Aha!! My truck has an rv cam, so it all makes perfect sense. The rv carburetor opens the 2daries earlier to supply pulling power. Also, since the rv cam tends to reduce vacuum at idle, that would delay the throttle opening a bit.

btw, I have a slight problem with the carb at temps between 32 and about 40.
As u know, it's quite damp here in vancouver, so the carb tends to idle rough until it warms up fully (icing). The choke has been reset and the fast idle fixed up some, which sort of cures the problem, but I'm wondering if a heated 4bbl spacer is the trick. I have an open air cleaner, and ideally the stock a/c with a manifold intake valve would be the answer, but in the absence thereof, is there anything else I can do?

Would running methyl hydrate (gasline antifreeze) help to cure this problem?

Jon,
My '79 Truck Shop Manual lists the 370 CID and the 429 CID together. It refers to them as "Lima" engines with the same basic design and structure.
The 370 was available with either a two-barrel or four-barrel carburetor.
The 429 was only available with a four-barrel carb (4180).

The 370 has a 4.05" bore and a 3.59" stroke. The 429 is 4.36" X 3.59" Here is the manuals description of these engines:

"The cylinder block of these engines is gray iron with
extended cylinder barrels. The crankshaft has five main
bearings and is cast-nodular iron on the 2-V engines and
is forged steel on the 4-V engines. The pistons on these
engines are aluminum alloy tin plated and feature a cast-
iron top ring insert which is metalurgically bonded to the
aluminum."
"Induction hardened exhaust valve seats are employed
on the 370 2-V engines. All H.V. engines have hi-nickel
alloy exhaust valve seat inserts. All valve stems are
chrome plated. Sodium cooled exhaust valves are used on
the 4-V engines."

The manual indicates that these engines apply to the B-, F-, L-, and C-Series Trucks.

Maybe. I'll give him a call and invite him, if I heareth no objections thereto.

Marko,
No, your rv cam doesn't open the secondaries earlier. That is controled by the secondary diaphram spring (black, in your carb.). But what your rv cam does is lower the vacuum a *little* at idle and lower rpm, (which may *delay* the opening of the secondaries) but more importantly it opens your power valve to early. It may run great, but it is also running rich and that can have a big impact on your mpg.

What is your vacuum in "Hg idle and what is your idle rpm?

Marko,
You are correct that a closed air cleaner with a pre-heater on it will help your cold driveability problem (and it will also help your mpg), but I think that you can improve the situation by checking/adjusting the vacuum brake. I don't know if your carb has the internal vacuum brake or an external pull-off. By trying different combinations of choke adjustment and vacuum brake, you should be able to dial that carb in for your local environment.

So, do you figure I should change the powervalve to correspond with the recommended one? Maybe I will try that....

Wow. Where were you when I was first trying to set the thing up! Anyway, as I said in my other mail, shd I switch the power valve, and change the jets to set it up as the carb recommended (0-8***)?

I will check vacuum next week, no time left today.

I have actually been trying to find some Ford Rep's email address and see if we could get some input here, but I can't seem to locate it so I posted the idea here.

The two piece cap has a lot of space between the terminals, this helps to prevent crossfire etc... that can occur with a high energy ignition system. They are easy to locate (It's a stock replacement part).

Hey THANKS! I really appreciate the info. I can actually aquire OEM Ford parts at a wholesale price (heh heh heh) so I shouldn't be paying too much for the ignition module.
I wasn't aware that Ford was still putting the FE into trucks when they started using elctronic ignition. I would actually prefer to use the Ford vs. the Aftermarket anyway.

Sorry No Fax, But don't worry I can locate the EWD in the later factory service manual.

I have a 1977 F100 with a 300 6 cylinder with a three on the tree. I am averaging around 13 - 15 mpg. I don't know if this is the general average or not. I would like to know what the average is for the 300. I tried to findout my rear end gear ratio, but the code I have listed (47) is not list in the Chilton's manual for my year. I have no idea what the ratio is.

Any Info would be helpful!

Not bad. I'm only getting 12 mpg from my '97 F-150 4x4 with the 5.4 liter engine. I got 15 on one tankful but that could have been a fluke. I'm hoping for something better after it breaks in a bit.

We run 460's on all of our delivery trucks and they get in the 8 to 9 range.....
