Ok so I just ordered a Harlan shift light from frost for only $55 bucks so now I need to know what is a good shift point for my 1998 Camaro Z28. It is a all M6 bolton car mods are as follows:
K&N FIPK
Ported TB
LS6 Intake
UD Pulley

LT Headers
ORY
Custom Flowmaster catback
Mail order tune from FROST

i shift at 6800. u will get a lot of different answers with this. 7000 is about as far as you want to go if ya feel lucky until you get stronger rod bolts lol. there are people who shift at 7000 or a little more and havent had problems, but thats really pushing it imo.

thats what i thought at first. at first, i would shift around 6500. but everyone i know runs their cars to around 6800-7000. if your car has high mileage, you might stay a little lower, but otherwise it'll handle it

Yeah I got one. Anyone who tells you to spin your stock motor to 7k is a fool. A damn fool. The stock valvetrain is barely adequate for stock rpms, let alone 7k, and the stock cam and everything else about the motor isn't designed to make power that high anyway. Also, are the so called advisers gonna buy you a new shortblock when you sling a rod or spin a bearing. Yeah right.

He has a 98...I wouldn't spin past 6500rpm period with those rod bolts.
IIRC peak rwhp for stock cam is around 5600-5800. You want to shift just a little after peak. Keep it well under 6500 for sure.
Sure someone will chime in, could also search I'm sure it's been asked before.

Please do not give advice for cammed cars to those asking about stock cars...his stock cam is nothing like your MS4 cam with upgraded pushrods and valve springs.

I don't believe so, but someone else may chime in that knows better.
As for the original question. I've got to agree with the others that have stated to keep it below 6500. Myself, with the stock valvetrain, would set the limiter to 6400, and shift points at 6100. There's no sense is risking serious damage. If you can't pay to fix it, then don't risk it. Stay safe, and enjoy the car.
Good luck.

What about them is different? Just stronger bolts, or a different design? The car I'm Gettin is an 01, I'm assuming it would have the better ones... So if I got a medium cam in the future and wants to spin it to 6600 with the proper valvetrain would the bottom end hold up fairly well? I use to spin my LT1 to about 6400 with just a little spring work and it held up great. Just curious. I've never seen the inside of an LS1 in person. I formerly was a Toyota mechanic.

01-02's have the stronger rodbolts that are not as prone to stretching causing a spun bearing. MOST of the time these are fine to 7K. FWIW I spun my old H/C/I 98 346 to 6500 for 2 1/2 years before a broken #7 ringland did that motor in...
