Valvetrain upgrade: LS6 springs, seals, trunnions

Time for a valvetrain upgrade. I’m hoping to raise the rev limit a little bit to avoid the really short trips to 4th gear on some of the local tracks. I’m also prepping for a cam.

  • LS6 springs. Super cheap compared to the .660 springs. Should allow 6500 rpm easily.
  • TSP valve seals- These are the later style seals, but I was getting a puff of smoke on high vacuum with downshifts and this was suggested to fix it. with 90k+ miles it’s probably time anyways.
  • Michigan motorsports trunnions. These will keep the needle bearings from escaping with the higher lift and rpm.
  • new gaskets, etc.

I also did a new fuel filter and donut gaskets. Just maintenance stuff.

Here’s the cam I’m planning on putting in.

I also discovered the driver’s side valve cover has been updated to a 2014 unit. There were improvements to the amount of oil the PCV system would suck up over the years.
