Ford V8 exhaust pipes for '42 CMP

[david moore]

Thanks for info so far.... but... the pics from Cletrac show, I think, that the crossover and "Y" are different than for civvy vehicles. Didn't the CMP's have a deeper sump/oil pan? Thus the crossover goes down deeper and the "Y" has a wider angle than those pictured in the various old Ford catalogues. So, all flat heads the same? Maybe not?

The codes in the military parts lists e.g CO11 etc. aren't matched in the civvy catalogues. There, the prefixes are quite different.

Another twist - aren't the CMP manifolds different than the civvy ones?

I wouldn't know where to start making my own pipes - but if anyone out there provides this service I'm open to quotes!

Still need help!!

From the S.E.-39-42 parts catalogue, the C011DF was the model for the F8.

From the Canadian Ford and Mercury Chassis Catalogue (1939-1944 Passenger Car, Truck and Bus) a part number of C016TF-2265A breaks down as:
C = Canadian design
0 = designed for 1940 model year (just the last digit of the year)
1 = 85 HP engine (2 = 60HP, 9 = 95HP)
6 = 176" wheelbase (1 = 101", 8 = 158", 4 = 194", not specified for 134") (interesting that CMPs were standard Ford wheelbases)
T = truck (A= passenger, B = bus, C= commercial, D= 3/4 ton, T = regular truck, U = dump, V = drop frame, W = C.O.E., Y = 1 ton)
F = right hand drive
2265 Basic part number and group (in this case the group is 2006-2449 brakes (service) and the part number is for "pipe, master cylinder to rear hose assembly)
A, B, C etc redesigned or changed part within the model year

This parts numbering system is only claimed to be valid 1938-1944.

On this system a F8 or C011DF should be a Canadian designed, 1940 model, 101" wheelbase, 3/4 ton capacity, right hand drive. It almost makes sense..... Except I thought all Ford CMPs were 95 HP and the 3/4 ton part and that might be the difference between 3/4 ton total capacity (including fuel, occupants, cargo, spare parts (anything not actually part of the truck), like the modern phrase "may be reduced by weight of occupants and optional equipment") and 8cwt useful load after allowing for driver, helper, fuel and other fluids, on vehicle kit etc.

I didn't see the C011DF prefix for the F8 in the exhaust section of the chassis parts catalogue.

Further to my last post David, you might find that your local muffler shop would be willing to fab you up what you require....
I have always found them to be quite reasonable on stuff like this as it takes the guys away from the usual day to day regularity...

The French used the Ford flat head until the '80's and then all the parts went to auction..There are tons of new old stock parts around..Get what ever you want from Red's..

Everyone should book mark this page ..It is a great source of information..
Even the Great Guru could learn a thing or too on his beloved Ford Blitz..

A word of warning, there are 2 different LH manifolds for this era Fords. they look the same but the exhaust outlets are in slightly different positions ( about 1 1/2 )as I found out when fitting the engine to my carrier.
I have been studyng Willanthey's F60L exhaust and it looks different to the truck type. It is tucked in very close to the sump in order to clear the front diff.

Hi

As a last resort for making a difficult to fit exhaust pipe or close tolerance header. Remember seeing and old hot rod trick of using the steel flex exhaust, noting unusual but the neat part of the trick was once the pipe was formed to the proper position the guy ran a welding bead down the side of the pipe. In this way the pipe was locked to the necessary shape and could be removed to be copied with a pipe bender.

Highly recommended by the Hot Rodders for fabricating system from scratch and not that far from you.

Good luck and keep us posted of your experience if you contact Dan.

Phil..
Us poor engine rats used flex pipe for everything from the manifold back..
And you didn't need to weld dickie doo...Once in place and tight the exhaust heat did the rest..you couldn't bend it to save your soul after it heated up..It was galvanized and the zinc oxide did the welding for you..
I remember having a rear hanger let go while I was performing in my '51 Ford for the ladies out side of high school and the whole muffler..rear flex pipe came stung out like a coiled wire fence when I ran over it and the weight of the muffler(Glasspack) and the spinning rear rubber did the rest..I had 200 yards of flex wire hanging off my left exhaust manifold..
I was the laughing stock of all the young ladies I was trying to impress..
But you are right..it was great stuff.

David,
I had the same dilemma when restoring my 1940 F8. I purchased a right side exhaust pipe from MAC's and my welder made some 11 cuts and 8 welds resulting in the attached. It took a number of fittings before it was finished! Works fine though!

Good luck!

Regards,
Jim Price

Jim, Thanks for your confirmation that this is a bit of a problem! When you say "right side" - do you mean the single cross over tube? Do you recall the Mac's code for the part you purchased? Did your guy fabricate the "Y" tube from scratch? How did you get the second flange?
Lots of questions but I'm going to have to go through the same performance one way or another!
I'll hopefully be down in Tucson for March - shame you didn't have a second set made and I could have brought it back in the car! No UPS cross border charge or Canadian 13% tax either!
Cheers
David
