LS1/LT1 lifter springs?

[geldartb]

ok so ive had the LT1 lifter springs inside my lifters for awhile now and all seems good.

way back in June i came across a set of LS1 lifters uber cheap on ebay so i grabbed them.
finally got around to taking one apart last night and did some measuring on the springs.
the LS1 main spring is around 1mm bigger than the LT1 main spring. the check ball springs appear to be the same size.

overall height of the two springs appears to be the same or within a hair's distance.

now would it be worth it for me to pull my lifters while i have the engine apart sometime in the near future to seal the valley's better, and swap out the LT1 springs for the LS1 springs.

For 1 mm difference, no. I have a hard time believing it would make a big difference in spring rate.

If it's apart, why not?

[geldartb]

well its not apart yet but will be when i get the motivation.

how would you test how much force it takes to compress a spring this size. anyone have the gear to do it.

Put bricks on on top of each and take note of the weight of bricks, and measure the height drop. lol


Honestly, take it to a machine shop that messes with off-road RC hobbies. Or do like I first suggested.

not worth it, leave yours alone

yeah thats what i was figuring while i was looking at them the other day.

that will save some time then. all i have to do then is take the lim off and re-rtv it and put it back together.

Haven't even seen anything conclusive yet about the benefit of LT1 springs vs stock, so I wouldn't bother swapping from LT1 to LS1 since you've been running them with no problem so far.
