So got my LS3 intake off. took the injectors off and guess what. THEY are way to short to go with the railes and mounting brakets that came with the rail kit, i kinda thought that would happen sense the rails sit so high.
So I'll be looking for the regulor hight LS2 style injects to use with the set up.
The Edelbrock rails don't have a grove for the injector retainer. So thats the way the injectors are held in place.

Second, but not that bad, the intake needs a little trimming on the outside of the intake runners. Or maybe I need to get the intake milled to?
This won't be to bad, think it because the heads on my car are milled a bit.
So all in all it not to bad
I'll try to get some pictures out later tonight or tomorrow

 

can't wait to see results. i want to do the same swap. do you have good base line track and dyno #'s?

 

FAST makes 33, 46, and 57 lb/hr LS2 injectors. I should be picking up a set of 46#ers soon I hope.

 

Dont have any dynos for the car.
have a lot of passes on it though

 

Yea I was looking for some today
But going to see what my builder has laying around, think he has some 53# setting around. might have to get conectors harness

 

I thought it was supposed to work with the shorter injectors, got this from Edelbrock website:

Aluminum Fuel Rails
CNC machined from aluminum extrusions, these fuel rails have a 9/16" i.d. fuel passage, a flow-through design and 3/8" pipe threads on both ends. All hardware is included. Bracket stands included match with standard injectors (2.650" O-ring spacing) or pico injectors (1.50" O-ring spacing) as indicated.

 

et and mph is better than the dyno.

 

the o-ring fit, but there injectors are shore not the LS3 ones

 

yea i agree. Ill have it on by next wendsday hopefully.

 

You may find that the taller injectors require a different (thicker) o-ring. I run Ford Green Tops (42lbs) and had to run the Katech o-rings with the FAST fuel rails..

 

thanks, Ill be dropping the car intake off tomorrow for a little work in the intake runners, doing a little clean up.
going to go with some 52-53# injector my engine builder has at his shop.

 

any up dates? pics?

 

no pictures yet got it running toight but did not drive because its wet out side
the car sounds awesome. but I will have to get a Custom Hood!!!!!!!!
none of my custom elbows would fit under the stock 05 hood. so i decided go with the one that will flow the best(the biggest one) so
ill be doing some tunning this weekend but want be back to the track for a week or two till the hood get done

 

i hope you get good reults. do you have a feelin the L76 is holding you back or you just trying to get more power?

 

I think it is, the most iv seen a LS3 intake flow is 330-340 cfm, the ported Ls3 head can flow into the 370-380's. Plus the Victor Jr work all the way up to 7500 the LS3 fall off around 6500-6800 depending on work to it.

 

i wonder if your going to lose a bunch of torque? that's what the gm single plane did.

Think it want loss to much dude to have 4 long runners still, plus on dyno test the intake still did well down low on tq
