871  Camaro Research Group Discussion / Decoding/Numbers / Re: Dual Fuel Lines on: March 16, 2007, 10:28:36 PM
Your right I don't know if the car was originally a big block or not, just like you don't know it was.  

I do know that no L35 made during the 69 model year was equipped with a single fuel line.  GM would not send a car out of the factory that required two fuel lines equipped with a single line.  The dual fuel line was there for a reason and it wasn't for looks.  There was no engine fuel lines that would have connected the fuel pump to the rochester carb that didn't have the return line on it.  The only big block with a single fuel line was the L78 which used a holley carb.  We know its not an L78 because the engine has and L35 assembly code.  The Holley fuel line will not fit onto a rochester, and the guys on the line really weren't in a position to be making up parts to make a car with a mismatched fuel system work.  If the car mistakenly came down the line with a single fuel line it probably would have taken them 15 or 20 minutes to get the dual lines installed if the car needed it.  Could some previous owner have pulled out the dual fuel lines and the tank pickup and sender assembly and replaced it with a single line setup the day after the car was bought, sure they could have, but I would say the chances of that happening is way less than 1%.  Could some previous owner have put a big block in a small block car, and a big block heater cover, sure they could have.  Which of these two events do you think happens more often changing a fuel pickup and fuel lines or putting a big block in a small blcok car?

At the moment we know the car has an L35 engine, a big block heater core, a replacement transmission, a 3.07 posi 12 bolt axle power disc brakes, and a single fuel line.  Throw the JG engine code out and most people would say its an L78 as thats the only big block that could have a single fuel line.  Add the JG code and most people would say its a clone because no L35s came with a single fuel line.  As I said before theres not enough info to make a definative judgement at the moment, heck we don't even know the VIN or trim tag info beyond its a 12A Norwood car.  It could be an L78 that someone put an L35 in for all we know.  The only thing thats sure is the parts in the car right now, don't match what left the factory, be it the fuel lines, or the engine.

Doesn't really matter, there is no sheetmetal instructions in the Z22 section.  The fenders, while they are different, they assemble the same as the non RS  fenders so they are not illustrated.  Same with the rear panel, it was already on the car when it came to the GM side, so all they show you is the backup light assembly and the hole it goes in on the tail panel.  The only dimensional info you get is for drilling the holes for the rallysport emblem on the front fender.

If you were putting a big block in a car back in the day, would you have pulled out an extra fuel line if it didn't interfere with anything else you were doing?  If you put a rochester carb on a 2 BBl engine would you put an extra fuel line in just because the factory did it that way?  All I'm saying is that people don't usually mess around with things on a car when they are making changes to a car if they don't have to.  I just use the "FACTORY" method of installation to try and figure out what a car was originally using whatever clues are available.

So far we have a big block in a camaro with a 3.07 rear axle 2 fuel lines and an automatic transmission that was replaced years ago.  The assembly code on the engine is dated prior to the build date of the car, but I've not seen the stamping on the pad, so I won't use that as evidence to say that it is original until I see a picture of it.  A 3.07 axle ratio is the economy ratio for a small block SS, and the standard ratio for a big block SS, so that doesn't help.  2 fuel lines were used on the L48, and the LM1 when this car was made, so thats 1 point for the car being either an L48 or LM1 originally with a big block added later.

Do we know for sure if its originally an SS at all?  No, we don't hence the questions on the location of brake line brackets, and there is a difference in the bracket locations between drum front brakes and disc front brakes.  Someone who doesn't change the fuel lines when the put a big block into a car certainly wont change the brake brackets.  Do we know if there is a dual exhaust bracket on the driver side sub frame?  For all we know the car has a small block heater cover as that hasn't been mentioned either.

It makes no difference to me if its a big block or an L6 car, I'm just trying to help someone figure out what they have.  alot of what is needed to do that is visual, and if you can't see it you have to ask questions.  If the evidence points towards small block then thats the way it goes, if it points towards big block its a win for the owner, but right with the info in hand I wouldn't pay big block money for this car if it was for sale.  Need more info to make an educated decision one way or the other at this point.

The front lighting harness goes under those two straps, it doesn't go between the inner and outer fenders (at least in 69's).  In the 69 AIM its shown on UPC 12 A4, which says its for an L6 but every car was built that way.  The only difference is on the V8's (in 69) the generator harness is on the passenger side.

The ONLY way to tell if you have an agreed value policy is to look at the wording on the endorsement.  Don't take your agents word on it, make sure you know what you have.  If the policy says in the event of a total loss we will pay you the amount specified (and the amount specified is what you agreed to), or we will repair it with like parts up to the value of the amount specified then you have an agreed policy, end of story.  If there is any wording in the endorsement about depreciating it, or value on the date of the incident, or the term like value is used then its not an agreed value policy.  There are two examples of agreed value policy wording in this thread, what does your endorsement say?

