This morning I acquired another block for my '72 F100 project. Here are the casting marks on the block; D4TE, 105 and a date marking of 6A19. The crank is marked 2TA. I bought it as a 360, but after reading until I'm getting numb, I'm confused. Is it a 360 FE or a 361FT? I read one item about distributor size, which prompted the concern. There is a lower section of a distributor broken off in the block, like it was forced into the hole. I only needed a block and this had no heads or intake, so the broken aluminum housing stuck in the block is of concern. The crank snout measures 1.371". Considering my cheapo digital device, I'll accept that as 1 3/8".

Update; The broken distributor lower housing is soaking in Seafoam Penetrating fluid for the night. The more I looked at the problem, it looks like a dissimilar metal problem that has been sitting for quite some time.
The pistons are marked 360
The rods are C7TE-A
The 6A19, I have deciphered as the casting date of January 19, 1976

Thanks for any help.

I don't have a book handy but that snout diameter sounds like an FT crank to me..

 

FT = 1 3/4", FE = 1 3/8" crank snout.

 

Thanks 85! I'm getting more confident it's an FE block, the more I read. I've had so much bad luck finding a good block lately, I am gun shy. Two blocks were cracked when magna fluxed and the short supply of good truck candidates is dwindling.

 

D4TE FT engine cast 6A19 = January (A) 19, 1976 (6).

 

Bill, I was hoping you would reply, thank you! I know there are a great deal of interchangeable parts, but here is where I'm trying to go. I have a number of aftermarket FE parts that I need to be sure they will fit an FT block.
I have a set of freshly rebuilt heads (D2TE-A), a Holley 390 Streetmaster intake and I'm was about to purchase a SCAT rotating assembly with FE main journals. Will these parts interchange?

 

The blocks are interchangeable. The distributor hole is the only thing different. And if you have an FE distributor, you can bush the FT hole to fit. And vice versa, you can drill the FE hole to fit an FT distributor. Everything else as far as the block goes is the same.

 

Thanks for the info Baddad! I'll have to post a picture of the broken housing and cam gear. The engine evidently died of oil starvation, as the main bearings are "heat blue" and into the copper. I'm really glad that all I needed was the block!!

 

Here's a picture of the broken distributor housing. I finally used a saw and made two cuts from the inside. Rolled the block over on the engine stand, used a long punch and hammer..........out it came.

 

All that work and it turned out to be another cracked block. The quest for a good 360 block continues!

 

That's the bad part of being up north. We get them too down here, lots of people ran just water in them, then they got parked for one reason or another and left them to the elements with the water in the block.

 

Today I'll be at the Ford Nationals in Carlisle, PA. It's 18 miles from my house and you can find every exotic part Ford ever made...............provided you have enough cash.........lots of cash. Beautiful cars and trucks too!

 

360/390 use the same block, the bore is the same (4.05"), the stroke is different.

Measure the stroke to verify engine size: 360 = 3.50" .. 390 = 3.78."

 

Re: the quest continues.

What I'm looking for is a good D3TE or D4TE in a F100 to F350 to use the block as the base for a stroker engine. My intentions are for the engine to have good torque from 1800 - 5000 rpms (Lunati has a good cam profile for that). The heart of the engine will be a Scat rotating assembly with a 4.125" stroke and a compression ratio of not greater than 9.8. This should give me a fun truck to drive around, with enough torque to tow my Thunderbird to shows of greater distances.
The desire for a D3 or D4TE block is the better webbing. The most recent cracked block was a "mirror 105" which I had high hopes would pass the magnaflux tests.

Other parts on the shelf awaiting a good block are: D2TE-A heads with all new valves, springs, guides and seals; Edelbrock 390 Streetmaster intake; Holley 670 CFM Avenger carb and a set of Doug's full length coated stainless steel headers.
Rome wasn't built in a day, but I sure would like to get all these parts together soon. I'm sure some young guy will look under the hood and say, "Ugh, it's just another old FE boat anchor"!!

The reverse mirror 105 replaced the 352 that was cast on previous blocks. That 352 caused all sorts of confusion because peeps thought it was the engine size. (sigh).
