LT1 M6 Shift Points
Im just wondering when the shift points would be on an LT1 with the following mods: (I know many of the listed mods are irrelevant)
ASP Crank Pulley
Pro 5.0 Shifter
Hotchkis Stabilizer
Hotchkis Lower Control Arms & Panhard bar
K&N Filtercharger
Airfoil
4.10 gears
160deg Thermostat
Hooker Long Tube Headers
Hooker Y Pipe w/electronic cutout
LT4 Clutch and flywheel, installed less than 2,000 miles ago!
SLP 2OTL Exhuast
PCMforless Programming(tuned for 92octane)
Carbon Fiber Drive Shaft
MSD Ignition w/ Performance Plug Wires
Crane Gold 1.6RollerRockers
Manely Valve Springs
Titainium Retainers
Eibach Pro-Kit Springs
KYB Adjustable Shocks and Struts
Reason being, i just shift when it seems to get really loud... i have only had the car for about a month, so i dont have it down yet...
The MSD box has a chip in it for 6200 RPMS, but my tach (stock) seems to go well above that before i shift. I dont know if the tach is off or something, but it doesnt seem to redline until like 7k (not that i have tried to rev it up that high)...

I would say set your shift light a 5800 rpm. That way when you actually see it and start to shift it will hit about 6000-6100 rpm. I would use your factory tach readings even though they are usually off a little bit.

m6 with a 230-236 cam shifting at 6000. get the car on a dyno, see where you make your peak hp and peak torque, **** at your peak hp and try to land in your peak tq. this has worked best for me, still want a manual valve body turbo 400 though. haha good luck

i always thought it was best to shift after peak HP, you are still making HP and it sets you up for higher RPM in the next gear. met a guy at the drag strip with a z28 that was identical to my TA as far as bolt ons. he even had the same name as me (mike smith, big rarity there). anyway, i always got him by less then a tenth , every time, by shifting a tad higher.
