Driveline

Kustom cars doesnt come with clear spec sheets…
I have straightened some question marks already about the driveline,
but I still had questions.
The only fact I had was that my driveline was from a seventies Chevy Nova.
Quite generic information...so which one?!?!
Took another dive the other day in the ocean of internet.
This time I found the excellent webpage Nova Recource
But even when I have read there and visited the Youtube channel I missed a lot.
I sent a mail to the webpage and got the most amazing help.
Thanks Scott !!
Those people make me believe in the world again
Big words, but that kindness to strangers is something we need more of.
Scott guided me through the Nova jungle so now I have a clear view of my drivetrain.
My front half have 1975-79 Nova subframe, same components also are used by 1970-81 Camaro.
My rear axle is a 10 bolt 8,5” and all of this are the parts that you want.
So in this case I´m the lucky one.

Winters is here

First days of November 2019 I jacked up the Chevy.
Its so low in the rear and the suspension is so soft so I needed four jackstands.
Two to support the rear axle and two for the frame.

When in the air I wanted to be a little more familiar with it and what the specs are.

First I spotted a tab attached on of the 10 bolts on the Chevy axle.
The tap said stuff about limited slip...me like.
Limited Slip
Tried the old trick to verify and just rotate the wheel and the other side turned the same way.


Yep, definetly no open diff.


Another thing I saw was of course the 4” drop with blocks and the tiny bump stop.


I´m aiming towards 3” blocks and maybe 1” bump stops next season

I also did som wheel turnin´to and got 2,¾ revs on the prop shaft for one turn on the wheel
So it's a fair assumption that I have a 2,73 rear end.