Block cast on nov 1 1968 assembled on Nov 30th 68 with November 29th cast heads.  Yes blocks and heads can be cast on one day and assembled into a motor the next, or even the same day if they were cast early in the day and assembled late in the day so thats not to odd.  So can we assume that this would be a 12A Norwood car (Is it a Norwood Car?) at the earliest?  3.07 is one of the standard small Block SS axles (economy, I beleive) as that is what I have in my car.  Not sure if it was one of the standard ratios for a big block or not though.

Have you looked for a crayon marking on the front of the rear package support, behind the back seat?  You may find an X code back there, like X1, X2 or a combination of exterior color and X code together like RG2 for Rally green X22.  The codes were pretty common in the November time frame on Norwood cars anyway.
877  Camaro Research Group Discussion / Decoding/Numbers / Re: Dual Fuel Lines on: March 12, 2007, 09:35:29 PM
No reason, most people don't give the fuel lines a second look.  Every small block except the LM1 and L48 and both the L34, and L35, have a single fuel line.  It's much more likely that the engine is not original than to find an L35 with a single fuel line.  When was the engine assembled?  How about the stampings on the tag on the pasenger side of the TH400 transmission.  Whats the rear axle ratio, and assembly code on the rear axle?  On the front end, where is the bracket for the front disc brakes rubber lines going to the wheels, on the top of the frame, or on the side?
878  Camaro Research Group Discussion / Decoding/Numbers / Re: Dual Fuel Lines on: March 12, 2007, 05:32:52 AM
Nope, the only big block with a single fuel line is the L78.  The other two (L34, L35) have two fuel lines.
879  Camaro Research Group Discussion / General Discussion / Re: Differences in CE and DZ block on: March 05, 2007, 08:32:55 PM
Look at the casting numbers on the back of the block.  They are probably different, a 68 block will be 3914678, while 69 blocks were either 3932386, 3932388, 3956618 or 3970010, depending on when it was cast during the model year.  Oh and 68 Z28's didn't have DZ coded blocks, they had MO coded blocks.
880  Camaro Research Group Discussion / Restoration / Re: 68 Air Conditioning -Sealing on: March 03, 2007, 03:18:42 PM
Thats a 69.  The front baffles weren't used on 68's until sometime around April of 68. If you really want an exercise in futility try finding a convertible baffle.  I've only got one for my car and have been looking for the second one for about 6 years now.  I guess I should just take the one I have down to a sheetmetal shop and see if they can make me a mirror image of the one I have.
881  Camaro Research Group Discussion / Originality / Re: Chambered exhaust on: March 01, 2007, 12:18:27 PM
The chambered exhaust was only available on Z28's and big blocks.
882  Camaro Research Group Discussion / Restoration / Re: stickers on core support and fan shroud 0f 69 z/28 on: February 26, 2007, 12:21:12 PM
Probably not, since the crossram didn't come from the factory, and the dealers would not have been required to install such a label if they did the installation.
883  Camaro Research Group Discussion / General Discussion / Re: Speaker / rear defogger on: February 25, 2007, 03:36:13 PM
Speakers go between the air vent and the front edge of the door opening.  There is a rectangular opening in the substructure of the car that the speaker magnets fit into.  You have to get the speakers installed in exactly the right location or they won't fit.  If you remove the kick panel you can measure from the edge of the door opening and up from the floor to the center of the rectangular opening to establish a centerline for the speakers.  From there you can make a template from the speaker cover to locate it correctly.

You will have to use an OEM style speaker in this location as there isn't much room for a large magnet in that rectangular opening behind the kickpanel. 
884  Camaro Research Group Discussion / General Discussion / Re: Exhaust resonator...what does it do? on: February 25, 2007, 08:34:12 AM
The resonators are two small mufflers about 16 to 18" long that go in each exhaust pipe before the crossover muffler.  I beleive they were used in late (around May of 9) 69 Camaros with dual exhaust.
885  Camaro Research Group Discussion / General Discussion / Re: Car Insurance on: February 24, 2007, 07:54:37 AM
You establish the value in an agreed value policy and the rates you pay are based on that value.  Some companies require an appraisal to support the value that you want, others don't.  Most will require a series of photos showing the car exterior and interior.  I have Hagerty and I picked a value, and they aggreed with that value without an appraisal, so my value must have fallen within an acceptable range for what my car is.  I need to boost the value this spring when the car hits the road again.
