Yeah unfortunately I have the springs already.Originally Posted by Anthony Smith
Injectors aren't the issue it's stations and being my dd
i have two sets of 60s one new and the other used I don't have 42 it's a hard decision honestly I would love e85 but seems like that would have to wait for my xpz build

Dude if you have two pairs of 60's, throw the other in the vs build. I had 60's lying around because I was going to go turbo, but I scrapped the build. When I did my NIC build, I bought 42's, thinking 60's would give me issues. You can tune 60's on a "mild" setup like what you're doing. If anything it's a muh better injector and better spray pattern. I know people bash the guy, but Nick (snowflake) tuned 60's on his N/A 3.8 because he was going to turbo it a couple weeks later, and he needed to the the intake manifold swap to convert from S/C to N/A. He said he had no drivability issues and gas mileage was about the same.

Sorry to break in to your tread but dude I'am looking for 60 to 90 injectors for E-85 any of you want to turn them loose $ ?

Looks like most of the misinformation have been fixed in this thread.
Except, don't use L76 springs. They are not rated for the lift the VS cam on stock rockers will make.
03-22-2013
L76 springs are rated to .530 lift, they don't bind until about .580.
03-22-2013
And VS cam lift with stock rockers is somewhere around .544. Hence why they should not be run with that cam.
03-22-2013
I thought the lift on the vs was .512 on the intake side and less on the exhaust. Is there a new grind?
03-22-2013
No, that is with 1.6 ratio rockers though.
03-22-2013
If you're worried about deflection, you can run an LS9 spring, which is essentially the same as the L76, rated for .570 though.
Thyere like $2.80 each from GM.

I did not know this I thought it would be too much of a injector to use on a vs cam and mileage would drop a good amount over 42s.
In that case I think I might get two different tunes one to run on 91oct and other on e85 with the same injector if it isn't too much of a hassle.
03-22-2013
Sorry for the reason why I had them and not sold them is because I still can't decide what fuel to go with but now seems like I can use my 60s for 91oct which I didn't know
03-22-2013
I run my comp cam with 512/512 on L76 springs and stock rockers, it is perfectly fine after 20k....
As long as it is tuned properly injector sizing shouldnt have any effect on fuel mileage.
03-22-2013
I don't care about deflection.

I know people do it....it's not something I would recommend though.
Just like myself running a stock timing chain with 20k miles on it...10k using LS6 springs, and 10k using 130# springs. I wouldn't recommend that to anyone.
03-22-2013
Maybe some detail, article, or documents of some kind to illustrate your point would help people to understand why a spring that's more than capable (infact nearly ideal) of handling a vs cam shouldn't be used.
These one liners aren't helping anyone.

Read what I've already posted. Post #26.

As far as the Trans go say I do get to 350whp max out if the setup I plan.
Will a shift kit harden 4th be enough I was planning on using the sonnax upgraded valve body but idk if there is stages of this there is a guy selling it on the forums.

isnt stock 1.6?
206/216 at .050"
Intake Lift .320" (.512" lift at 1.6:1 rocker ratio)
Exhaust Lift .317" (.507" lift at 1.6:1 rocker ratio)
115 LSA
Comp Cams - VS Cam #COMP-3311/3303-115+2-VS
03-23-2013
No, you will probably want an input shaft and 7/8" chain as well.
03-23-2013
No. Stock rockers are not a fixed ratio. The higher the lift, the higher the ratio.
