I was quite surprised the other day when I opened up the new carburetor
that Holley installed bowl vent baffles at the factory.
I also went from #70 primary jets to #68 jets.
I also got my bowl vent tube installed. These along with the bowl
vent baffle makes it a lot better when off road.
I also changed the break-in oil. I chose Valvoline VR1 full synthetic
racing oil. It contains 1350-1400 ppm zinc and 1250-1300 ppm phosphorus.
It has the highest zinc content of any other engine oil.
And the oil itself is Ford Blue.
I installed a tachometer yesterday and I'm going to install a
mechanical oil pressure gauge today.
After I got the tack installed I went into town for some prime rib at South China.
As always dinner was delicious and Ashley the server is definitely a sweetheart.
So I filled the gas tank up while I was in town and I got 11.6 mpg, best so far.
That's pretty good for one of these old Ford trucks.
We have 3 routes into town, the freeway, HWY 89 and a "frontage road"
that's dirt and parallels the freeway from Elsinore. The dirt road is nicer
than most paved roads. I can't remember what the seal it with but the
county does a real nice job taking car of it.
I took the frontage road into town twice. The speed limit is lower
than the other two routes and I'm sure that's why I got the better gas
mileage.
I took a section of the freeway home to check the rpm at different speeds
and. yep, its not a freeway truck.

60 mph - 2600 rpm
65 mph - 2800 rpm
70 mph - 3000 rpm
80 mph - 3400 rpm
In its current condition it has no business going 80 mph.

Probably didn't when it was new either.
