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.

I'm gonna take it back apart and check each one. Put the appropriate rod length and fix it. It's the little things that bother us sometimes :manos:

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.
The end links are always in the way of the shock bolts unless you change their location by jacking.

Spent another hour or so today modifying the Harbor Freight Ball Joint Separator and got it to within a 32nd of an inch when I decided to just cut the bottom of the ball joint studs off with a dremel. Then the tool fit and I started manually cranking it with a ratchet. Stopped for a moment, looked over at my daughter and BAM! It broke free and scared me senseless! Same thing happened on the other side but to my daughter this time! BAM! LOL

She changed the engine oil cooler lines and then went off to her volleyball tournament and won all the games with her team. Proud papa. Checked over the knuckles on my work bench and fiddled around in the garage and put everything away for the night.

Hoping to accomplish more on Sunday, have to pick up the bumper on Monday.

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

Trying to decide if I'm motivated enough today to install the new ac parts.

Summit sent me a drier that had the factory seal/box opened, so I'm just checking the vacuum for now...

View attachment 278167

Summit: I'm not happy with open box ac parts, especially the fkn drier!

I'd send that ****** back. I put one on a camaro that had been opened. About 45min into the drive, it froze, blew pressure release that sounded similar to a ******* bomb, the blew its load all over the engine bay and windshield. I'll never use a drier that's questionable again
