99t???

[Ol' Ron]

I have an engine that was presented to me as a 99T, recently rebuilt with no oil pressure. The engine has been in storage for 405 years. Yesterday I pulled it out to fix and sell. These are my observations:

Raized intake, 21A rods, No freeze plugs in the pan rail, and "A" heads. There is no markings on the heads or block of any kind. Bore is 3.197"

Could be a 41 Ford block bored with all the truck "Stuff" on it.?

What is the center water passage configuration in the block? Both of my blocks have this pattern from the top down: triangular, round and trapezoidal.

Hey Ron, let us know if the plug behind the cam gear is left out. Walt

Well, no core plugs in the pan rails is '41 and newer ... we know that for certain. We also know the raised intake surface is '41 and newer. The bore is stock (+oversize bore) 1941. "A" heads are mid '39 through '41. Of course the 21A rods are '42.

Without looking at it, I'd say you have the 'normal' 1941 Ford block, maybe late or early '42 with some 'truck stuff' perhaps.
A true and complete 99T engine should have 99T heads. There is a large "T" cast upon them vs. the common "A".

Haven't removed the heads yet. I talked to the former owner and he said he sent the block that was in the truck out for rebuild and this is what he got back. He doesn't think it was replaced because it looks the same??
I have a super duper oil leak system hooked up but had to come in to watch the race.

This sounds like WW-II blocks that Carprnter found in India. He had loads of brand new truck heads but said they only used these heads to ship the engines and I don't remember it was over 30 years ago but if I recall them saying people didn't like them. I ground what I think was the 99T off and the heads and it has over 108,000 miles, didn't burn a drop oil in a recent 1,250 mile trip in two days at 65 to 75 MPH. 11 straight hours the first day and 8 hours the second day. Has had Castrol 20/60 in it since original start up and didn't burn a drop of oil or use a drop of water on the entire trip in over 90 degree temperatures. I did use close to a pint of MMO through the top lube injector on each day.
Contact Harvey at Dennis Carprenter he was there when I bought it and is still there. G.M.

"Raised" manifold pad is '41-2 or wartime. I think engines with the extra rear raised pad for full flow oil line are wartime versions, as many wartime engines had full flow filters or coolers. Water holes in center vertical row will tell if originally 239 or 221.

Whilst on the subject of full flow oil systems in 99 blocks, here is a section from a WWII Canadian military manual explaining the way the 'Full-Flow' system operates.

After careful examination of this document it appears, to me, that if the 'bushing' is not removed from the oil gallery in the rear of the motor and the 'Full-Flow' oil filter holes in the block are plugged (as I have found is often the case) then insufficient lubrication will be the result. This is because the only path for oil into the motor is via the line feeding the rear main of the crankshaft. This means that the only oil path to the rest of the engine is via the crankshaft. Not at all an ideal situation.

I have a 99 block engine that had premature failure of the front rod bearings. This I surmise is for the above reason, but I have not yet had the chance to confirm this. I will post when I get the chance to find out for sure.
