alright i ordered:

hedman headers

hedman ypipe

borla catback exhust

Mallory HEI Distributor

Iridium X Spark Plugs

Accel 8.8m spark plug wires

summit dress up kit (duh no hp here)

Aluminum (non clutch) fan

edelbrock performer rpm intake manifold (0-5500 rpm)

edelbrock thunder series 650 cfm carb

K&n air filter

K&n oil filter

i also took out all the emissions stuff, the air pump, and put a straight thru pipe where the cat was...

I have a bone stock 305, my dad tuned it up a little, so im figuring right now its puttin out maybe 165 hp, and maybe 250 lb/ft torque.

So with all this new stuff coming, how much could i be putting out now?

Thanks,

Jim

okay get rid of the uridium crap waste of money

the aluminum fan is questionable... doesnt the car have an electric fan?
if it does and it doesnt work replace the damn relay it is $12

the K&n filters are a waste also...well maybe not their air filters but their oil filters are

how much did you pay for the cat back? what size pipe what kind of bends?

gibsongod716

first of all i already ordered it, and the spark plugs are great, ive used them before...

the fan is not electric, nor has the fan ever been electric in a fbody as i am to know...

k&n filter really didnt matter, i just needed a filter, and needed an oil filter for an upcoming oil change...

the catback was 600 from autotruckpart.com, its 3" and this is what it has "YesIntermediate Pipe Diameter (in): 3.000 in.Tailpipe Diameter (in): 3.000 in.Tip Outlet Size: 3.000 in.Tip Quantity: DualTip Shape: RoundTip Cut: SlantTip Edge Style: Non-rolled edgeTip Material: Stainless steelTip Finish: Exhaust System, Cat-Back, Polished Stainless Steel, Chevy/Pontiac, Camaro/Firebird, Kit"</SPAN>

I'd say 250 hp. There was an article where they did most of the stuff you did in I think gm performers or something, go check the rack its probably still there. I'm moving so all my mags are packed up or else id post the article for ya.

Don't expect a lot of HP by your gains, possibly 25-30 max, depending a lot on your (stock?) intake. No 'seat in your pants' feeling. I am pretty sure that thirdgens started in 86 with the electric fan option and if possible I would rather go that route, less accessory load. I can't say how iridiums perform, never ran them so I can't give any input on them. On a rather stock motor, I would prefer to keep it with the stock plugs. AC Delcos haven't ever proved me wrong before (don't run platinums, not trying to start the "Which plug is better" flaming thread here either, haven't had good results with them, besides its 1 spark to the contact with less resistance, so who cares its still 1 spark).

There is no way with what little has been done to account for 250 HP, not in my book. Most 350s stock put out less than that.

gibsongod716

really, i was hoping for 230-250 like what rayzor said... is there anything else i could do to it to increase the hp? Id rather stay away from heads and cams, had a long talk with the old man and he said "if your buying a new cam, im putting it in my nova..." My dad does know a lot of tricks he can do with the engine tho, he made it run a 13.8 in the 1/4 and its a freaking 305...my best was a harsh 15...

Oh oops, I thought you bought heads too. I'd say about 205 now. Get some heads and a cam.

The headers are probably good for 10-15hp, then the exhaust is another 10-15hp. The kn is like 5. The intake and carb are probably good for 20-35hp. Damn i may go unpack my box and get that magazine cos they took a 305 just like yours and did basically all the same upgrades (but heads and cam too) and showed all the dyno numbers and et for each step. You will DEFINETLY feel a seat of the pants difference. Get heads, cam and a stall converter and you'll tear it up. I got 305 tpi w/ dart al heads, roller rockers, k and n, edelbrock headers, 3 in flowmaster exhaust, msd dist, msd digital 6, msd wires, and ac plugs, and a crane cam and a 2800 b and m stall and performance pistons. I'm getting at least 300 hp.

gibsongod716

^^^^ thats good news! at least maybe ill make it over 200

ResurrectingZ

Not to say a 305 is junk, they can be rather impressive with the right build, there are several members on the boards who attain a lot more HP on a 305. Try looking up the casting numbers on your heads, they may be crap or with the right workover may be something worth working with. A cam would also benefit you down the road as well. Post back up your head casting numbers.

Iridium's and carbs don't seem to get along that well.
I used to work at a parts store and though i won't mention it's name coughAUTOZONEcough we would try to sell the Bosch Iridium Platinums strictly because they were $10 a plug when an AC Delco resistor which is probably better for your motor anyways cost $1.99. If you really wanted a platinum plug i would probably do an AC Delco plat. Come on who knows Gm's better?... I have had great experiences with just the stocker Delcos... but i must say I'm giddy to try their rapidfires.


