Another F6
Well, not really. For those that may remember, or even care, about the F6 and F8 I've been trying to get from my uncle's place, I got the F6 moved today. That's the one buried in the woods. ( the picture I had posted on here before) With an airtank, we aired up the front tire, hooked up the skidder, and drug it out to the sawmill area of his cow pasture. It got one step closer to home, anyway. If things turn around, I hope to get it trailered next year. And worry about the F8 at a later time. Also, this F6 has the 2 speed rear, 159" WB, and the flathead 8 was not original to the truck. What I wanted to bring up about it is this: it has EAB heads. I believe they are better heads overall. Question is, what were the EAB's originally put in? My other F6 has 8RT's, and my F1 has 8BA's.
With nothing for a bed, I wonder how much it weighs overall, as well.

I had thought (and this is fairly loose in the knowledge department)...but, I had thought that the 8BA heads were used on the 239s up to 1951, the 8RTs were from the 239s 1952and up. The EAB engine wasthe 239 used in the cars in 1952 and although it had the same bore and stroke as the other engines developed 110 (as opposed to 100) gross horsepower.
This is from looking at the shop manuals from the 49-51 (non supplimented) Truck Shop Manual, and the 1952 Ford Car Shop Manual. There is no mention of EAB heads in the 48-52 Ford Truck Chassis Parts Manual.
Just FYI, the 337s were listed as 8EQs

Curb weight of a 158" F-6 with a two speed rear and no bed is 4710#s if it's equipped with 7.50 x 20s, or 4815#s if it's got 8.25 x 20s.
I hope you stood far away when you aired them tires.

I think Julie is correct, EAB was ford 1952 and 1953 and had 7.2 compression heads vs the 6.8 on 8BA heads. (per vanpelts site) although I'm not sure if any engines that went into trucks in 52 53 would have EAB on them I assume that all the trucks got 8RT heads all the way up through 53??
My 52 F6 has 8RT heads and it has enough oil and crud on it to look original but you never know I guess.
The engine I once picked up from a guy who had one in a 53 f-600 had at some point been rebuilt and the rebuilder had ground off the 8RT or 8BA etc off the heads, (they looked mismatched, one had smooth casting finish the other was more rough?? ) then more recently I found another rebuilt 239 same thing with the numbers ground off the heads?? must have been a reason, but don't know what it was???)
Those EAB heads are at least somewhat desirable I believe because of the higher compression, and higher horespower as Julie notes.
congratulations on getting it moved one step closer.

My truck has EAB heads on it, and I can hardly keep the tires from smoking at every stoplight. They are just one notch below ArDun heads, and turn an ordinary flatty into a fire-breathing monster!
Well, seriously, it's like everyone says, they are the best flowing stock heads. The extra 10 HP is likely an advertising thing, but if you are building an engine with a Merc crank they are definitely the way to go.
Josh, rebuilders ground off the designations because people balked at having mismatched heads when they mix'n'matched parts.

Thanks all. Yeah, Stu, I was kneeling in front of the truck, and just reaching around enough to push the air chuck onto the stem. I'll be back up there the 21st, and will remeasure the wheel width for trailering. Looking it over, I figured it would weigh similar to an F1, except add 500 lbs for the rear axle, springs, and wheels; an extra 500 lbs for front bumper, wheels, and springs; and perhaps another 300 lbs in the middle for double layer frame, parking brake assembly, and shifters. Subtract 50 lbs for no driveshaft, radiator, and generator, lol. But I'll go with around 5000 lbs overall, so it should go on the 14,000 lb trailer at work, barring wheel width. I think my flatbed will look good on this one.

Have we not shared this with you? It gives track width and about whatever else you'll need. Stu

Lol, probably did, but I couldn't remember. Thanks again, Stu. It's quite obvious I'm suffering from information overload on too many projects.

Getting close to making the trip. Just wondering if anyone had any opinions on using an 18 foot trailer with 7000# axles (2 of'em). The parts truck was delivered on an 18 foot car trailer, but this wasn't no 300 mile trip.

I've pulled my 20' with same axles behind my F-250/460/ZF5speed/4.11 gear loaded with Marmon-Herringtons twice and it did fine. Probably similar weight given the extra in my front axle and transfer case. Once was even from Arizona through the mountains. Depending on what your tow vehicle is, you should do fine. Stu

Who knew an F6 would balance on an old snowmobile framed trailer for 8 miles. Nevertheless, the parts truck is gone, and he made it. I wish I had a camera. We come-alonged the trailer to the truck under the front half, and he picked the rear up with the wrecker, and balanced the truck on the trailer all the way, now mind you, the trailer wasn't hitched to anything.
