Flathead project

Looking at the earlier photos, I see that the engine has an internal coating of that special black protective substance (some call it sludge, but I think it's a flathead's way of protecting itself during longterm outside storage). Maybe there's even a Ford part number for it?

I think you need to get it off that motor stand ASAP. You may find it in the floor, if not now its a good chance when you start swinging a wrench on it. The rear of the blocks on the 48 and back cant stand the pressure.

Old Wives Tale !!!!
been building them for 40+ years on a stand like that !
Have 6 on stands at the moment !
 
haha 40 Deluxe, there was a lot of that black protective coating inside that motor too. Speaking of coating, I just pruchased POR-15 engine enamal for the block. I have read that some people use a base coat before using the engine enamal, if so what is the base coat???
 
Didn't want to take a chance putting the motor back onto the stand the way I first did. So I modified the stand to hold the motor by its exhaust ports. Per quickchange34s' advice, didn’t want to chance it. Then I added another caster wheel to it from 3 casters to 4 , for stability. See the pics .
Thanks

Just a reminder about supporting that engine....I've read plenty of horror stories here on The Barn about broken bell housings and smashed tootsies. That type of stand is not good for a flathead.
 
Nope. It's not Chevy orange....the engine is supported from the exhaust bolts...thanks for your advise.

I am pleased with Eastwoods work, I would go back if I ever decide to build another motor. They have a facebook page, check it out.
 
Nice work on the engine! I have the original 81A that was in my 38 Sedan. I hope to do something similar during some future Oregon Winter days. I currently have a rebuilt 1946 59 block in my car and it runs pretty nice. Nice pictures, thanks!
 
LS Juniper, I see the block is tapped and plugged with an extra plug above the oil sender boss (casting lump) Just be sure there is no plug blocking the cross drilling.(inside the horizontal drilling) It would stop oil flowing to your crankshaft.
The Canadian military engines were built like this for its 28,000 Bren carriers, because they ran an external oil cooler. The U.S. supplied engines for Australia's 8000 carriers as well as 1100 for New Zealand's carriers. (all of these were 239c.i.) Along with these many 221's were supplied to the U.K. All these engines had that extra drilling. I don't know how many were produced for local (U.S)applications in this configuration. There were obviously quite a few. The plus is, it allows the fitting of a near full flow filtering system, without serious mods.
Walt has a few clips on you tube about those drillings. Be careful.
 
Got a question, should I use the split type retainers on the valves, or should I go with the solid type? I put an isky cam in. It's the 77-b. I read that the split retainers can separate and do damage to the motor.....l don't want to mess this up....Thanks