Now if that were my motor i would port and polish the heads(at a minimum)

maybe add exhaust cutouts...but hey that is to strictly **** of the neighbors

Also, my 92 3.1l has dual electric fans.

gibsongod716

i suppose i could get a cam, i know which one to get, but thats alot of work, cuz you have to get new rockers, lifters, retainers, springs, and all that crap, not to mention, im not pulling the engine for this job ... the heads are a completely different story, i suppose i could get some off ebay or soemthing, but at this price i could probably get a crate putting out 300+ hp(discounts discounts discounts!)

I wanna try the rapidfires too, since my msd isnt working right and is unhooked. Gap those plugs at .040 or .045, you should be fine at 45 but might as well be safe and do 40. BOSCH SUCKS, the guy at autozone said i should get them and he had them on his z, those platnium fours are marketing bullshit they work good on imports not on our cars, its like the gillete razor, 1 blade worked fine, you dont need five, just like you dont need those bosch 4s. I still say regular AC delco's are the best, ac makes good stuff, accel, autolite, and ngk have all worked fine for me too.
----------
I know the prices are ridiculous, id say you'll be happy for a while with that new stuff, the heads and cam are down the road w/ those other possible options. Did someone say zz4 swap??

gibsongod716

alright, my spirits are back up, ill get the head numbers later its a little dark out and my car isnt apart yet lol... thanks guys

SpitotRs305

okay i think i have said this a few times... the home mechanic is not capable of gapping iridium plugs... the gap is specd in the part number for a reason...
the tiny tip of the plug eliminates the use of any feeler gauge as the tip will crack very easly even if you dont see it fall off it is cracked and it will fall off or burn up...

the regular ac delco plugs will work best for a stock or near stock application... even for a fairly stout engine i would only change heat range...
and the AC delco can be gapped as large as any uridium plug in a stock N/A engine
-----

you wont need new rockers for a cam, you can find a cam that will work with the stock valve train..., cam swap can be done in car with removal of the radiator and so forth, will yeild better results if you swap the cam along with the rest of your mods... then your heads will need some work depending on what they are... you can always find vortecs cheap, i paid 300 bucks for a complete pair... trick is when you go the they J/y dont say a damn thing about vortec anything... say you need a set of heads off a 96-98 350 pickup ending in 062... some say the 062 flow a little better then the others. they will drop your CR a little but would be worth it with the new cam and other mods. but then you would also need a new intake specail for the heads

Toehead

The fan for a lot of F-body cars is electric.

gibsongod716

exacxtly^^^ my manifold i picked up doesnt work with vortec heads, but i suppose somewhere down the road i could pick up a new one and sell the one i got

SpitotRs305

you can get a vortec intake for like 150 bucks

gibsongod716

cool ill take a look tomorrow for some heads, got a lot of junk yarks around here(NJ)..

Razor... i agree with you 100% i hate Bosch. They don't work good with GM. I would constantly tell people that while working at Autozone and they'd give me some bs story on why they work better and two days later they come back in B*tch me out because their plugs suck. Also, personally I would never use anything but a resistor on a carb anyways.

Gibson, hope your camaro becomes a powerhouse!

gibsongod716

camaro firebird same thing lol... once i get it hooked up ill take some pics and dyno run it and post it up here

Lol my bad, it's just half the parts you listed i already have installed and i kept thinking about my car but maybe subconsiously i want my car to be the powerhouse

You are so right its not even funny. I um know a guy lol who works at autozone haha and what "he" told me is that bosch is total crap. I ran um oops I mean "he" ran platinum 4s in a GTP and lost .15 in the quarter; put in autolite 103s and picked up .2 lol. Alot of people are blingsmerized by shiney packaging. Stick with factory spec or proven otherwise its most likely a joke.

BTW I just switched to AC rapidfires from platinums and felt a nice increase in power (not to mention .5 mpg increase) .

gibsongod716

oh man todays the big day, im gonna start on the headers and ypipe, btw the intake i ordered is a high rise intake, and i really dont think its gonna fit, however, i have this custom made hood which rises up a little, i think 2 inches higher with some holes on the side
it looks like this(side view)(sorry but its a crude drawing)

front.....................................rear(windshield)
........./-------------------------- |
-----/..o...o...(carb)....o.....o....... |2 inch ignore the periods i had to use that instead of spaces!

i think that its gonna be good cuz the carb and filter are right where the holes are so its gonna be getting some good cold air...
