Thanks Tony for the offer but i will just use mine as it will still operate with the other spade and the chances of finding one with the same date code as mine will be slim to none so i can live with what i have even though the proper spade is broken off.

Greg Roberts (novaresearchgroup) has the correct rivets so that you can change out your broken relay and attach a good one. Tool comes with it and process can be seen here .

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

Thanks Sam, Greg sent me that link last night.

8-70
8th week of 1970, or 8th day of 1970, or 8th month of 1970 [img]<<GRAEMLIN_URL>>/hmmm.gif[/img]
Tried a google search but could not come up with a clear awnser on how to date a timing cover. Maybe someone here knows the truth.
The Tab has &quot;A&quot; &quot;O&quot; &quot;R&quot; with lines

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

8-70 is the 8th week of 1970. I learned this with the help of Joe Smith as he has never seen one stamped higher than 52.

As far as the rivets go on 70 Chevelles, I have seen them with and without washers and riveted from both directions. There has not seemed to be any rhyme or reason to how they were done and in my findings it was not plant specific.

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

Motor Rebuilder got sick before the holidays so still no progress on the motor till the new year.
I sand blasted the crossmember and re painted it myself.
The Drive shaft was restored by the last owner and it looks great.
Did Schmelzer make the oil pick up for Chevrolet or is this an aftermarket piece?

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

Sorry to here that but keep up the good work. *Paul

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

Its been awhile since i updated this thread but the motor is now moving along towards its completion.

I dicussed many things with my rebuilder and he did mention to me that the motor was once rebuilt in its history of being a race car so this is the second rebuild for my original LS6.
Motor was at .030 over so we decided to go .060 over to clean it up.
Motor was also decked,cleaned and neaded a cam thrust repair.

As far as the heads went we hardened the exhaust seats,did a valve job and resurfaced the base of the heads.

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

The Crankshaft was balanced with the flywheel and damper.
Some mallory weights were added and one spot was drilled out for the balance.
Rods were press fit onto the pistons and weighed.
A new GM 10216339 Damper was installed to replace the old beat up original damper.

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

Freeze plugs now installed and motor given its first coat of paint.
Re-assembly starts today.
Every part will be brand new,
Only the Crankshaft and Rods are original parts.

The Lunati 20202 Camshaft along with its matching 73124K1LUN springs will be used. I had this set up running on a previous 454 and really liked it.
Solid lifters will be the Howards 91118 with direct lube oiling hole.

Was your deck stamping preserved?

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: mockingbird812</div><div class="ubbcode-body">Was your deck stamping preserved? </div></div>

Yes it was but the machinist did come very close to the numbers and letters but they all show.
I was not very pleased with how close he came but he said it was the best he can do.

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

Whew! That was close!!! Looking good!!!

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

Pistons,Cam,Timing chain and Damper installed.
Head assembly is next.

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

Yesterday i finally got the motor in the engine bay.
Should fire it up on Monday [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details

Spark plug wires and start up tommorrow.
Fingers crossed.

Just a real nice job on a real nice car!

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

Still waiting for my motor builder to come by and do a break in. Maybe Friday or Saturday [img]<<GRAEMLIN_URL>>/no.gif[/img] It sucks to wait.
In the meantime i hooked up the spark plug wires, filled the antifreeze, put in the oil and primed the oil pump shaft and hooked up the battery to see if everything was fine.
Car has been sitting for a few days and no leaks to be found underneath.
I hope all goes well when we turn that ignition on.
My patience is getting thin.
Here is a couple of photos with the motor ready to go and complete.
Not bad for a Canadian AY.
Next reply i will let everyone know how the break in went.

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

Finally Broke the engine in today.
Here is a link to a Youtube Video.

http://youtu.be/CwF3X3y6qcs

The video shows the car at 2000 Rpm at the 15 minute mark of the 20 minute break in, all good + no leaks to be found. The valves were adjusted one more time,spark plugs were all checked and are all clean. Exhaust is next and a tune up will be done after the exhaust is completed. The guy that appears in the video is Gus who re-built the motor.

Only have one problem as the carb will not keep idle, what do you guys think it is?
Maybe the idle circuit needs to be looked at or maybe a vacuum leak?
After i do the Exhaust i will check for vacuum leaks and if i can not find anything then i will take the carb off and have it checked.
The car is drivable but i have to keep the idle at about 1500 to 1800 Rpm so it does not shut off.

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

Who did the carb?

How many turns out are the idle trim screws on the primary metering block?

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

The thing sound's good. I would stop the playing around and send the carb to Eric of Vintage Musclecar Parts. He is the best.

Carb was done by Jeff Dotterer.
The guy that owned the car before me had it rebuilt by Jeff.
If i were to do it i would of sent it to you Eric.
If i can not get things figured out i may send it out to you.
I will call you if and when the time comes.

The motor rebuilder tried adjusting the idle trim screws but it did not really make a difference

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

This is an Eric job...

He'll find a dozen things wrong with it. If I told you who the previous owner of my Z bought the carb from and how many issues Eric found with it, you'd be baffled in utter disbelief.

Guys as soon as i get the exhaust all buttoned up the carb comes off and will be sent to Eric. [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]

Eric is the best!


Your Chevelle looks and sounds great!

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

Nice Danny, must be satisfying to hear her cime back to life again. You don't need no stinking exhaust on that car!!!!! [img]<<GRAEMLIN_URL>>/no.gif[/img] [img]<<GRAEMLIN_URL>>/beers.gif[/img]

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

The hood is back on and all lined up.
Triple checked everything and re-torqued some bolts.
Main gas line was Rubbing against the new Harmonic balancer Damper (this could of been a disaster while driving) [img]<<GRAEMLIN_URL>>/no.gif[/img] managed to bend the pipe with nice clearance wedging a thin piece of wood and using a long flat head screwdriver to give it the clearance.
It is so important to go over everything 2 to 3 times after a re-build as you may over look something.

Installed the rear Walker tail pipes/Inline Tube hangers and GM tips and the front has the down pipes from Pypes which are not a bad fit but i added Gasket donut flanges, hammered out a flat spot for a bit of clearance were it goes by the crossmember and cut the drivers side pipe to even out the length as that side comes about one foot to long. The mufflers will be the 1969 Chambered exhaust in the center. My brother in law is dropping off the car trailer and off to the muffler shop the car goes this week.
After the car returns from the muffler shop i will take off the Holley Carb and off to Eric it will go. [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]

Looking at the undercarriage keep in mind that this car has never had a frame off resto [img]<<GRAEMLIN_URL>>/naughty.gif[/img]

Nice, is the speedo cable clip that attaches to the bell housing original ?

DL </div></div>

No,
It is actually an original 1970 Chevelle Hose Retainer that has been modified to fit the bolt on the bell housing to act as a clip.
I put it there for more support for the speedo cable.
Good eye DL (the part does look like it belongs there though)
The other support clip on the floor is the Original.

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

Here is what an original speedo clip would look like.

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

Thanks for that photo Rick,
I need to get one of those,
For now i will modify that clip to look like that original one (no one will ever know) [img]<<GRAEMLIN_URL>>/naughty.gif[/img]

Thanks Rick, one of our Buick restorers had some made, but could not tell if they were different design then the Chevrolet design. Or if the Chevrolet ones were re poped ? I'll post a pic of one later off the car. The originals had a T on them.
