well i have a Lt1 and i am going to install a single plane intake now as for the vacuum lines that ran in to the stock intake can i just delete all of them or most of them or do i have to keep them i would like to keep them but if they have to go that's cool where i live we dint have the emissions test so it dont matter

AFAIK, you can delete everything except for the vacuum line to the fpr and the brake booster. You may even be able to delete those.

well i am new to the high performance thing here is what i have
96 impala SS
Lt1 5.7
stroked to a 385
Afr heads 210
and a single plane intake with 90mm fast
i bought the intake used from some guy but he isn't emailing me back so i have to figure this out also as for the headers i am going to get new ones soon just still looking for the right ones
and for the PVC if i can trash it that's cool i dint care

You need a PCV system. At least put two breathers in the valve covers.

Need a vacuum for the Opti, brake booster and FPR.

Looking at your setup where are you running your reg? Looks like fuel is in series and you terminate at the rail so....

Yeah, I would just run two passenger side valve covers and put screw in breathers in the oil filler neck holes.

I don't think you NEED a vacuum for the distributor. AFAIK the vented opti's were introduced to help vent the ozone created in the cap, it also helps to keep moisture from settling in there, but It's not absolutely necessary. Look at '93-'94 optis, there is no vacuum.

so what do you mean about the fuel the fpr i was ust going to put at the end of the line where it is going in if there is a better settup please tell me

Yeah, if you put it in between of the rail inlet and the feed line, you should be good.

rajun_cajun

it isnt that bad of a lt1
what yall think

Where your rail is plugged you can put a FPR and return, that's the way the stock F-bodies are run. As said above you can also put it in the feed line.

I didn't see anything about a cam, but the rest of the setup looks like it will run nice. Personally if you can, run a 4-hole, they are a lot better than an elbow/TB setup. You can get a carb hat and tubing for you CAI.

No.

You need the regulator to regulate exactly what pressure is in the line ie: at the injectors.
You'd put the regulator just after the line exits the second fuel rail.

I agree.

joelster

There is no return line on that setup you have there.

rajun_cajun

does anyone have a pic so i can understand it thanks

rajun_cajun

my fpr has three outlets in it one that fits the rail and two more i was guessing the other two was supply and return
