I have a 1986 z28 with a 305 and a Q-jet which according to most people does the 1/4 mile in mid 17's. Right now its totally basic so heres the question you probably hear alot.

Should I stick with the 305 and if I do whats the first best thing I should do? My second option would be to drop all the emissions crap most likely and stick something such as a 350 in there so I can have a clean start. So as clearly as possible which do you think I should do?

LOLOLOLOLOLx1million.
A mid-17sec timeslip.. I think not. More like low 15's.
Look at my sig.. add $800 to your 305.. read my sig again and compare your car.. then look at where 800 dollars would get you w/ a 350.. MAYBE the whole engine. But that would be a STOCK engine that my 305 is gonna rape. Do your research, spend $800 and get 300hp and 350lbs, and then rape some 350's.

Edit: The only car that i can think of off the top of my head is pre '95 honda's and the like; NO Camaro EVER did 17's.

I said that a stock 305 in a third gen will be doing abut mid 17's, thats complete stock.

Like I said in my first post; 15's ARE THE SLOWEST THEY ARE GONNA GO. If you can drive it, mid-lower 15's. I have a 305.. I would know.
Not being a dick, trust me (as I know it is impossible to interprete emotions on the internet)

I was just disagreeing because I have been looking at sites and three of them all said the same thing, about mid 17's and with a grand they are running 13's. At the end of theese articles they say they should have started with a 350 because af so much work it would have payed off to have a 350.

Well, I dont know where you were looking, or how serious the people saying that were, but TRUST me.. 15's for a 305. There is no way in FOCK taht they would run 17's (lol)
And like I said.. I have a 305, I am spending 800 dollars, and I am going to get an ammount of power that will put LT1's to shame, as well as most of the lesser-powered LS1's.

Now dont get my wrong, I LOVE CHP.. but they are full of **** sh*t sometimes. They are very unrealistic sometimes. And this is one of those times.

Yossarian14

Alright thats possible, I'd rather take your word anyways. Whats the first thing I should do to increase power?

Do you know anything about engines and how they work? (Not being a dick.. just trying to teach you something if you dont already know it )
To sweeten it up, an engine sucks in air, burns it, and expells it. Now, the first thing to do with ANY car you want to soupe-up, is make that happen more fast and more efficient. The thing is though, with our LG4 we ESPECIALLY want to take care of this. LOTS of air in FAST, burn LOTS of air, and LOTS of air OUT fast (even moreso on our car because they are horrible with flow stock)
Our LG4's have HORRIBLE.. let me spell that.. H-O-R-R-I-B-L-E intake and exhuast manifolds. They are restrictive as FUC K, and they are just overall junk.
That help you any?

Just wanted to add my two cents.

I have a stock 84 with the 305. I have never had it one the track but I am certain that I can do the 1/4 mile somewhere in the the mid to low 15. I know how it runs on the street and am dying to get it to the track for a test run. Hopefully this spring.

Yes I know exactly how an engine and all other components work but I understand why you asked. The rule I always hear though is that there is no replacement for displacement, you hear in magazines, tv, etc. I just wondered if your going to put that much money into an engine if I should put the money into something which most people say is more capable in the long run.

Your talking of topping out at something at 13 unless you get drastic. I always see people with 350's or 383's getting into 11's so I'm just trying to figure out if they are a better investment.

85_305

There are plenty of people w/ 305's that hit 11's. In fact, I believe a member or 2 here has done it. A 305 is 350, only they have a different bore. Pretty much the same thing.. put $800, or even 1g into a 305.. (and that includes the rebuild!) and you will be in 350 territory. (A very FAST 350 mind you.) That is very true that for the most part, there IS NO replacement for displacement, but that is refering more to the 1.0 liter cars, versus a 5.0 liter car. THEN it holds true. But for a 305 and 350.. really no difference. I will be going 13's in my car by this summer, and I have done nothing drastic at all.

What happen to that heat sensor thing if you install a dual snorkel? Does only one side work or?

Go 350. I swapped my wifes 2.8 for a carbed 95 LT-1. For the prices we paid and all the swapping we did, we have around $1,000 in a 12 second ride, counting the engine, trans, car. Not counting Iroc Rims

Just a few pics. We're pretty proud since it's the "company" car
