305 build up i know you guys say that 350s are 10x better than the 305 and i agree totally, but im 17 making **** money and im just looking for some more streetable power and fun. im not looking to beat corvettes, just hondas and the like.
its a 1983 chevy camaro 305 4bbl. what do you guys recommend? or have done in the past
i know full exhaust but what else? the edelbrock power package sounds good for 600 bucks has anyone used that before?
thanks

honestly dude, for that 600 bucks you're gonna spend for the performance package, you could probably pick up a 350 from the junk yard built. where are you located? there's a dude here in yuma that picked up his 350 for his monte for 500 bucks. shop around. see what you can find.
everyone is gonna tell you to ditch the 305 bla bla bla.. i had a 305 in my 91. i don't know what your emission laws are there, but i was running shortie headers, back to a 3" flowmaster with no cat. used synthetic oil. and used msd wires with bosch +2 plugs. msd cap and rotor. it ran very well. i had no problems. getting rid of that cat is the best thing you can do for cheap performance.

Honestly why make the car Chug more gas? Your 17 and gas is going to kill you with a gear and a cam.

save for LSx conversion 
hell even a 5.3 LSx from a truck with a 02 zo6 cam will do some damage
they go for like 400-600$ with accs. nowadays at salvage yards
and it bolts to 700r4 with some modification
keep the carb.

OK i've got a 82 Z/28 (along with a Firehawk) Anyway, normally I don't post but thought I would put my input on it since my 82 has a 305 that runs ok for a 305.
Here are the specs -
cam - 224 at 50 lift (intake and ehaust) .465 in lift 114 degrees lobe separation
Intake - Edelbrock performer
Carb - Holley 750cfm vaccuum secondary
rear end - 3.73 w/ posi
Trans- TH350 w/shift kit
It is a bit overcammed and overcarbed , Low end suffers under 3000.- if it had a stall converter it would run stronger - but it pulls nice from 3000 - 5500.
you should be able to get the cam kit for around 150( I bought mine on ebay it way just a basic kit came with everything you need, It was a melling, or elgin cam something like that)
Edelbrock intake - should be able to get one for around 40 dollars on ebay
holley carb - maybe 100 used
Oh yeah I removed all the emmissions and put on a Old style HEI (non Computer)
HEi ignition - used 10 dollars
So than brings total to around 300 dollars, you may be able to find things a bit cheaper, if you shop around. The 305 will not be the fastest thing around but will wake up enough to have a little bit of fun with. Plus if you get all the parts you can have them all intalled in an afternoon.

Carb Intake Cam. That way you can go a bigger inch motor later. Or you could grab a 350 crank and stroke it up then the heads intake carb and cam. That is what I would do if I were on a tight budget. But the thing is that the 350 or even a 400 motor would be the best investment that you can make. No one wants a 305, it doesn't move enough air...

start looking around at local junkyards, from my past experiances the 305 isn't a complete waste of time, but if you can get a 350 for a few bucks at a junkyard then go for it
a guy i work with has a 305 in his 89 camaro, it has a decent amount of bolt ons but still lacks the response that a 350 would general give from such mods

I was also in your shoes in high school, had a 92 RS 305 TBI and I think you should be able to get your car to keep up with LS1's on a budget as long as you have a good bottom end. I would start with 4.10 gears and hooker long tubes with a catback. On the long tubes you'll need to hammer in the floor boards a little. Then go with a dual plane intake and a 750 carb. Comp Cams 249-CL12-209-2 should be good. And then if budget allows go with world products S/R torquer heads and a 75 hp plate system nitrous shot. The benefits of all these mods except the heads are that you can reuse them on a 350 later down the road. If you cant afford to do them all start and learn how to install stuff yourself. With this setup you could see high 12s with a stall and drag radials.

if you want some good fire power for cheap, check this out - If you want, I can give you an ebay (power)seller's username. I bought a billet distributor w/ a 50k volt coil, bronze terminals (the seller, who really a parts store claims it's a 65k volt coil) for under 90$ shipped (and it's all brand new!!!)

anyone posting here with a 305...i've tried, and while it will make some decent power, you can do more with just a little more money.
You'll need intake/carb/dist regarless
build a junkyard stroker and make 425hp, you'll be much happier then the maxed out 300 you'll get from the 305
and like mentioned, if you're young and can't afford to much right now..just do full exhaust and have someone tune that quadrajet
