So after talking to BTR and doing some more research on the morels. It looks like their recommended preload is .035-.060
I'm at 7.330 fully collapsed. if i do a 7.275 pushrod that puts me at .055 preload. So that's what i'm going to.

I've never done this on an LS before. and guys that give people a hard time usually pay shops to do their work lol.
I won't lie, when i thought this was the clutch i legit considered how much it would be to have a shop pull it and redo it... but then i was like... This is my project car. and i've turned every nut and bolt on this thing... No reason to change that now.
new pushrods are on the way. Should be here tomorrow. Then hopefully i can wrap this thing up and get it ready for the tune! Not gonna lie... once i found out this was a pushrod length issue and not a clutch issue my stress level dropped DRAMATICALLY lol. I really didn't want to pull that trans again haha.

There are those days you want to jump out a window, but once you solve the issue - all is good!

Thanks guys,
Ya i try and be honest with my mistakes. Nothing drives me more crazy than when people defend something because it's what they have lol.
Also, found out the heads are off an 06 CTSV. so they're off an LS2. so they don't have the sodium filled valves. no big deal. Still an upgrade from stock ls1 heads
New pushrods are out for delivery. so i'll toss those in today and hopefully have a fully running/functioning car!!!! now i just have to get the stupid clutch inspection plate back in haha... sigh... that's gonna suck (have to pull mid pipe and hang the headers lower to get it in...
I'm so tempted to cut it in half so i can get it in without pulling them lol.

I think these heads are going to have to come off.
7.300 has lash 7.350 pushes on the spring.
I'm thinking that something is up with the lifters either i messed them up with the 7.4s or theyre just stuck.
Sigh.

No not yet. This whole time I thought I was chasing pushrod length issues. Intake is probably the next step and then heads. I know if there's an issue it doesn't take long to fubar the cam. But I don't think I hurt it yet. I do think I may have messed up the lifters. Or they were always messed up. Hqrd to say... i may run down and pull the intake now lol

The youtube video feom Scruff’s Garage shows how to make a solid lifter and how to measure for zero lash woth your tool on base circle. Then based on what the lifter manufactures recommendations for preload you add that length to the checker length and get your pushrod length if I remember correctly
