Man that sounds good! Congrats and glad everything is going well.

 

Real stupid question. When I go to tighten down my rockers and I'm on tdc should my spring be compressing just a little bit or nothing at all?

 

As long as you're on TDC compression stroke, not exhaust stroke, no the valve should not compress

 

ok figured as much due to the fact of compression, just making sure cuz. Just went out and checked again with a feeler gauge again on a couple more and one was even .025 and another was about .015 feel like 7.375 will be the best bet. Thanks again for all he help.

 

Well, checked 2 more cylinders and ended up with same results, sorry lil OCD with this stuff, just wanna make sure its right.

 

Didn't I read you are using Morel 5315? Those are Hydraulic.
What are you using a feeler gauge on?

 

Just kind of a check to back up the readings I have. Obviously current push rods are too small. Check with feeler gauge between rocker and valve to back up my zero lash and so far it's dead on what I've been reading on with the comp checker. Darth v8er's idea and he explained it a few comments up.

 

To determine how much lash there is which can in theory be used to figure the correct preload as a backup verification so to speak. OP is using a 7.3 pushrod and netting .015-.025 lash. So in theory he needs a 7.375 pushrod to get .040-.050 of lifter preload.

 

No such thing as too OCD with valve train geometry. Getting it right is worth power and RPM.

 

That is true. Just hoping that I didn't hurt anything while driving.

 

Nah, you didn't hurt anything. At worst, you might have scuffed up the ends of the pushrods you're replacing anyway. As to the opening valves with the checkers, yes I did, but I check length with a caliper, not the thread and rotation counting method. It's the absolute best way to do it.

 

Sweet. Yea I will have to do that next time for sure. Feel confident with what I got now. Just glad everything was pretty close. Still think it's crazy adding as much as I did lol. I mean .075 is more preload than 5315 calls for. Can't wait till they get in and fire it up

 

You are not going to be at .075 preload, you will be in the .040-.050 range if you had .015-.025 lash with a 7.3 pushrod. A 7.4 push rod would be in the .075 range.

 

o for sure I'm just saying, It's bad that it was off so much that I added more preload than the 5315 Calls for. Meaning I wasn't even at zero lash. If that makes sense lol. I know i won't be at .075 pre load. Idk how to say what I'm saying while typing lol

 

I know what you mean...No biggie.

 

Well first start up with new push rods. She had no idea what to do. Can actually hear the cam now for dang sure. valve train is so quiet, have a small tick on driver side but i do have a small exhaust leak at the collector so that could be it. Either way I'm just glad its where it should be now, thanks again for everyones help.

 

sounds great!

 

Thanks!

 

Hell yea! Sounds good and kind of similar! lol

Glad it is working out for you, i'm assuming now you can hear more of the sewing machine effect from the motor versus the tapping of the pushrods?

What kind of catback you running?

 

Thanks! It's actually extremely silent. I wanna say quieter than it ever has been. No sewing machine noise especially compared to my buddy's old ls2. It's 3" duals with x pipe over axle with magnaflow bullets.
