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 .

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.

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.

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?

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.
