting on the chip???Yesterday is history, tomorrow is a mystery, Live for Today!

Learning must be difficult for those who already know it all!!!!
I tried rubber isolators between the frame and pump, but it made little difference. I don't mind spinning the motor over to refill the carb(s), it allows time to build oil pressure, jmho..
