Just as the title states, i did a bit of research but nothing really was close to the question i'm submitting...the person that owned the car before me overtightened one of the water outlet bolts at the front of the intake. The other one came out perfectly fine, but one now has a head broken off. I have tried vice grips, i've sat there and PVC blasted it for a week straight, i've tried getting two nuts on there to lock together and unscrew, and finally i've tried grinding both sides to be able to get a better grip instead of stripping the threads, all to no avail. for ***** and giggles i've even tried jb welding the head back on. I've tried heat and that doesn't seem to want to make this bolt move, all it does is start to twist just like the screw was aluminum or something, it's just weak.

My question is: is it worth the time of taking the intake off and trying to drill it out or sending it out to drill it out??? My engine is a 305 now, if i was to purchase a new intake, is it transferable to a 350 later on??? What would you suggest? If your opinion leads me to buying a new intake or finding a used original one, what model and brand do you suggest, if i'm going to spend the money i would like to open her up a lil and let her breathe easier, but i don't want to break the bank!! Any help or leads would be great. Thanx!

have u tried easy outs? I broke 2 transmission bolts on my nissan and i went to the local hardware store bought a titanium bit and easy outs. drilled a whole right in the center of the broken bolt tapped in the easy out into the drilled hole i made and it unscrewed easily. But on yours it sounds kind of like its sticking out and is in there good so not sure if this may work but its worth a try and well it worked for me. Good luck

It's not from overtightening the bolt that caused it to break. I had a 83 crossfire intake do this and my TBI intake when I last changed the thermostat when I lossened the bolt it was very rusty. I think the do it when they have thermostat housing seapage over time and it siezes the hell out of the bolts.

Just buy a used manifold by the time you mess with getting the bolt out or paying to have it done it would come up to the price of a used edelbrock manifold.

If you do manage to get the bolt out put a stud in the bolts place.

Oh and a used edelbrock smog replacement manifold works great on a LG-4 had one on my 82 think it was a edelbrock 3701 if memory serves me right.

If the broken bolt isnt causing any harm then i would just leave it, especially if you are looking to swap intakes ,which is probably your best bet. you can pick one up fairly cheap on ebay, i believe edelbrock part humber is the 3701 as previously mentioned.

yea i'm trying to stick with my stock intake if anyone thought it would be worth it. I thought of that easy out idea, but i couldn't get a drill bit to stick on the top of the bit, i flattened it out with a grinder, got a pointy nail tap, made the indent, and still coudln't get the drill bit to stay still.

As far as it being in the way, i need the second bolt to tighten my water neck back onto the intake so i can start the engine. I wasn't planning on swapping it unless people felt that after the countless hours and many broken drill bits, wasting money and swearing a lot if it would be cheaper if i would just go aftermarket intake.

Yea this car needs to be legal on the steets so i'm assuming it needs smog, i'm in NY and getting told i live by california regulations so it needs to be legal however i set it up.

Back to original question, if i invest say $200 or so on a TBI intake for my 305, is it transferable to a 350?? If they were transferable, that would lead me to get an aftermarket as long as i know i'm not throwing away money into something that is only good on a 305. With that edelbrock intake do i need a carb to tbi adapter i keep reading about with most intakes??? Just wondering and keep the ideas coming, i'd like to look into more than one company if anyone has any good experience with them.

Have you tried a j-yard, the classifieds, or ebay? Might be easier to just get another stock intake. Theyre not exactly hi-po parts, so people should be willing to unload one for cheap.

exactly what you'll be doing !!!!!!

probably spend as many hours fighting the bolt issue then probably have to put in a heli-coil cheaper and less time consuming to just put another intake on.

ok if i was to buy another one, aftermarket OR used original, does a 305 work on a 350 and vice versa? Cause i wouldn't mind picking up a 350 intake to throw on my 305 if they'll throw the TBI in there so i got the 350 injectors.

has anyone else delt with any other company other than edelbrock?? If so please include company and model number if you can remember it.

It says it will transfer to a 350. Not so sure what kind of gains you would see with it on a 350, but at least if you were to have the same problem again you would have a spare. Unless you are doing a TPI 350 or a Carb they wont use it.

ok, if i was to go to my local junk yard, is there any chevy truck v8 or car v8 fuel injection system worth seeing if they have if i'm possibly going to have to replace the top half i know i'm jumping into a whole nother topic, but is there any other car other than corvette running TPI or MPFI that would be worth it for my 305 that if i'm going to invest money i might make a little bit more HP for my investment?

ok, did a little research on that edelbrock 3701 and came up with this auction:

http://cgi.ebay.com/ebaymotors/Edelb...spagenameZWDVW

It stated down below to what applied to me:

Make CHEVROLET
Engine Type V8
Engine Size 5.0L/305
Liter 5.0
CID 305
Beginning Year 1976
Ending Year 1986
Engine Family Chevy small block Gen I
Carburetor Mounting 4-barrel spread bore
Cylinder Head Style (application) Stock configuration
Application Notes EGR spacer required on centerbolt heads with 1986 and earlier bolt pattern.


87 or 88, didn't the intake/head bolts start going at a different angle??? And is my original '88 305 a "Gen I" small block? And will it have provisions for all the other emissions equipment i got? The title stated EGR N/A like it was without, but then it says that a spacer is required???

Anybody got an intake kicking around???

Sorry didn't realize you had the LO-3. Thought it was a LG-4

The pre-87 intakes didnt have the angled center bolt holes to clear the pushrods there. You can use a carb intake, and its just about the only way to get a true performance intake for TBI, but itll require that you use an adapter plate and make some other modifications. The edelbrock performer manifolds are good ones to use as they have most of the provisions needed, but still require that you mod some stuff to get it to work.

I thought i read about a difference somewhere in that area...ok so my only alternative other than swapping in a TPI system being i don't know of any other FI system avalable to this engine if there was one...is to go find an orignal intake? What other provisions would i need to make in order to use a performance intake other than the adapter?

I had the same problem as you. My OEM intake thermo housing bolt snaped. I spent a week twisting, drilling, boring, etc. before I finally got smart and went to the J Yard and got an OEM for $30 and put it on in a couple of hours. But the difference was that was in the summertime. I wish I had put studs in but the next time if it happens again I will go performance. I imagine at some point this summer I will have to change thermostats. I will PB Blast it first and if it breaks I am making the switch to the better intake. But for the puposes of getting back on the road (and my pockets)the JYard had a beautiful intake and after cleaning it up and some aluminum spray paint a year and a half later it works great. I was peed at myself for spending time and money trying to drill that bolt out. Never again...

lol thanks for the input! yea i'm all of about to give up, i have been so busy with finals i haven't even gotten my intake out yet, but i was going to try and drill it with a press before i went out and bought another intake but, yea that was probably what i was going to do. Just gotta head out to the JY this week. Thanks!
