3500 valve springs.

[MidnightriderZ24]

ive got a set of used 3500 valve springs that came out of a 18,xxx mile 3500. comparable to ls1 springs. 60 shipped

[MidnightriderZ24]

bump!

[95Grand-Am]

What year 3500 did they come off from? Do you kwow if they will fit 3400 heads And are they any different than 3400 valve springs? I'm looking to freshen up my heads and these have alot less miles on them. They are clean with no surface rust?

[MidnightriderZ24]

theyre from an 06 g6. yes they will fit 3400 heads. they have more closed and open seat pressure. theyre spotless, im goin over to my garage today, ill snap pictures and post.

[95Grand-Am]

Do you Know how much more seat pressure?

[MidnightriderZ24]

open seat pressure is 235lbs, closed is 77lbs. 3400 is 225 open 75 closed. good for a little more pressure and a freshen up.

Will these fit a 2.8/3.1 mpfi using stock MPFI retainers, seals, seats etc etc? If not, do you have all the other parts to go along with it?

[MidnightriderZ24]

i have the valves and everything else, but i will be using them. from what i remember they do fit gen 2 stuff, ill double check.

[MidnightriderZ24]

after searchin the forum a little you can use the stock retainers and locks. and they will fit over the stock seals and seats

[SappySE107]

They are basically the same as stock 3400 springs. Age can give you those kinds of differences in pressure.

[1988GTU]

So I can reuse my old parts just swap out the springs?

Those springs have got to be better than what this engine currently has.


Let me ponder about it for a while, don't hold them for me. If you have a buyer, sell them!

[MidnightriderZ24]

cool, im pretty sure theyre goin nowhere though.

[95Grand-Am]

Do you want to sell the valves and spring as a package? I'll be really interested if you do.

[1988GTU]

I am going to have to pass, unless you want to sell them for 20.00 shipped?
