Gearing questions 7.5 rear

[Stupidquestionspro]

The video shows the flash at 2700ish, you say your speedo is right on, if so the Speed/RPM reflected in the video is correct for 2:41 gearing and tire size per the RPM calculator i posted earlier.
This run sounds better after the throttle cable replaced compared to the first one. Still make sure the blades open fully when pedal is to the floor

It is right on max 1-2mph off and that’s interesting because it would almost mean that it has to be coming out of 3rd gear somehow or the tach gets progressively more off throughout its range and thanks I thought so too I’ll have to get someone to press the gas for me while I check the throttle blades.

Also what do you mean flashes I don’t understand.

sorry I did not put in the "TC" I corrected it.

Here is a good explanation of TC stall and TC flash

What is Torque Converter Stall - Hughes Performance

Torque converter stall speed is the maximum amount of engine RPM that can be achieved in an automatic transmission-equipped vehicle while the transmission is in a forward operating range without generating any driveshaft motion. All
