Winter Project...

[WILMASBOYL78]

Been doing some winter maintenance on the black 70 L78 4 speed car...getting ready for the Florida Mini-Nats in Orlando. Water pump was going so I got a correct dated unit...decided to take care of a few other things while I was in there. The original fuel pump had a crack in the fitting (too much muscle) had it rebuilt...also going to re-install the original smog pump and hardware. Took some photos of the parts and collected some numbers for reference...if someone needs a shot of something let me know...I'll try to get it. Neat old car http://www.yenko.net/ubbthreads/images/graemlins/grin.gif

Original Harrison 3 core ZD radiator...tank has OO stamp and L for the month...I assume they threw out "I" so that would be Nov/69...I took the tag off and keep it in the file of car stuff...they are so fragile and easy to loose...top rail between tanks is the original harrison piece with the slotted holes where they hung the rad for painting

Tom!

Are those 2-piece rotors I see there? I thought they were
phased out in late '69 production. How did a '70 Nova get
a set? Is this unusual?

This is a 12/69 car...so the parts were made before that...don't know when the transition took place...as far as I know they are original.

Two-piece rotors were used into the '70 production run of Novas. My car had them, and I've had 70 parts cars with them.

Great pix. This is FAR more interesting than anything on TV. http://www.yenko.net/ubbthreads/images/graemlins/worship.gif

BTW, I'll take one of those autographed photos.........(but how did you train the car to write? http://www.yenko.net/ubbthreads/images/graemlins/hmmm.gif http://www.yenko.net/ubbthreads/images/graemlins/wink.gif)

[WILMASBOYL78]

Made some progress today while I was waiting for my sweetie to return home....got the fuel pump, water pump and smog pump installed. Forgot about the water pump fittings http://www.yenko.net/ubbthreads/images/graemlins/frown.gif....have to get a couple....the old ones have been in their since Tommy was a young man http://www.yenko.net/ubbthreads/images/graemlins/tongue.gif...ran into a couple of other little things like: petcock on radiator doesn't work...just spins...I guess it's stripped...so off to the shed. By the way, those tower clamps are a pain in the ***....once there on for awhile they are tough to loosen up. Got as far as putting the 5 blade fan back on....next trip I'll try to button it up and then on to cleaning the disc brake hardware and more detailing.

http://www.yenko.net/attachments/311383-tn_DSCN0980.JPG

[WILMASBOYL78]

another..need those w/pump fittings

http://www.yenko.net/attachments/311384-tn_DSCN0981.JPG

[WILMASBOYL78]

and....the smog pump...this is the original pump from the car...never restored..it's really in great shape.


http://www.yenko.net/attachments/311385-tn_DSCN0982.JPG

[WILMASBOYL78]

and....original 837 going back in place. Does that self threading bolt look correct for the battery cable..??? also...does anyone know if this vintage Nova used the U shaped bracket to hold the heater hoses in place...I see it bolted to the alternator bracket in photos of other L78 engines.....can't locate my assembly book.

Is that exhaust manifold tapped for the smog tubes?

[WILMASBOYL78]

Yes it is...there are some flat head type pipe plugs in the holes...these are original dated manifolds from the car...they were in the trunk along with the smog pump when I bought it http://www.yenko.net/ubbthreads/images/graemlins/cool.gif http://www.yenko.net/ubbthreads/images/graemlins/cool.gif...now all I need is the plumbing.

Yep, cool car. I'd have a hard time deciding which one to steal from his shop: the Black '70 or the Orange Cooler! http://www.yenko.net/ubbthreads/images/graemlins/worship.gif

If it's a later model made in China.......chances are it won't work.............Besides, Those Nu Yawk cars drive with an Accent http://www.yenko.net/ubbthreads/images/graemlins/biggthumpup.gif.........So bringing one back home to the Midwest would be kind of hard.....Even in Roodhouse.....LOL

[Mr. Chevy]

Tom, the self threaded bolt looks correct for the negative cable. I believe they had the anchor on the head of them. I have also seen the negative cable bolted to the motor, pass. side. The assembly manual shows both ways but I think technically it bolts down on the motor for the big block. Also it should have the "U" shaped holder/bracket for the two heater hoses that bolts to the alt. bracket...

Car looks great!! Good luck at the NATS!! I would like to get my car there someday..

Rich, here is a photo showing the clamp...69 engine pic...i thought the 68-69 BBcars ahd the neg cable going to the block and the 70 went to the alternator bracket...


http://www.yenko.net/attachments/311441-tn_4b23_3.jpg

[Mr. Chevy]

Tom, I would have to double check the assembly manual. I remember there were pictures showing it both ways. Mine(70 car) is bolted to the alt. bracket just like you have yours. I don't have the assembly manual handy it is out in the garage. Tomorrow I can double check it. I'll bet Marlin knows for sure... Seems to me your right and I'm sure if I bolted mine to the alt. bracket I must have done so according to the assembly manual becuase I know I had it out when I was putting the alternator and my smog assembly back on the car..

