i just colapsed a stock lifter. i am going to order a complete set from some where to with stand my cam, 216-220 56x-56x 116+4 i havn't really looked at them yet. just seeing what works best for people

 

Not too many options for lifters out there, if any. I did just read an ad for an updated LSx solid lifter design but nothing for hydraulic.

 

Talk to thunder racing.
I ordered a set from them.,
I think I have the same problem you do

 

You guys are runnng Comp grinds, right?

 

ok... I knew I was forgetting something...

Lifters. And rockers....

What are the limits on the stock stuff? I'll be pushing big boost on a 408 with a 230/236 600 lift 114lsa cam...

 

I also have one that is bad. Just havent felt like pulling the head to change them. From what I have read, the stock GM lifters are as good as they get. :dunno:

BTW... which lifter/s let go on you guys? Mine is either in #5 or #7. Oh and I am running a FMS (cammotion) grind.

 

i ended up having two weak lifters i dont rem which ones they were. i went with stock lifters, had to drive 2 hours one way to find head gaskets though

 

Is collapsing lifters a result of cam/spring swaps? Is the extra tension too much for the lifter? I'm getting a little paranoid with all of the ticky and tappy noises I seem to hear from my engine. Is this a common thing (the lifters, not the paranoia...I know that's common )?

 

depends on spring pressure. but if its a really big number it coulc be pushing it. the oil gets out of my lifters on my big block if it sits for a week or so, but thats because i am running 428 in/lbs springs

 

So with the cam and springs in my sig, would you say that I'm more paranoid than anything else?

Sorry if I hijacked this thread.
