    Need ideas for 90k miles check-up

    Hey gang,
    I'm coming up on 90,000 miles on my 99 Trans Am and am doing lots of maintenance stuff while I've got the $$ to do it. I'm already swapping the break rotors, break pads and clutch. Any suggestions you all have on things to check or replace that routinely cause problems would be most appreciated!

    Mod List FYI: Fast Toys ram air, SLP 85mm MAF, LS6 intake manifold, underdrive pulley, Corsa cat backs, SLP torque arm, SLP SFCs, Firehawk wheels, short throw shifter, a few others not as important

    Remove motor.
    Install stroker.

    Sounds like you have what you need.
    Might as well get the basics as well.
    Coolant, oil, etc.

    How about the timing chain? When do those usually need replacing?

    If you are there, it wouldn't be a bad idea.
    If you do that, upgrade your oil pump as well.
