LT4 - Rev Limiter
At the track I have to shift into 3rd at the 1/8th just prior to the finish and into 4th at the 1/4 just prior to the finish.
I would like to try raising the rev limiter to get through that last 100 feet.
Anybody else done this?
Do you think 6700 would be OK?

Re: LT4 - Rev Limiter (rcolling)
You may want to change your valve springs before spinning your LT4 to 6700 rpms. Jim "96GS#007" Mason is running his LT4 to 6800 rpms, with upgraded valve springs. Maybe he will chime in on this thread.

6700 will be fine. Keep a close eye on your valve springs and consider them a "wear item" if you race a lot.
I just switched to Crane p/n 99845 H-11 Tool Steel Springs. I trashed a set of springs from Combination Motorsports in less than 6 months doing driving schools, open track sessions and auto-x's.

What did you have to do to make those springs work? I assume they are not a drop in replacement.
