I know this is the wrong board, but I think some of the Canadian cars are a bit different from the american ones.

I have this Haynes manual, it sucks. The electrical diagrams are all wrong(or american) and this is a canadian car. So I got the engine and the tranny out and now I'm fighting with the wiring harness.

Update: TPI out, carbed 350 going in.

I'm selling the TPI so I can't just hack it up and get rid of it.

Has anybody here have had experience that I'm going through cause the wiring harness is pissing me off. What should I keep:

-water temp.
-oil press.
-stock gauges( what a pain)
- no a/c or heat fan, it got ripped out.
- elec. cooling fan

what else am I going to need off of that wiring harness.

Moderator: Don't close me down, I'm pulling my hair out and going bald over this.

Dave


PS what sucks is when you've only had the car 3 summers, babied it, never took it to the track, supposedly had a top of the line clutch installed after I bought it, come to find out I know need another clutch.

 

its tech dont worry only non tech gets locked and i love my non computer controlled lg4

I really do love my 750 holley .. but those not so nice looking TPI sure pull hard.. Is it a 350 TPI or 305? I might be willing to make the switch if the price is right.. how much you asking?

 

Sorry man! I already have a buyer lined up. He's taking it for a $1000 bucks. I've been working on this engine going in for about 8-9 years now. It was in my fathers car. Instant throttle response. I found that with the TPI there was always a delay of some kind.

Dave

 

What's the new engine got?

 

It's originally a 300hp 350ci with higher comp. pistons. A mean cam and some ported out "882" heads. Edelbrock intake, holley 750DP. Randy's Performance in Kemptville tells me the combo with headers should get me well over 400HP.

That'll be sweet. But I tell ya. Going from EFI to carb, is alot hard than I thought. I'm racking my brain on how to still use the stock guages without the computer or wiring harness.

A healthy dose of NOS could very well be on the way too, if the money doesn't run out.

Dave

 

It's not that hard, the gauges have nothing to do with the computer.

 

LOL, my GTA is at Randy's right now and has been all week

 

Randy knows his cars, but I hope you have patience. This summer my car sat there for 3 weeks before he came to tell me it was just the MAF.

Dave

 

We allways send the tough stuff to Randy's but he needs to be "reminded" sometimes. I have no patience left for this car

 

Ahhh, the things it takes to have toys eh?
There's always something wrong. Whats wrong with it?

I had to pick up a new flywheel because the old one won't bolt up to the new engine.

Dave

 

Keep your eyes open....some of my pushrods may have landed in South Mountain Randy said he has never seen anything like it. You guys should see what chromemoly looks like when it fractures. I hate this ****ing car

[This message has been edited by Acceld Z (edited November 19, 2001).]

 

Holy sh*t dude, you blew the f*cking thing up?

 

No, I just bent most of the pushrods and a few valves. One of the pushrods broke into 3 pieces and was found in the lifter valley. Randy's going to fix it because i'm sick of looking at the piece of ****. Randy honestly said he's never seen anything like it. He can't figure out why it happened either. It WAS running pretty good. I have a box of chromemoly pushrods that looks like metal spaghetti. It looks like modern art.

[This message has been edited by Acceld Z (edited November 20, 2001).]

 

How the hell could chromemoly get mangled like that. The only thing I can think of is maybe the rockers weren't tightened down enough when the pushrods were put in, but then why would it run fine for so long.

Too friggin weird.

 

I have a friend that had a 74 Dodge Charger with a 383. He had the same problem. He went out and bought a set of heavy duty pushrods and these things were thick, about twice the size of a chevy pushrod. He bent those as well. I'll see if i can find out what the problem he was having with his car. It might be the same issue that your motor has.

Dave, did you get that pic I sent you? The rockers where adjusted properly and the push rods are stock diameter. It's Randy's problem now, I just have to pay for it I have zero compression in cylinder 1 so I probably bent a valve or two(or 16). I don't even want to think about it.

 

Yeah, I got the pic, and all I can say is
"What a mess"
Better work some overtime buddy.

 

Hit something on the road today. Could it be... a bent all to hell chromemoly pushrod?

 

Lol, it could have been. I went and checked out the mess last night(Friday). I have a bunch of smashed and bent valves. The rockers beat the crap out of the valve tips. They look like they melted. The neat thing is that the rocker arms don't have a scratch on them.

 

Did you wear down any of the cam lobes?... better check that too...

 

The cam's fine. It's pretty hard to gall a roller cam anyway's. I don't give a **** if I have to tunnel through 5 feet of snow, I'm going to drive this thing this year

 

is it the gta or z28?

 

It's the GTA. At this point I don't know if the Z28 will ever move under its own power again.

 

whats wrong with the z and whats wrong with your lg4 car

 

Well the LG4 car is a piece of ****. I wouldn't be caught dead driving it I took all of the candy off the Z28 and put it on the GTA. What didn't go on the GTA was sold in the classifieds or on E-Bay. The Z28 still has the 383 short block and DFI. I ordered an Accel ProRam and fuel rail kit for it a while ago but I'm concentrating on the GTA right now. Not to mention the fact that I'm broke If anyone needs any parts off the LG4 car let me know.

 

what lg4 parts have u got?

 

What do you need?

 

nothing really just wondering what you have what about interior pieces?
i need a drivers seat mine is torn what colour and condition is it in?

what kind of air cleaner do you have?

is it a trans am and if it is what colour is it?

 

It's a base firebird. It's blue and silver. The interior is grey and the seats are actually in pretty good shape. It has the standard air cleaner for the LG4.

 

how much for the seat? (i am just as poor as you after the tranny so it will probably be after christmas when i can afford to get it

 

does it have a computer?

 

Do you want both seats? I don't know if it has a computer or not. I'll check tonight.

 

They are just the standard Firebird seats. They are not the fancy ones like in the GTA's.

 

I had a thought about what might have caused your heavy metal spaghetti.
If you lost oil pressure for some reason, dirty oil stuck relief valve in the oil filter adaptor, just not enough oil or something the lifters would loose pressure and the push rods would have a lot of slop between them and the rocker arms even enough so that they could fly right out and get munched up. When you said that the top of the valves were badly worn and scored that also sounds like the valve lash went out of adjustment possibly because of a loss of oil pressure. The only other time I have seen that kind of thing happen is when someone does a cam swap for a cam with a tone of lift and they don't check the clearance in the bottom of the Rocker arm if you go over about .580 lift you need to elongate the slot in the bottom of the rocker arms so they don't bind on the stud. Something caused this. Don't put it back together until you find out what. Good luck

Thanks for the input . I'll mention that to Randy. I think it's a matter of me screwing something up when I put it together.
