I think im gonna be sick!
I spent hundreds of dollars and countless hours taking out my 2.8 and taking out a 305 just to find out now that the 305 is only rated for 10 extra hp I did all this for nothing!!!!!
83 Z28
Trans Am M5,A4 LG4 V8 8.6:1 5.0 (305) 150@4000 240@2400 4bbl 3.23 3.73 3.23
I originally bought this car because someone told me it was a 350 and as stupid as I am i believed him and I guess the butt &^$^$*# never ends....
There is no hope is there?

Exhaust, cam, air cleaner will wake it up. You can do better than the 190 HP of the L69 with those things on an LG4.

That is very good to know, since this engine is temporary, and I want to save up to do everything right instead of putting a junkyard 350 in. what kinda style headers, long or shortys?

Shorty Headers
nelapse,
Suggestion: There is a great deal of info on the Exhaust Board about shorty headers. My son and I reviewed the material and decided to go CHEAPO and purchased a set that was NOT on the "RECOMMENDED" list. We're now paying the price as they fit poorly and are constructed poorly...... We wasted our money on junk. Save your $$ and wait if you have to..... but buy a good set that will be there for you when you get the 350.
Sincerely,
Kurt

Thre's a pretty big debate on here about 305's versus 350's. You can massage some pretty good power out of that 305 if you do it right. Might as well read around a bit and see what you can do before you do the old "tear out the old for a new" dance again.

Hey man, I live in Garden City and there are a few others of us thirdgenners around in Savannah. PM me and we'll get together some time.
As far as the advice you have gotten- put some exhaust on that thing, it can all be transfered to the bigger engine you may replace it with.

Different headers. I had a set of hedman shorties, and the collectors sucked. The flange was a 3" 3-bolt spin type on the header, and after changing a gasket once or twice it was hard to seal. There was not enough meat there. I don't know if they have changed, but I justed looked at the pic on summit, and if the header has a ring on it like the one in the bottom of the pic, forget it. I have never used the hookers, but they get rave reviews here. I have SLP 1 3/4's, and they take a donut gasket and it works great. Go to summit and look at a pic of this: HOK-2055HKR. Same principle but without a gasket. For the $$, that's what I would get. And don't forget a converter or a test pipe to connect to the new exhaust. Just looked at your exhaust part#. DON'T get that one, it's only 2 1/2" pipe. You need a 3" system. Pick something else. You can order parts for an 89 camaro with 5.7 single cat to get what will work best.

I'm running the 68470's and Hedman's y-pipe, it's a ball flange on the headers and I was told by Hedman that I didn't have to run a gasket on them. I'm running the headers and y-pipe on an LT1, it will flow fine.

The reviews Ive seen on here is that the Hedmans are decent. and as cheap as they are and to be considered decent Im for it. As for the catback... well, I might just get rid of the dynomax idea and get the flowmaster force II. all the other things seem good?

Okay you talked me into the 3" system I will order HOK-2055HKR and flowmaster catback FLO-7151, its just a couple hundred extra for quality so I will get it. But the HOK-2055HKR system is only for 86 and up, I have an 83 LG4 in my car. Will the flanges that bolt to the heads match?

Okay So heres the deal with the exhaust, I was fortunate enough to get a summit sales associate that new quite a bit about third gens. So, I got the Hookers and the Y pipe, but he paid close attention to the description on the dynomax and found out that the dynomax catback was 2 3/4'' not 3. Something the catalog did not describe.
So then I decided on the Flo master, but the 3" catback has a single output not dual. My associate said the single output gives you more horses but just doesnt look as cool. However, i still wanted Duals.. the next one he had was the flowmaster american thunder which was like $340, about $100 more than the force II. After much deliberation I found the Edelbrock 3" catback system for $280. I went with that. Flowmaster is cool, but sometimes hearing is vital later in life.
So the list is in gentleman, $1093.93 worth of carnage. My weekend is booked it should all be here in a few days. I saved up a couple hundred for the little things I know I am forgetting to finish up my swap. There is always... little things..

If you don't have hood clearance, it's probably worse than useless, since the pleats reduce the clearance above the air horn.

If you still have the stock single snorkle air intake DITCH IT! I've never had my car on a dyno but when I switched to a dual snorkle intake from a H.O. car ,I did notice a SOTP improvement and that was before I did any exhaust mods. Look in the classifieds or ebay for one or check out one of the tech articles on how to fab up your own, it'll definately be worth it.

Okay so I wont get the xstream lid, but I wont get a dual snorkel, I think I will stick with the basic top lid K&N, hell they sell K&N filters for our cars at walmart now for $35. Imagine that...

I would stick with a dual snorkle, with the K&N open element under the hood, all you will be doing is sucking hot air into the motor where you will be pulling cooler air using the snorkle.

This hot air cold air thing is Silly, if cold air was really better then we would all have 10 second cars in the winter.
Now there are exceptions. When I was racing imports you have the cold air intakes... its not really about cold air its about the velocity. which would make the air move quicker. In a four barrel carb, its about CFM not temp.

Cold air is denser than hot air, and contains more oxygen, which in turn makes more power. I agree with running a dual snorkel also along with a K&N filter.

Besides, I placed a ball of clay ontop my aircleaner and shut the hood. I have over an inch and half of space from the hood, which would make the xstream lid work. Another thing I thought about too would be that the lid would keep your cleaner from getting dirty quicker. since air is coming from all over.

The dual snorkel will restrict the air clearn by far, compared to an open element with the filter top plate. Theres virtually no resistance compared to the dual snorkel...
This is a difficult decision.

The engine will get all the air it needs with the dual snorkel.
You're allowing yourself to be a victim of the "bigger is better" mindset.

Bigger usually means spending more money for no gain.
Don't flip the air cleaner lid over, all you're doing then is creating a restriction over the air horn.

well it kinda sucks, I already placed the order of that massive list and the air cleaner is on its way, how much is a dual snorkel anyways, and didnt they just come on the L69's?

A dual snorkel will cost more than that lid, and it is the factory one from an L69. I would do a search, someone has a post or two about making your own. Just send the lid back for a credit after you get it.

Hey- flipping the lid wasn't a serious suggestion but it would probably still be better than the money spent on the filter lid.

Well I have sent a total of 1800...
$200 for the V6 firebird
$250 for the donor car
$1200 so far for performance parts and parts in general
$150 for the windshield i accidently broke.
Im not gonna waste my money on the snorkel right now, about the top lid cleaner I had already bought, im not sure if im keeping that or sending it back I will have to review their policy.
I still need to buy an Altenator, (maybe bracket too)
a LH brake line, and a few more gaskets.
Also a tranny filter and fluid and probably some hoses.
You cant really estimate how much this crap will cost you. I jumped into this thinking it was easy and cheap... Its not hard...
but if you want it done right, it is time consuming.. I have a lift and every tool you can think of and its still time consuming. But then again I am doing this myself and I have never pulled out nor put in a domestic engine before..

Well since you said you just sold your eclipse im guessing you have at least $2k to play with here. If it were me, id just suck it up and drive the **** out of the little no ***** 305 and in the meantime be looking online and in the paper for a 350 that someone has already built and is selling for cheap. Lots of good deals out there, my buddy recently got an all forged 406 roller motor with about 20,000 miles for like $1500. He sprays a 200 shot all day long with no probs and is well over 600hp. Save youself some money, get more horsepower, buy an already built motor that someone is getting rid of
