Default Redline on L98

While driving my vette, i was doing a pull, and accidently up shifted into netural from drive, not overdrive and floored it, i hit 5900rpm on accident, i know redline is 5500, anything i should be worried about? Mind you I'm an 85 with the cast iron heads.

One point of advice...

Stop trying to manually shift your car. GM spent a lot of time, with a few hundred eggheads working 40+ hours a week on this very problem, figuring out where your car would shift on its own for best performance at wide open throttle. You're just going slower if you do it yourself.

So much so that Motorweek actually got a better quarter mile time in the AUTOMATIC than they did the manual in 1985. A good man behind the stick in a manual should beat an automatic, but it won't be by much and it's all won or lost at the launch.

I watched that review, was stunned the old auto beat the Doug Nash, another reason why i didn't mind taking an auto vette, i have the 3.07 rear end too which is nice

Put bad driving in a stick shift car, and it goes slower than the auto counterpart? Big surprise.

I have seen that episode too. The automatics in that era got you better times because the BW T10 was a stiff, hard to shift box with a narrow H gate, and after all the 4+3 box was just a T10 with an overdrive unit riding piggyback.
