i am worried....i have a 86 305 4bbl an dont have the $ to buy a 350 right yet....am i gonna get shamed by alot of racers...the only mod i have yet is flowmaster duals....an soon to be gettin the transgo shift kit...

Make sure its tuned up as good as possible, run an open element air cleaner and play with your timing (mine is 8degrees, supposed to be 0), and you should run somewhere in the 15's depending on what gears you have. Your first mod should be 3.73's if you have tall gears in their new.

open air element?...lol i'm confused...could u maybe point me to the right direction....i am already plannin on getting the gears...what other mods can i do that arent so costly but have a good HP output??

You need to run in the 14's to start relaxing about the more mild N/A imports.

jocww

open element bad idea get a dual snorkel l69 option otherwise your just breathing in hot air rejet your carb new plugs wires rotor change all your fluids lose some fat in the car good tires and pray

I've never seen a dual snorkel air cleaner around here and don't have the time to make my own so I run an open element. I believe somebody was telling me they tested both and they ran the same 1/4 mile time with each. Don't know if thats true. There are only V6 thirdgens in the junkyards around here so its hard to find these things.

Most of the faster imports around here are turbo'd. Even then most of them run 14's. The really high end ones run 12's and blow up all the time. lol

what if i got 3.73s an a 2500 torque converter?....i already have an open air element an duals..an remember....its a 305..lol...i dont want to spend too much money b/c im gonna get a 350ci once i get the money but want it to be quicker an take down some of the so called "import" kids wit cold-air intakes an fartcans....lol...i'm sucha hypocrit....i used to own a souped up integra....o well...i've turned...lol...but tell me wat ya'll think

Must be a Canada thing.

hows he going to run a 15? I would guess he has a lg4 with 2.77 or 2.73 gears. these always run low 16's at union grove (AKA great lakes) drag way

305LG4Cutlass

Most of them I've seen around here have 3.23's.

PneumaticTire

Edelbrock headers (don't know the model cause they were on the car when i bought it, but are rather new) and 2.5 exhaust along with no cat and new edelbrock perfromer intake, and a new CCquadrajet and no Air pump, or Egr and a fresh tuneup has made my LG4 pretty damn respectable. I bet it would run high high 14's low 15's at the track. Maybe wishful thinking, but I know it surprises alot of people that ride in it, and it easily smokes em even from a stop without power braking. Not sure of the rear end in it however. I am currently hunting down a dual snorkel air cleaner myself to rid my camaro of the stock single snorkel.

305LG4Cutlass

I have one friend with an 86 Berlinetta with an LG4 and 3.08's and another that has an 85 Base Camaro with an LG4 and 3.08's and I've seen a few 84 Z28's with LG4 auto with 3.23's.

about2break1128

most kids around where i live dont usually mod their imports...they usually lower it, put a muffler on it...or MAYBE a cold-air intake....but hopefully after a few simple mods i should be able to compete with my lil LG4

my3rdgen

My T/A had an LG-4 with 2:73's. It was slow. When I went to a 3:73 gear it was almost too much gear for the lil LG-4. But it sure was fun!

If you go to a 3:73posi, headers, hi flow exhaust, and a new cam such as the 95-97 LT-1 (do youself a favor and get new valve springs too), IMO you will not need anything but the stock converter but that is just my opinion, spend that money on the cam. Even with the stock LG-4, when I installed the 3:73 it was easy to roast the tires.

that combination would be much happier with a roughly 2800rpm stall converter.

Nate86

I doubt you will be anywhere in the 14s without a better cam. More likely mid/high 15s.

The Performer is supposed to be a factory replacement, IIRC.

My mis-matched drivetrain time is in the sig. The L69 air cleaner is hard to find, so the open element is better than stock. If I had 3.73 gears my 1/4 mile would probably drop almost a second, because right now my 2.73s keep me out of my cam range. I'm in first gear for like 4 seconds.

Ok the time isn't in my sig, oops. I ran a 16.45 at 85mph.

The single snorkel with ducting to get it cold air would be much better then an open element. Really, a single snorkel isn’t that restrictive in the HP range we’re talking about. If you were talking about a 500hp monster, then maybe, but not something that runs 16’s. For that matter, an LG4 can be made to run in the 13’s/14’s without that much work, of course, very few people try to do it.

anymethod

L69 dual snorkel would be the optimal choice, but they are hard to find. Open element gets more air than the single, whether its hot air or not.

Fine, don’t listen… take your open element and the single snorkel with some ducting and a comparable filter to the track and make some passes with it tuned the same. It WILL run faster with the single snorkel then the open element unless you’ve got a really cool day and making a lot more hp then I’m sure you are.

anymethod

I definitely see where you are coming from. I was just talking about stock for stock, not with ducting. I am in the process of ducting an L69 air cleaner into the foglight openings for a ram air kinda induction. I have to fab up some mesh or screen to cover them though, to block rocks and sand and such. Luckily I bought the car with both foglights broken and one missing, so rather than buy new ones i'm going to use the openings for induction. How exactly do you recommend ducting the single snorkel? Closer to the ground like a cold air one?

Duct it as high as possible, the further from the road surface the cooler the air.

I would just run the stock style scoop, that screws to the holes in the rad support behind the headlights and sucks air through the hood gap/headlight pocket on the camaro… you’d be surprised how much cool air flow you get there.

ok...how would you go about ducting my single snorkel?....maybe some pics an description...thanx

83 Crossfire TA

iTrader: (2)

did I miss something?

about2break1128

lol....sorry for the stupid Q....i'm new. would you have to buy extra ducting to stretch it down to the grille? also, when i bought my camaro the guy who previously owned it put an edelbrock filter cover on top but it doesnt overlap the snorkel base. will this defeat the purpose of putting the cold air snorkel together because its already sucking air from the gaps between the metal top an the snorkel base? or if i do the cold air mod, should i look for a bigger cover for the top?

305LG4Cutlass

Yes that will defeat the purpose, that is basically turning it into an open element.

Tomorrow night I am going to the track for the last time of the year and I'm going to try the regular single snorkel with some cold air ducting vs. open element. I always thought it felt stronger with the open element but its hard to tell by seat of the pants. Tomorrow night will hopefully clear things up for me.

Post results… I suspect that with the ducted setup you’ll have to run a little more fuel and a little more timing to actually take full advantage of it. AAMOF, like I said, if it’s really cold it will be difficult to document the difference
