What should i have my rev limiter set at when i have my PC re-tuned with the mods below.(i have scat crank"cast", h-beam rods and keith black pistons)

 

I would say stock or no more than 6000. Your bottom end is fine, it's your pushrods and top end that worry me.

 

IT all depends on your setup.

With my 350, stock bottom end, I turn to 6600 with CM 612 springs and a 233/239 cam.. That's PUSHING it with my top end, but I don't get any valve float. I plan to switch to some comp 918 springs, and turn to 7100. Honestly, if you make power, turn it as high as your parts can handle.

 

Im looking to set the limiter around 6500 beacuse of the hotcam kit and the crank and rods and pistions are better than stock.Any objections?

 

That sounds about right. I spin mine to about 6300 all motor with the 224/230 cam and only 6000 with juice. I dont experience any valve float. The bottom ends are really the weak spot as above mentioned. Its the top end you have to worry about.

 

Take it to the track to make a decision. There are a few guys here turning more rpm then they probably should be with the cams they are running just because the engine can. In all reality, they'd probably go just as fast down the track with a lower shift point. But you never know til you iron out your on-track consistency and make some adjustments.

With the Hot cam in a 383, I'd guess on a peak of close to 6k rpm. You should try shifting a few hundred rpm on the other side of that.

And guys, if you're running a 350-ish motor.... that 383 is not going to turn near the same revs with that cam....
