recently i bought a summitt racing "stage 1" intake for my 88 firebird. I figured id save a few bucks. BIG MISTAKE. when i got the intake immediatly i found a black resedue like sand that was clumped in the ports, i had to use a screwdriver to remove it. the ports temselves looked like a 5yr old milled them, after doing a gasket match on them i removed about 1/4" from each port.
Spend the extra 30$ and get the edelbrok

I doubt they would accept the return now that he ported it out.
However, I wonder if they would have taken it back if you had called right away, before attempting to fix it yourself?
I am sure if you mentioned that it was still full of casting sand they would be reasonable. Maybe they could upgrade you to the edelbrock or something.
Did you happen to see a brand name cast into the intake? Or does it say summit?

I bought one of those manifolds from summit and it was fine . I blew it out and cleaned the gasket surfaces and it works fine. I had none of that black debris in mine maybe you just got a bad one-it happens. I bought summit wires and those are made by taylor so yes there is some things that are "name brand" with a summit logo onit. But there are some things they sell as summit brand tha are junk-live and learn
well i live 10 minutes away from the summit in mcdonough, ga .. lucky me .. haha ..
i find it pretty convenient to just go and pick something up ..
but most of summit "brand" stuff is actuall name brand stuff .. kinda like walmart has "great value" brand which is the name brand stuff in a different box ..
if your not sure on something then call one of the summit stores and they can tell you who's brand it is .. every time ive bought something "summit brand" the guy has told me who actually makes it .. like summit heads are trick flow .. and summit air filters are k&n
yeah, in order for me to return id hsve to pay for shipping, pay for a better intake and hope to get it intime. ill just complain and port lol. i get a lot of summitt brand parts due to the fact im budget racing. This intake is the same spec as the wiand intake for post 87 sbc. but no where near wiand quality.
For those looking at this thread, more issues today. The item discription says "will work with HEI distributor", i even called and asked, will the vaccume advace on any dist, clear the intake for a full rotation? they said yes. THEY DONT!!!!! so now i have to pull the distributor, set back a tooth at a time till i get my timing right. o well thats what i get for being a tight *** onmoney

there are no sbc intakes that will clear a vac canister on a hei for "full rotation" - that has nothing to do with the brand.
hey dont spend 180$ or what evr on and after market intake.....do what i did make your own for $40!! just got home depot or true value or lowes and pick up some pvc piping, then go to advanced auto parts or auto zone and pick up some performance air filters....its worked fine for me

Reason: Automerged Doublepost
If you want to turn your dist past your intake just move all your wires by one space....

he is talking about intake manifold not cold air intake...
dang .. i guess soon were going to be buying plastic headers / cams / heads / etc
i thought it was pretty funny when i saw "with plenty of MATERIAL (plastic) left to port" under the ls1 intake manifolds
dude...before you bash something why don't you think about the actual theory behind it?
1 - they came from the factory with composite intakes...pretty sure GM has something figured out you don't.
2 - Composite doesn't conduct heat worth crap, meaning cooler denser charge, aka more power
They make composite manifolds for SBC's...they also make composite carb spacers to keep the heat down. It's not that complicated. I hope you get smoked by a car with a composite intake...just dont come cry about it here.

There are some down sides too. Lest ye forget the beloved 3800 composite intake that loves to flood and lock up engines. In my case, i sweat and toil over the yodas, on our 1azfe engines from the matrix and the corrolla the intake likes to leak on cold startup in sub freezing temps only. The intake and head heat at different rates and during the warmup period only they leak. talk about a pain. Get a lean code, with absolutely no lean condition. This happens with more than toyotas though.

yep, GM's 3800 and Ford's early(non-PI) 2-valve 4.6 manifolds all now have Dorman "improved replacements" available. There are several others as well. - By the same token, I've seen plenty of TPI bases that leaked also.
Wilson is the first company that comes to mind making composite manifolds for regular sbc's. Not cheap, but horsepower never is.
As of yet, there is no aftermarket intake that will make any more power on a PI 2 valve 4.6 than the factory poly intake. There are several companies that claim to, but I've seen back-to back dyno runs(on a 330+ rwhp 2-valve) that proved otherwise. Some did make slightly more peak, but at the cost of average power. The "p-51" did have a decent gain, but it's weight off-set any actual gain at the track.
A good cheaper SB Chevy intake manifold is . The Professional Products Cyclone # 52001 . This intake is very much Like the Edelbrock # 2101 . You can buy them at www.competitionproducts.com For $114.95 This intake will also fit the early and 1987-up bolt angles . It comes with adapters to do so . The one I have looks good . And I can use it with my 1990 #083 5.7 TPI heads .
was tryin to find the oil filter on my dads new chevy hhr today (still have no clue where it is) .. but i noticed the intake manifold is plastic on it too, and there is nothing except wires going to the throttle body .. does that mean the throttle is all electronic now .. guess that eliminates a TPS ..
i think ill stick with my 91 camaro .. lol .. feel sorry for mechanics these days b/c i have no clue how they change the accessory belt on them things .. talkin about a tight fit ..

drive by wire...its standard on a lot of stuff now

That intake is the biggest POS out there. I got one. I had to grind the top flange area on both sides to clear the valve cover rail on my heads (stock l98 iron)
The adapters actually split when I tourqued the intake.
The ports are way smaller than stock, and they are so far off center, there is not enough material to port match them.
Competition Products would not exchange mine for a name brand one because I had scribed it to port already.
i bought the edelbrock vortec tpi hi-flow base .. its a very nice piece .. and fits like a charm .. almost got 1300 miles on it and havent had any problems ..

I can post pics of all this.
Maybe mine is a newer on but it's fine . And fits great ?

Yeah, drive by wire is cool. Actually, they didnt really do away with the tps. Now they use two APP(accelerator pedal position) sensors, one that sweeps 0-5v and one that sweeps 5-0v on most vehicles. Then at the throttle body there is an electric motor to turn the throttle blade, and usually as least one sometimes two position sensors for the throttle blade. The cool part is though, now cruise can be controlled this way and everything. IAC can be achieved through drive by wire also.
i think they offer a 2.0L and a 2.2L (if im not mistaking) .. and i think the bigger one has a form of variable valve timing
its a decent motor, especially for stock .. pretty quick off the line, and im pretty sure theres a turbo version now ..
since its an ecotec, you wont find a spin on oil filter. it uses a cartridge element that you replace. With the hood up, look at the plastic intake. On the drivers side, at the front corner of plastic intake, about 3 inches under it you will see a plastic cap with a big plastic "nut" made onto it. To take that off, and the filter is under it. Make sure to replace the o ring seal.
figured id update on how bad this intake is, Nothing seals. i havd to double intake gaskets and put a halinch of rtv around the distributor, and front and back seals. just to get the oil to stop seaping through. all of the intake bolts leak oil thru. verry disatisfied. not to mention my buddy has same heads cam and everything i have on his firebird, but an edelbrok intake, lets just say he smokes me by almost a full second at the track
