I'm in the middle of taking my lt1 apart and when i took my injectors out the number on them is W 52 is that the stock injector. Because i plan on building the motor and one of the things i'm going to do is put bigger injectors so i need to know what size these are.

 

93=22lbs 94 and up 24lbs stock

make a sig and it is easier to help you.

 

i'm thinking of going with the gm 847 cam with 1.6 rr and getting heads ported and polished with a 2500 stall and new injectors and new tb thinking of 52 and 30lb inj what do yall think or suggest any info needed as i am new to the fuel injection

 

You're gonna want a bigger stall.

 

what size stall do you suggest this is also a daily driver

 

Don't go no less than a 3200.

 

More stall, less cam, 52mm TB is OK if you are reboreing a stocker, if buying aftermarket go straight to a 58.



"ported and polished" is almost meaningless as it is actually possible to make heads work worse, or in skilled hands they can be made capable of 9s NA, choose carefully. Though if you really thought a 847 was a reasonable choice then your selection skills need some work. I would say slow down and get a better handle on what is a good idea and what is not. Keeping in mind that just because herds of sheeple claim something is great does not make it so.

 

well what do yall suggest? i'm looking to run 7.80 to 8.0 in the 1/8 if this was an old 350 with carb i would have no prob this is my first fuel inj build so i can use all the help i can get

 

Well I have managed 7.5 in the 1/8th with my whale, 150 miles from home with less cam.

www.advancedinduction.com 190cc heads and cam package is responsible for the power. 3400 stall 3.73s 2.5" dual exhaust 1/5/8" midlenght headers.

Crap like the Hypertech in your sig has to go too. The aftermarket sells a LOT of junk like the Hypercrap, Granatelli etc, pretty much anything that is trying to trick the computer is bad. Really many parts that say "50 state legal" are bad, not because emissions and performance can not get along, just that by the time companies spend the coin to get through beaurocratic red tape there is little money left for meaningful R&D. The Edelbrock TB is probably the only part from them vaguely worthwhile. Injection responds wonderfully to modification, just to do it sucessfully you need to be a bit more skeptical than most. A lot of "good" companies sell garbage and make it sound good through marketing.

 

Hell, my 847 with 3600 stall and 3.42 gear is awesome on the street. Drive it everyday without problems.

What are the rough specs on your cam?

 

Mid 220s intake, low 230s exhaust under .570 lift both with 1.6s and I take just about to 6500rpms.

Lots of guys are happy with stuff just because they don't know any better, I have been guilty of it myself.

The past 2 years mine has been together I have put about 8K miles a year on it, wife even likes to drive it, it is pretty mellow for the ETs it puts down.

 

As to the original question, there should be more part #'s on the injectors. The stock 94-97 injector part # is 17124248.
