[64 inboard]

I recently purchased a 1964 Correct Craft inboard ski boat. It has an inline 6 ford motor(i think is a 63 vintage) and I have no idea what size it is? The intake looks like it is cast as part of the head. I have a low compression problem in one cylinder and before going any farther ,would like to find out a little more info.

The block has a casting # C3DE6015-E. The head looks like #D3DE-6090 AA. Can anyone help me with displacement? , and does it have solid or hydraulic lifters? Is there a way to set lifters with the engine cold,etc?
Any help is appreciated! Thanks!

The block serial indicates 1963 design code, the head is later (1973).

Is the intake manifold a part of the head casting, or is it removable?

The intake looks like its part of the head... could this motor have solid lifters? Is there any way to tell?
Thanks

Yes, it sounds like a 1963/64 Falcon motor. The lifters will be solid, then.

Cold clearances could be taken as 16 thou, intake and exhaust.

Hody 64 Inboard:

As for displacement, count the freeze plugs on the side of the block.
3 = 170
5 = 200

If, when the head was replaced, a composite gasket was used you lost a half a point of compression across the board, unless the head was milled to compensate for the thicker gasket.

Actually, (not to sound like a know-it-all) your engine most likely has hydraulic lifters. My '63 falcon has the same block & it has hydraulic lifters. However, your rocker arms (if they are the original) are adjustable. Most likely its a 170, though like David pointed out, make sure you count the freeze plugs.

Thanks for the input...Im still a little confused tho. I think its a 170ci motor. The block appears to have 3 freeze plugs on the opposite side of the distributor. Its hard to see the one in front , as the starter is in the way. (this is a marine set-up with the flywheel forward).

One of the manuals Im looking in says that early 63s used a solid lifter ,before changing to a hydraulic set up. Is there a way to tell how "early" this motor is?

Is there a physical difference in the looks from one valve train to the other? These rockers mount on a continuous shaft and have hollow adjusting screws on top of the pushrod.

The more I read ,the more confused I get The motors look pretty straight forward, but this is throwing me for a loop! Thanks Again! Steve

Howdy Steve:

It is within the realm of possibility that FoMoCo did something different with Marine engines. All the best references I have or have seen indicate that all automotive blocks through the C4XX casting were non-hydraulic. They also have a smaller hole/tap where the distributor enters the side of the block and the distributor is driven by a smaller, 1/4" driveshaft off of the oil pump. Sorry, I don't have immediate access to my data on the diameter of the small distributor hole or the larger.

There are solid lifter blocks with casting # C3XX and C4XX in early Fairlane 200s. Most references are in agreement that the 1st hydraulic lifter blocks appeared with the C5XX and 7 main bearings. Do you know how many main bearings your engine has?

The adjustible rockers were present on many C5XX hydraulic lifter blocks, simply because FoMoCo had a policy of using old parts before the new. It is refered too as their "Empty Bin" policy. All 144 - 150 engines use the shaft mounted rocker system.

Edwin- what is the casting number on your very unique block? With FoMoCo never say "Never" or "always"!

Enjoy the journey.

Adios, David

David, my block # is C3DE-6015-E. I have dropped the oil pan & there are only 4 mains, 3 freeze plugs on the side & the lifters are deffinately hydrualic. A few years ago I had to pull the head & for giggles I pilled one lifter & it was deffinately hydrualic (now watch, that was the only one :roll: ). I know a little of the history of the car & to my knowlege, this is the original engine. I also have a '61 170 & carefully comparing the blocks, you can see the oil gallery on the '63 block. I'd always thought that '63 was the year that ford at least started with hydrualic lifters in the 144/170. But then again, like you said, you never know with ford.
