Hi everyone.
I have to buy a fuel return line for the warm-up regulator on my 77 350SLC (yes, 350 imported from Germany)
I was able to find a rebuilt regulator (without the engine #), but now the dealer wants an engine number.
I tried cleaning the engine block on the passenger side in front of the engine mount but i see no signs of the engine number..
Is it in the backside of the engine mount?
How can i possibly get to it..?
do i have to crawl underneath the car with a flash light and degreaser?
is there any other place where i can find
this engine #

HELLLPPP!

The engine number on single cam V8s is behind the drivers side head (on the block). This makes it about six to seven inches below the top of the valve cover. It is stamped into a flat surface that extends rearward past the head.

If you stick your head in there with a little light it will be apparent straight down.

Steve:

Thank you.
I will try tomorrow again.
I was looking at the only part of the block i could see and get to with my hands, since the exhaust manifold gets in the way, it is nearly impossible to see the other side of the engine block (on the other side of the engine mount..)
I hope i have better luck tomorrow.
Thank again

Yuri,

The direction of view is from the top, straight down, from slightly inside the middle of the left valve cover over the rear between the engine and the firewall. Its tight but you can get one eye on it.
