Fresh rebuilt 8BA Flathead

[decling]

Picked up my freshly rebuilt Flathead on Friday. Shout out to Wayne at Coyote Flatheads for a great job.


Mercury 4" stroke crank
.125 bore
Offenhouser pistons

Isky 88 cam
Holly 94 carbs
Edelbrock heads and intake

[19Fordy]

Looks like a keeper. Well done. CONGRATS.

I do LIKE the lifting straps and the bar!

[decling]

Thanks, I like it as it does not damage as a chain might. I purchased from Jerry Bickel Race Cars Inc for $139 +shipping.

What are you planning to put it in?

It is going in a 1938 ford pickup. The truck is just getting started with a long way to go. Working on a engine run stand now to put this on so I can run it every couple of weeks until truck is completed.

Unless you are going to run it under a load you may be doing more harm than good. Search this forum for more info.

That's beautiful. Love black coloured blocks with aluminum heads and intakes.

I often wonder what scale people use to choose the parts they use in their engines. For example why did you choose the Offenhauser pistons and Isky 88 cam for this build. As expensive as it is, these decisions have a big effect on the applicationof the engine.

Delightful !

I discussed what I wanted with the engine builder and he speced out the parts. I relied on his years of experience building flatheads.

Well I for one think the Isky 88 cam is great!!

Man, your engine is gorgeous. I also like the black. It appears to be an 8BA-type ('49-'53). If so, how is it going to breathe (relieve crankcase pressure) without the original road draft tube? Has it possibly been built with a PCV valve incorporated somehow? If that black piece at the rear of manifold is a vent, you must be planning on an electric fuel pump....? Welcome to FordBarn! DD

Engine looks great !
Beautiful job,,,,,hope it runs for a 100,000 miles .

Correct, it is a breather and I will be running an electric pump with a regulator.

[19Fordy]

Is that the oil filter at the rear of the driver side block?

[Krylon32]

Ol' Ron: Elaborate on your above statement please.

[decling]

Yes, the block was modified to pass the oil out through a filter and then back in. this will be mounted elsewhere once installed in the truck. It was just there to transport.

Ah.....Is that a Canadian block? DD

[decling]

I don't think so. I could be wrong. My first block was a complete Mercury engine, gave me the crank. The block was rusted from the inside out when pressure tested. This is the 3rd block that was all just a standard 8BA.



The builder drilled and tapped the furthest hole in then drilled and tapped to outer hole to 1/4 pipe. Then tapped the inside line to block the flow. The oil is then goes out the outer hole through the filter and back into the new drilled and tapped hole. If I remember correctly as i was told this filters almost all the oil from the pump before it goes into the engine, except for the rear main bearing. I may not have remembered correctly, but I think that is right.

Does your engine have a number, possibly in the pictured location, and beginning with a "C"? DD

[decling]

No "C". I can't get images to upload at the moment. I will try later.

The oil filtering system is one of the best and I use it on all my builds. AS for the pistons, I don't think Offenhauser has made them for quite a few years and were once made by Janns. i also had a set of 4 ring steel strut pistons that were 3 3/8X41/8 (296 ci). This engine was still running a few years ago when replaced by a blown 294ci engine. I'm not familiar with the Isky 88 cam. I was just thinking of the application, and was curioun about the pistons and where they came from.

Nice looking engine

[mfirth]

Knew a guy with a twin to that engine, including that intake setup. It was in a 50 coupe.
He said it was the best running 8BA he ever owned. Wish you well with it.

[Bored&Stroked]

Looks like you do not have any sort of crankcase breathing system in it? I don't see the stock road-draft tube setup and I don't see a PCV . . . does it have one?

If you don't have a custom PCV setup, then you effectively don't have ANY effective crankcase breathing system in the engine. While it will run fine, what it won't do is pull water vapor and combustion gasses out of the engine . . . which is not a good situation for the long term. If it was mine, I'd modify it for a PCV setup - or go back to the road-draft tube setup.

Not trying to cause you any drama (that is a very nice looking engine) - just making sure you know about the need/value of a properly setup crankcase breathing system. Ford modified the earlier 24 stud system in 49 - to the later road-draft tube setup. It was a better setup than the earlier integral pan road-draft breather in the earlier engines - but a lot of guys removed them as they can be a bit ugly. BUT - they have a very important purpose that should not be overlooked . . .

Best of luck . . .

As B&S said, you got to have a proper crankcase vent system or you will have the problems he stated, plus, oil leaks. Picture on left shows engine in my F-1 as bought. Picture on right shows as it is now, many miles later. Leak free and no fumes in cab.
