Ok, clutching at straws here.
Inline 300 6 cylinder, 1979 F250 4wd
Just R=R'd split manifold, (the bane of my life), new plugs, wires, cap/rotor.
Compression test was better than expected.
Starts good, idles good.
Can't get it over 45 mph in 4th, in fact it slows down.
When I let off the gas, it will give a small surge, but then dies out again.
It goes downhill ok.
I am wondering about timing?, Vacuum advance? Read that advance is taken care of by the ignition module?
My friend and companion for 28 years now.
Nobody knows Jack around here.
Any thoughts? Hep me please.
If I'm in the wrong part of the forum, please redirect me.

Sounds like a carb issue to me... How's the choke?
On a side note, what part of Idaho are you in? I've got an Econoline sitting in my driveway with a 300 that's going to get hauled off to a junkyard sometime here soon if I can't find someone to give it a good home or is willing to take it for parts...
Yahoo, I got it.
I was reading about setting the timing and I noticed that the vacuum line needs to be disconnected and plugged for setting the timing.
That totally changed everything. (It was like 5 degrees After TDC).
I was able to drive up Phantom Hill and actually had to slow down for the tourists ahead. Normally it's a crawl up.
Read the directions lol
BTW it's set 6 BTDC, now.
And I'm near Sun Valley, I would love to check out the econoline, but am getting tossed out of our trailer park by the new owners and haven't worked since November. So getting my vehicle dependable is top priority. I can live in the back of the truck till the snow gets deep. lol
Thanks for the info guys.
