sick six

The 1941 Ford I got has a "G" series six cylinder engine. I wish it were
the V8, but this is what I ended up with. It starts instantly, has good
compression, is timed good, but it has no power on hills. It just lugs
down and I barely make it with out shifting to second where I am
turning high RPM to keep up speed without causing a trafic back up.
I am using an electric fuel pump which I mounted under the hood but
plan on moving it to near the gas tank. Do any one of you have an
idea of what I can do to get this engine to perform?
Thanks
 
These sixes were strong engines.Elect. pumps belong back by the tank not under hood. You could be starving for fuel. You may have other problems youl have to pin it down some what to figure out.Do some more fishing. ken ct.
 
as ken said the 6's were stout, they will run with the v/8's, something ford didnt want you to know, either you have to high a gear in the rear end, or the timing is slow, spark advance may not be working, timing gear is worn causing slow valve timing, dont every depend on the timing marks, most are way off, rotate the crank back and forth to see how far it moves before the dist rotor moves, should not be any play, advance the timing and see if that helps, keep advancing the timing till it pings on the hill, then back it off till it doesnt ping,check compression
 
A couple years ago I had one of these sixes in a 47 coupe with a columbia with 3:54 gears . That six seemed to have more torque than the V-8 , it pulled hills just fine at hiway speeds in overdrive. I would look at the fuel and make sure the weights are not stuck in the distributor advance mechanism. One other thing you might consider is the heat riser on the exhaust manifold,make sure its not stuck partly closed. I removed the flapper out of the one I had so I didnt have to worry about it sticking shut.
The "G" series six doesnt have any timing marks. The distributor is front mounted like the V-8s and needs to be strobed to set up properly.
 
Gentlmen, thanks for the advise. I have put on a new distributor, I have checked the heat riser. I am going to move the electric fuel pump to near the gas tank.
A while back I located TDC on cylinder #1 and made a pointer and a mark on the
damper. Because the distributor is located behind the fan I can't adjust it with
the engine rinning. When I have just moved it a bit the engine would not start.
With it where it is as indicated by the mark I made and verifying with a timing
light, it starts imediately. I do worry about the vacuum to the distributor. I have
a small hand operated vacuum pump and will try to see if applying vacuum to
the line that goes to the distributor has any affect. I ahve never been able
to cause the engine to ping, even though the brake on the distributor is backed
off. When I last checked the vacuum my meter read "late timing" so I think the
problem is associated with the vacuum to the distributor. It could be that the
mark on the gear on the cam shaft and crank shaft is not in alignment. That
is the last thing I will check if nothing else works. I hate to have to pull the
timing gear cover. I don't think the gear ratio of the rear is the problem but
I do not count that out.
Thans for all the advise

A "G" engine has a crab type dist. as far as i know.It has NO line going to the vac. brake. It takes vac. from a small hole on the back side of dist and must have a rubber seal and must stand slightly proud of the gasket surface to effect a good seal. I have new proper ones if you need. Consists of a brass rivit like piece and a rubber grommet to go around it. Its NOT an "O" ring. ken ct.
