What did I do today. Well, checked pushrod spec. Was barely over .040 preload, in the center portion :(

So, the new 7.425 pushrods I had ordered, got it just to the bottom of the spec. Good news, they are 90% quiet through all rpm range. Bad news, should've ordered 7.450 and they would've been perfect. I'll see how long I can tolerate the slight noise :cool:

Basically, the BTR cam I put in it isn't consistent throughout. The 4 outside corners are perfect, the middles are right at the bottom. Long story short, when buying a cheap cam, check every single one

Changed the rear shocks on thecopcar. Not hard, but contortions were required. Dunno if the consumer Hoes are that way or not but the rear sway bar ends are in the way of the lower bolts. Had to jack up the frame to unload the suspension so the bolt could clear. Tires stayed firmly on the ground.

I bet you can tolerate it pretty well from inside the cabin. You make it sound like you are running solid lifters on a high solid roller cam with a lash at like .030-.036 lash.

Cleaned/re-oiled air filter, removed that rear engine bay gasket previously mentioned (took 3 seconds/seems like it would help a little with keeping things cooler, idk), and went to town with a dremel on my center console lid.... proof of concept but I kinda dig it. Needs a new cover and some support on both sides. There’s about 1.5” of gap on each side so it rocks side to side currently. Could sew in some black fabric or vinyl to cover the top of the tank

Exactly. Getting rid of the sunroof the proper way after multiple failed attempts using other methods

guessing you'll need to do some bracing when cutting off the top?
Or just for fill panel?

what's wrong with the sunroof, just a pos?
