Flathead project

[LSJUNIPER]

It was dipped in a hot tank about 3 times, 2 days per dip. Mark at Eastwoods auto said it was a dirty block. After the hot dip Mark pressure washed it. He then rough bored the cylinders .030 over.

Update, the motor is home from the machine shop, Eastwoods Auto Machine in Somersville CT. Took the advise of quickchange34 and mart and made a bracket to hold the motor from the exhaust ports...see pics...Thanks

I keep looking at the intake manifold surface on the block, Of all the pic I still cain't tell if it's a raised intake surface, in some of the pic it looks like it does. But, the engines with a raised surface were late 41-42 and had sleeves, so with no sleeves I'd call it a 39. Walt

[LSJUNIPER]

Walt, Yes it's a 39. Went to VanPelt sales webpage and I was able to figure it out by there section on how to ID a flathead motor....

I see the head studs have been removed. Did this present any problems? It seems like the hardest problem with the crusty blocks I have worked on.

I did try and remove the head studs myself, but they wouldn't budge. When the block was dipped into the cleaning tank the studs then were able to be removed. I had the machine shop remove them and two of them had to be drilled out.

Just a little warning - don't run a tap down the head stud holes - they are a tight thread and a tap will open them out. Use a thread restorer or an old stud or bolt with a slot cut in it.

If you already knew this I apologise, but it isn't obvious to a novice.

Mart.

Thanks Mart,

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?

[LSJUNIPER]

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???

[LSJUNIPER]

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

Kiwinus do you have a website for your shop? Sounds interesting.. This is my first Flathead.

[LSJUNIPER]

Some progress this weekend.
Painted the block and attached it to the motor stand.

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.

[Walt Dupont--Me.]

That paint better not be Chevy orange, if so it will never start say nothing about running. Walt

[LSJUNIPER]

Nope. It's not Chevy orange....the engine is supported from the exhaust bolts...thanks for your advise.

Starting to reassemble the motor!!

How was Eastwoods to deal with? I live nearby. I ended up taking my Flathead to Earl's in Stafford. Still waiting.

[LSJUNIPER]

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!
