Can somebody give me some measurements on the mounting the engine back 8" and down 1"? Sounds stupid. A measurement from the center crank bolt would be nice. Bolt to frame rail (Left and Right, unless it is centered) and relationship between crank snout and frame rail....up and down. Thanks

all depends on what frame you have. no rule on the motor having to be centered that I know of.

Oh crap, it is an 83 frame.

I have a 90's frame so I can't help :(

best bet is to go trolling for stock trucks to get measurments off of.

:beer:

That would probably work on the side to side. The up and down would be hard to measure cause the way the frame is, there is no relation after you move it back.

so what happened?! you just got the engine dangling in there?:laughing:
how different is your frame from mine?

Yep, its not different but when you move them back (lookin from the side of the frame) the snout is at a different relationship than in the stock position. It is in the top of the arch, fuck I dont know how to say it.

i get it...

prob not a huge deal.
measure where it is stock--snout to the floor.
then move back 8" and subtract 1" from ^^.lol

in other words......uuuuuuuuhhhhhhhhhhhhhhhhh..I dunno.
I would eyeball it and try to keep decent DS angles.

Cant be done...engine is hanging and old mounts are gone.

The frame drawings in the FAQ can help you some.

Tomorrow, I can see if I can get a level on my frame, underneath my xtra cab, my truck is an 83 longbed. I have an 85 22RE with 85 motor mounts, which I don't think would affect t he height (but makes it a PITA to mount on the 83 frame....).

Basically I just need someone with an Ftoy (on a 1st gen frame and motor moved back 8") to tell me if the crank snout is centered in between the frame rails. Or if not how far left or right. And to tell me how far the center bolt in crank snout is below the frame or even or whatever it may be.

I have an 82 frame with the stock engine mount "brackets" still attached. Will that help? I don't have an engine available to put in there for crank measurements.

Umm, probably not. I have two other trucks with no motors. It just changes everything when you move the motor back. I am sure somebody will post up that has an Ftoy done.

Take one of the stock trucks and measure from the existing mounts to one of those goofy square holes in the frame or some other bracket on the frame or something that still extists on your ftoy frame. Get the frame level then use a level and a square to get a "coordinance" from the reference point. Then use the level and square in reverse to pinpoint the old mount location on the ftoy frame. Then you can calculate where 8" back and 1" down is from there or whatever distance you want to change it. Maybe you already thought of this but decided it would be easier to ask somebody.:D

You probably won't get any better answer until Monday or later tonight as all the folks who watch this board that can answer this question are out at the Cougar Buttes comp.

Yeah I thought of that also, but all my other trucks are out in the pouring rain. I also "redid" my mounts that attach to the engine so that is gonna make it kinda difficult also, basically look like yours. Instead of welding the bushing tube directly to the stock engine side I coped it a bit. To be honest a measurement would be really nice.

I'm glad you are going through this so I know what to do on mine.:flipoff2:

x2 I also need some measurements on this. I have a 85' frame with all holes filled and mounts off. So not much to go off of but the frame.

Yeah that is my deal too SteelFuser....mine is all welded up too.

According to the frame drawings from the service manual, the stock engine mount position appears to be:

From the face of the front crossmember, the center of the engine mount (halfway between the two mount holes) is 19.8"

From the bottom of the frame (the low flat part in the center of the frame), to the center of the two mount holes on the engine mount is 7.45" up.

Those are the stock points, anyway, according to the FSM.

If you have a set of stock engine mounts, bolt them on your motor and you should be able to figure it out from there.

My stock mounts are all cut up. Just need an eyeball from an 1st gen Ftoy. "Um the center bolt in the crank looks about an inch below the top of the frame" and "yeah the center bolt is XX" from each side of the frame rail."

That is all I need.

Yes, but isn't the crank bolt position going to depend on that particular FToys mounting setup for their trans/t-case. Its going to move up/down based on how much the transfer case is dropped or raised.

Stock engine/trans placement is centered side/side.

Oh well, just trying to help.

left to right is where ever you want it to be. motor doesn't need to be centered.

Well as far as up and down I am nearly flat belly. I am running a FROR skid and just the part that goes over the front out put is the only thing hanging below the frame. I might tuck it up more though, but that will only make minimal difference. Now if I was hanging out at stock level vs. flat belly yeah that would probably make a huge difference. Good point.

why not finish the new tranny x-member tabs 8" back from the old ones and start by bolting that in. that will establish the 8" back you want. then eyeball something on MY block (w/stock mounts) like a freeze plug, engine mt bolt, or whatever and use a tape or the square and measure back 8" and down 1". Reference where ya end up on my frame and adjust your block (up and down) to land in the same spot.

dont make me come do it.

edit: since you are flatter belly than me, reference something nearest to the 'pivot' point (ie motor mount) on my frame.

I'm at 8" back and 5/8" down. I used the stock 84 motor mounts, and slid them back along the frame. As the arch went down there, it dropped 5/8". I did not want to cut the top plate off the motor mount, so didn't go the last 3/8". I went for dead flat belly with mc-07 dual cases (except the drain plug).

I'll get you my crank bolt height above the stock x-member tonight.

Thanks man! I thought about just sliding my stock ones back too cause it will naturally drop some like you said. I really did not want to fool with the headaches that plague stock mounts and NOW..............drum role please. 172:1:eek:

I used the engine side of the stock mount and coped into it about 3/4-1". Then layed some 1.75" tubing in there wide enough to use spring bushings. Then gonna make some tabs up from the frame. Basically like MtbrJon did....but I did mine and thought I had saved the world...then saw his!!

With it all mocked up the engine is kinda running downhill from the tranny/tcase. It puts it nearly flatbelly (cunt hair of the FROR skid hanging out) and a whopping 29 degrees on the rear yoke on the tcase!! I dont know if that is gonna fly or not.

Sorry I was a day later, Tex.

Front of front x-member to centerline of motor mount 26 7/8"

Front of front x-member to face of crank (crank itself...back of bolt) 19"

Centerline of crank at that 19" back position is 1 1/4" down from the top of the framerail. (this is motor 8" back and 5/8" down...it could go down another 3/8", or 1 5/8" down from top of framerail).

This is on an 84 4wd frame. Inside framerail to inside framerail is 22.5". Crank is centered exactly at 11.25" with stock motor mounts.

hope this helps!

Shawn

Thanks Shawn. I got everything mocked up where it "looks" right. I am gonna go do some measuring and see how close I am to those numbers.
