motor mount question
OK, please someone help me here. I have a 76 4X4 f100 with a 360. I just bought this and when I did the flywheel was broken. So while I had to pull out the transmission to replace the flywheel I decided to swap the transfer case for a 205 and replace all the belts, hoses, etc. When I looked at the motor mounts I noticed that someone had fabbed up some steel plates with 4 holes drilled in them to mount the motor mount pads. I didn't think this looked right so I went to the parts store and bought some new pads thinking they would bolt straight to the block, but the holes don't line up. Is there supposed to be some sort of manufactured plate there that goes between the block and the motor mount pads or what? I don't want to put this back together like this if it isn't right. Pictures would help alot.
Thanks.
Thanks.

Ya, sounds like someone might have changed something along the way.
There isn't anything special about the original motor mounts, two bolts to block and then the stud into frame mount.
The real early FE's had only two bolts on block, then later they made them 4 bolt(I suppose so they fit more vehicles), and sounds like they used all four in this homemade set up?
The mounts are LEFT and RIGHT, so make sure you didn't have them reversed, as then the bolts wouldn't line up on block.

I have made plates like use are talking about when I put a pre 65 FE in a 66 F100, The older blocks did not have the same mounting holes on the block and we made the plates to ba able to use the stock mounts.

well my block has 2 holes on each side of the block like this : but they are spaced closer together than the holes on the pads. So, the plates have two holes close together to mount to the block and off to the side 2 holes spread further apart to mount to the pad. So I guess it's possible or probable that this engine came from another truck?

Wonder if an early 60's F100 mount would work? Should be the other pattern, but not sure how compatible the rest of it is? How well it would line up with frame mount?
I made a plate for my '69 back when I put the '62 406 block in it. Had the same problem.

I guess the other problem with this being an older block is I have no idea what displacement it is. I was assuming 360 because that was what came stock according to the VIN. When I bought it I didn't know any better and was told it had a 460 swapped in. I didn't learn until later that it was an FE block and could not therefore be a 460.
Seems like every time i go to do something right on this truck I find more garbage from previous owners. I do appreciate the help I have received here though.

Well, you could check the date code on the block...though we know it's an early one anyway. The heads will have date codes also, but won't tell you CI, as they could be from anything. The only way to confirm actual "size" is checking stroke. Using a piece of coat hanger thru plug hole...check the difference between top and bottom of stroke. It should get it close enough to determine.

The early F100/350 FE blocks use the same motor mounts (rubber insulators) as the later blocks do with TWO Exceptions.
Exception #1
1974 (after serial # U00,001) & 1975/76 F150/350's (note: F150, not F100) with ** 390 ** engines ONLY use the SAME motor mount on the right/left side > >
> > D4TZ6038A
================================================== ================================================== =========
ALL the rest (Exception #2 1965/66's with 4WD) use: C7TZ6038H .. Right Side / C7TZ6038J .. Left Side
All these motor mounts are OBSOLETE.
I searched the internet, found 10-C7TZ-H's / 3-C7TZ-J's / 5-D4TZ-A's at greensalescompany.com = 800-543-4959
Some Ford dealers still have C7TZ-H's and D4TZ-A's, but no C7TZ-J's.

ok so it looks like the heads are stamped c1ae and 3090-A. The intake has 5d28 and c5ae9425c. the block is real hard to read, but I think it says c3ae and 3010-h.
searching now to see what they mean, since I dunno.

also, i measured the stroke and it is 3 3/4", so it's definitely not a 360. I guess pulling the heads and measuring the bore is the only way to find out more? I see the c1ae on the heads means it was in a car and the casting is from 1961, and the block from 63.

the block is real hard to read, but I think it says c3ae and 3010-h. 6010-bare block part number, you sure it isn't 6015? 6015-Bare block casting number.
3000 isn't correct, cuz 3000 is the steering/front end group, 6000 is the engine group.

The heads were cast in 1961 (C1 = 1961), the block in 1963 (C3-1963) the intake was cast in 1965 (C5-1965).
C5AE 4V intake manifold: 1965/67 Galaxies w/352/390's used the same one.
No 360 ever was offered with a 4V, and F100/350's with 390's didn't offer a 4V till 1974 (1974/76: VIN engine code M).
None of those numbers you posted sez diddly about the engine size, because casting numbers cannot be cross referenced to part numbers.
No 360 engines till 1968, but 352's share the same stroke: 3.50 inches.
My guess. You have a 1963/64 390 engine out of a Ford Galaxie/Mercury or T-Bird.
Can't be from 1965 or later, because cars/trucks used the same engine block.
The same truck motor mounts from 1965 were used thru 1976, except where I noted ('65/66 4WD--1974/76 390) in a previous post
