Who's spun their LT1/LT4 the highest on an OPTI
Here's 6972 on an OEM OPTI..

Whos had their OPTI higher....and had the OPTI survive....mines been to 7005 (fuel cut off) at times but I don't have that logged.

Just a little 355...pulling D right before shifting into OD.......

7000 just a couple times but 6700 a few times a week. I've only had my opti's go out because of leaking water pumps... never from RPMs.

 

I've had mine as high as the PCM will let it. It's a OEM unit I got from Dal at VanDevere's before he left. Holding strong.

How high is that? Are you still on stock tune?

Way back when I had my LT1 , it was ran to 7000 routinely . I was one of the lucky ones to not have opti problems at all . This was back when the OEM opti was only thing u could get .

 

7000ish?

From what ive read most people have troubles with the stock pcm revving much past 7k. My TA saw 7k a few times on the stock 110k opti and 6800 regularlly. The only reason it ever saw 7 was because the tranny decided it didn't like shifting into 3rd anymore as it was also the stock 110k 4l60e.

 

as high as the stock pcm will let it...me and many others have done it, stock bottom end cam only