Rich

[Mr. Chevy]

Tom, on page #306 of the 1970 Nova assembly manual it shows the negative battery cable ground being bolted to the passengers side front of the block rather than to the alt. bracket. This shows it for the V8 396 engines.. But on page #307 it shows this cable being bolted to the alt. bracket also for the v8 396 motors. Like I said I remembered it being shown both ways. I have seen it both ways on restored cars.. I guess either way is correct.. http://www.yenko.net/ubbthreads/images/graemlins/dunno.gif

Rich

[Mr70]

Look on the bottom of those pages for a revision date & notation Rich..
1970 Chevelle Big Blocks batteries started off being grounded at the block up until 10/31/69,then afterwards they received a special bolt/washer & cable to be attached at the upper Alt.Bkt.from then on.
Most of the 1970 BB vehicles got the new 1970 design upper Alt.Bkt. with the 3rd hole to accept this,but the assemblers continued to ground the Batts at the block,even though the Bkt. hole was there waiting for it.It took awhile for workers to understand it was now more time/cost effective & safer to start grounding these there.

[Mr. Chevy]

Thanks Rick, I figured it may have had something to do with the revisions but I could not figure out how to decipher it.. That makes sense...

Rich

[Mr. Chevy]

Tom, I like the windshield washer monitor fiber optic setup. I just noticed it looking at the pictures. I have one on my car they are neat!!

Rich

[WILMASBOYL78]

There is a small indicator light that mounts under the dash...near the e/brake handle...this was part of the auxillary lighting package I beleive...cool little unit.

wilma

[Nova Jed]

I saw one a couple of years ago at a dealership in Pa. How did that thing work? Did the light get brighter as the fluid went down?

[Mr70]

Basically A styrofoam float followed the level of the windshield washer fluid.
A paddle having a green & red lens on top of it would shift in front of a dimly lit bulb.When the level was low the color red would illuminate.When it was full,the color green would illuminate back into the sight lens mounted under the dash,notifying the driver of this.All this via a fiber optic line.
This option actually had 3 different designs,all varied on what time period throughout 1970 you received it in.
You could order it seperately as RPO CD-2,or with the Auxillary Lighting group as ZJ-9.

[Nova Jed]

Thanks for the info! I guess that wasn't too accurate on a bumpy road, but hey it was early technology. Cool. Just like the traction dispensing compound option that wasn't too popular on the Camaro's. I have only seen one of those units in a Camaro.

[Mr70]

That too was a http://www.yenko.net/ubbthreads/images/graemlins/cool.gif option.

Now back to Toms Nova..

[Nova Jed]

Looks like you are ready for the Winter like Tom is! http://www.yenko.net/ubbthreads/images/graemlins/biggthumpup.gif Nice display. Please forgive me Tom. It's still all about the Nova's.

[Mr. Chevy]

Jed, that windshield washer monitor light unit was a one year stint only for 1970. Chevy realized later that those things would freeze up in the winter time and the float assemblies would crack. I guess there were a lot of unhappy chevy owners who returned their cars to the dealerships after this happened for a warranty on the part so they scraped the idea for 1971..

Rich

[WILMASBOYL78]

Did a little more work on the winter project...took a few photos underneath..this is the original 418 starter.

Tommy, That is a great looking car!! Looks like you are taking care of business this winter. Bring this car to the shows. Leave those cookie cutter restored cars at home. They all look alike. This car got some personality!!! http://www.yenko.net/ubbthreads/images/graemlins/biggthumpup.gif

Thanks Sammy....it truly is a time capsule...planning on taking her down to FL for the Mini-Nats in Orlando. Got a few more things to do to get her ready...then off to the palm trees...

I loved seeing Joe Demesy's cars and the rest of those survivor L78's at Vettefest! That was my favorite section. Chris's black Camino was killer too! http://www.yenko.net/ubbthreads/images/graemlins/drool.gif http://www.yenko.net/ubbthreads/images/graemlins/3gears.gif

Had those bolts off today...wish I had known http://www.yenko.net/ubbthreads/images/graemlins/frown.gif I still have to work on the fan shroud and radiator install...maybe I can shoot some photos thru the rad support. I'll try...


wilma

[396L78canuck]

Thanks for the help.Can you also tell me the exact length for the radiator overflow rubber tube.Had my radiator rebuilt at legendary and they lost the original one.What the build date on your carb?.Your car was built very close to mine.My car was built in November 69 and is an automatic.I currently have a rebuilt 4492 dated 1st week of November 69.Iam wondering if this to close.Bob

[WILMASBOYL78]

Bob, What week in November was the car built...??? what is the assembly date on the engine..??? I won't be able to get those fan bolt pictures for a couple of days, will measure the hose then, too...tom

[396L78canuck]

Tom the engine assembly date for the engine off the protecto plate is 11/10 of 69 and the build date is 11D.The body number is 23532 and the car was sold thru Maurice Carter Chev Olds in Hamilton Ontario. Bob

[WILMASBOYL78]

Bob, that carb should be OK....all of these components were made in batches, that's why you see so many commn dates. I've seen a lot of BB carbs with Nov. and Dec. dates...does your car have the original CW coded trans..???


tom

[396L78canuck]

Yes the car still has the original transmission Cw and the original rear end along with the original block.Bob
