Stock, LS1, LS6 spring info

well i wanted the titanium to shave some weight, but didnt work out like that. im just going to use the stock retainers and hardened steel locks, and i think ill keep my lift at a little below 500 just to be safe

Good idea.. You can always up the duration to make up for the lower lift as well...

[gectek]

well i think ill go with the 507 as max lift on ext. but anyway Ben do u have a diff number for the titanium retainers that u use on the beehive springs?

[SappySE107]

A different number?

[gectek]

yah u asked me the # of the retainers u used that didnt fit and they were 788-12 for the beehive springs and was just wondering if you had a diff # for them. i took mine back, but i really want the titanium retainers and i get a big discount from comp, so i was still looking for some.

[SappySE107]

772 or 774, one is titanium and one is steel.

[gectek]

cool, the 772 is the tit retainer. also what locks were u using for those, the hardened steel or stock, because the stock 3400 locks are about 2 or 3 grams lighter for the pair than the hardened steel from comp

Ok, i don't get it...

LS1
1.7" 106#
1.3" 177#
Coil Bind 1.290

that means safe lift is .410 with those springs.. when stock 3400 lift is .430.

Has anyone ran higher lift on the LS1 springs?

2.8 & 3.4 Crate Spring Rates ???

Hi , mayby a bit off topic but was curious if anyone knows what a stock 88 2.8 HO spring is rated at , and the same for the GM 3.4 Crate engine spring, My cam will only have a max lift of .456 inch so would the 3.4 crate springs be a good choice ? Thanks Bill..

should all be in there

The pressure and coil bind numbers aren't right. I wish this thread would die honestly. Those measurements were for what scott at the machine shop here felt was a good max lift. They are not true coil bind. .53x has been used on the LS6 springs, though I prefer to see .52x max personally and use the comp 26986 springs for higher lift or machine the heads to increase the install height to 1.75"

So in that case, what's the real specs on the LS1's then?

we're looking at running around .470 lift. Install height is 1.682.

[gectek]

why such low lift....stock 3400 is 436

[SappySE107]

I thought I posted in another thread on their specs. They aren't much better than stock but I don't know how much lift you can go. After seeing them coilbind on a stock 2.2 with the 2.2 retainers, I don't trust them for much over .430 in our motors.

[gectek]

but ull trust the LS6 til about .520 or so right
