What decides safe redline?
What decides your safe redline without leaving anything on the table.
If you have a forged 347, ARP bolts and the GM hi perf lifters from SDPC and a 232/240 cam where is the redline? If the lifters arent an issue whats the weak link now. (Besides the cam and where it falls off)
Just the rockers? Should you be stepping up to guide plates and such or is having Harland Sharp through Nasty just as good?
At a point where it doesnt make sense to leave something to chance.

... sounds about right. After mine was forged and built, I've rev'd to 7,000 rpm's several times and the engine hasn't sustained any noticeable damage. With that cam and motor you describe, my personal opinion is that your shift points should generally be no higher than 6,800 rpm's, but, ideally between 6,100 - 6,350 ... just my opinion ... a lot of other smarter folks here will prob differ in opinion.

Well the folks at TR said I should be shifting the 224 I had at 6400 rpms. We figured a shift point at around 6800 when they spec'ed out the cam for my weight and gearing. Safe redline with comp replacements was around 7100-7300 he figured but with the new hi perf lifters that should increase. Of course it doesnt make sense of the power falls off the table but its good to know where your limits are.

If you look at my dyno graph in my sig, my 224 cam was still pulling at 6600 where the rev limiter is set. And it's only set there because I have close PTV clearance issues. If the clearance was there, I'd have it set at 6800 at least. Plenty of guys spin a stock LS1 to 7k.

If you want to get a really high revving motor call Katech
Good enough for me.
