Haven't hit it nor do I know what it is set at.
Only purchased the car a few weeks ago. 368ci Corey Henderson built 1991 Z. 4.10 gears. I did 3 pulls in second gear and the tach needle swept just above 8000 each time at which point I decided I better shift. Don't know if it is accurate but sure sounds like it's well north of 7000 anyway. |

Technically not stroked. It's one of Pete's 391 cubic inch closed deck blocks (larger bores) with stock crank. Add to that Pete's port work of everything and his aggressive stage 2 cams (plus of course long tubes, no cats and Corsa exhaust). Makes peak power at 6500rpm and holds it all the way to redline. Build thread here.

Was your tach off a consistent percentage throughout the range or was it only skewed at the top? |

Here is a chart you might use to see if your tach is tracking correctly...assuming your speedo is corrected for the 410 gear! And...(IIRC) there is a way to determine the RPM from the DIC (digital information center - the display in the dash). As I seem to recall, (someone please chime in here!) a number can be retrieved and a multiplier is used to ascertain the actual RPM. OR, if you have a scanner, of course you can read and compare the analog tach to the digital reading. P. Last edited by Paul Workman; 11-06-2020 at 07:43 AM. Reason: tpyo |

I checked the tach gauge vs the readout on the HVAC control. Hold up and down fan speed buttons simultaneously until 00 appears then tap up until 06. Tap the fan button. This gives you rpm/25. It won't read all the way to 7000 but I was able to verify my tach gauge reads about 15% high throughout the entire range. So 8000 is really only about 7000. Will have to get it calibrated.

I don't feel like reading the whole thread, but I'm wondering... I feel like I drive the car really hard... But I don't recall hitting the rev limiter! What happens when you hit it, RPM decreases a little bit by itself, then increases back up?
My 1993 had a steady rev limiter, RPM doesn't decrease when I hit it... |

The power doesnt drop off in a stock LT5 before redline.
Unless you go past the power peak, you will be way below it after your shift. Sent from my iPhone using ZR-1 Net Registry |
