That 390 carb was meant for the 258 with 4bbl intake, the 2 bbl carb came in different cfm's depending on model. Like I said, it will work but will run out of steam very quickly.

Alternator wiring
Pic from the 1978 manual. wire 1 and 2 to the solenoid..
This is my alternator.
12red = bat (yellow plastik connecter is replaced now by soldering connector)
the connector aside with the blue connector is the 44 green to the voltage regulator
the green wire was the electric choke with about 6 V
have replaced them. Choke is now from 13A red when ignition is ON
is this ok?
(The oil pressure sender is renewed too and has now a thread for the connector)

Today i did my drive to the licencing office
about 10 km single distance.
at the return trip the exhaust becomes louder from the engine bay
Look at the sealing. I have this sealing new mounted!!
It is like rubber and total broken.
have bought 2 pieces, one for sparepart...
(have complained it by the dealer here in germany..)

Have bought a replacement fuel filter with the 3 hoses, one for the return to the tank.
what i have read ist the return tube on the top.
Than means the filter is horizontal mounted.
What is the original place to mount them?
With a clamp at the intake manifold or the steering pump holder?
or is the filter only inline the tube without a clamp?
a pic would be helpful..
thanks in advance!78 chief 360amc (sold)

Once you replaced it, you are good to go, right?
You have a license for it now? Did you hit freeway speeds yet? How was the drive (other than getting loud)?

There was no clamp to hold the fuel filter to the engine. It was only held on by the fuel lines.Chuck McTruck 71 J4000

I replaced it preventive conjoined i did a new gasket at the right side at the exhaust heat valve..
The new one is scrap made in india

Yep, Horizontal mounting. From the factory, there is a hard line that comes out the fuel pump, runs up between the water pump and power steering pump, along the manifold, the loops over to the fuel filter. The fuel filter usually sits right around the valve cover. the middle nipple then feeds the carb, and a soft line comes out the upper nipple and travels down the side of the engine to the hard line on the frame rail.
There was no clamp to hold the fuel filter to the engine. It was only held on by the fuel lines.
Yes it drives.
the kickdown works now
the steering is indirect. (for german cercumstances)
carb setting is not optimal.. from idle to throttle is a bog sometimes.

carburetor setting
Hi,
after my first drive about 2x10km it seems the carburettor is to rich.
Please lets talk about the cruise setting and take a look on my chart:
The number under the rod size is to compare the size of the circular area between rod and jet diameter as a indicator for lean or rich)
I have now a 625cmf Carter AFB with 95 MJ and 70x47 rod, the circular area is 130 (blue marking)
(The stock setting of the carb is same rod with 98 MJ)
A Edelbrock 1406 with stock setting 98MJ and 75x47 ihas a area of 125 (pink) - a little leaner.
If I go to a 75x47 rod with the 95MJ the cruise is 107 (orange), "much" leaner as the 125 and leaner than the Number 8 in the edelbrock Chart with 73x47 and 95MJ too. (gray)
What is your introduction for my further setting?
Thanks in advance!

Originally posted by wiley-moeracingSorry a little hard to see but if its running good with no bog, hiccups, or sputters while driving, drop the jet size 1 down and try again.
Have to fix the exhaust sealing first and Drive again.
I have new 92 MJ here but no smaler Size.
The secundaries Jets 92 too ?78 chief 360amc (sold)

Make sure you have the float level correct and is the choke fully off and adjusted correctly?
I think i have the float level and all other meassurements adjusted dainty as recommended
the engine is to rich. it smells of unburned fuel.
When cruising in the 3 gear and kick down there is no bog and the engine revs well (but i have no comparison)
from idle quick to full throttle there is a short bog..
Today bad starting in the morning...
Today i have got the 75x47 rods and installed them.
will try it the next days (Because i have the diffs open for inspection, new diff cover sealing ...)78 chief 360amc (sold)
