motor mount bracket question

[blackmopar]

just picked up the truck about 2 weeks ago - the po swpped mtr and tranny to a 350/350 combo

I just realized the motor is leanin way to the driverside - brackets/mounts etc dont look bent/bad and no signs of frame crash - took pics tonight - these look different to me, and I am told they should be symettrical - are these two diferent mounts!?!?

Yes the frame mount on the passenger side should be the mirror image of the one on the drivers side. I've not seen one like what you have on the passenger side.....not sure what it's application is.....it could be a bracket for a 292, they were different.

thanks captain fab - any idea where i can get two new ones?

the back holes (frame) are the proper mounting holes for that eng. some move them forward for clearance for hei distr if it won't clear the firewall

Padre, I appreciate the response

Im assuming you are talking about the drvier side frame rail? I(think) the mount on that side is the one I need for both sides, from what I am being told - As it is right now, the engine leans towards the driverside and slightly back towards the firewall - so the psgr side is too tall and seems to be pushing that side of the engine towards the radiator - So I dont think ill be able to use the back holes on the driver side - though I dont have HEI

this link will show you the difference in the mounts
the d/side perch is the same for all applications. On the p/side the 292 perch is shorter and mounts ahead of the one on the other side.
v8's mounted rear holes; 230-250 I6's mounted in the frt holes originally
all that you have to get is the p/side from a 230-250 or from a 283 and it will all balance out

you are the MAN!! thanks a bunch Ron - now ot source it - Have only dfound the fancy tubular stuff like CPP and Performaance Online have, but pretty (and) pricey

I now know exactly what to search from your link
thanks again

Hey Guys
Ok so I have the new Psgr side mount and got both reinstalled (passenger is now on the 'outboard' set of holes of the framerail and the drivers side is now on the 'rear' set of holes - and the motor is ALIGNED/Centered in the e/bay - woohoo

Now the new problem - because of this adjustment to the motor I was able to move the tranny crossmember back to the oem holes in the framerail - PO just thought it was cool drilling new holes in the frame apparently - but now the trans mount doesnt align anywhere close to the center bolt holes on the crossmember - measuring from frame rail to frame rail the tranny tailshaft is centered - the mount seems too far to the psgr side

this truck had a powerglide - and got a th350 when po swapped motors - is there any difference in trans mounts for both trannys? Wondering if he reused a powerglide mount like he used the 292 I6 motor mount

Thanks for looking!

dang, so if im reading that right - there is no difference between the two for the mount
i wonder if the mount maybe deformed in the wrong location so now with everything aligned its missing the holes? It got to be an inch off alignment to the passenger side of the trans xmember holes

and as I say, framerails measure just about 28 3/4" wide and center of tailshaft is right about 14 1/4"

go back and loosen all the bolts on the frt eng mounts so that it is free to move a little. you didn't say how much difference that there is in the holes lining up. if you check the dimensions again you will find that there is 3/16" by measure plus the bolted up frt mounts. make sure that the holes in the mount are not offset at all and also check to see that the crossmember is noin backwards (the PO could have done that). if everything is in it's right place it should fall in place, though sometimes persuasion is a requirement.
sometimes it is even a tight exhaust system that can hold you up

3/16 here and 3/16 there add up to things not going together. It is always the little things that cause the problems. Just ask Joe's girl friend

Blackmopar, I see you are just up the road from me, I am in San Marcos!

Really appreciate the help here - the rubber mount holes are almost an inch too far to the passenger side of the xmember holes (really about the same distance as I moved the drivers side motor mount back - was on the front holes now on the rear holes as instructed)
How can you verify if the trans xmember is in backwards?

[blackmopar]

thinking i should get a new mount anyway to rule out any deformation - stupidly I didnt measure the center location of the trans tailshaft BEFORE I started the realignment, but it had to be angled towards the drivers rear tire

whats up neighbor! thats cool man. Yours on the road or project IM trying like hell to keep this one on the road but as you can see the PO aint makin that easy.
Nothing unfixable, jsut amazes me how some people put (or dont really0 put sh1t together!

[1964C10]

Hey if you need a hand give me a shout! Mine is a project, it is driveable but I don't feel safe in it with the original brakes up front. After I get my bed put back together I am going to focus on getting it into a better temporary driver. Yeah it is amazing how people put things together, I am rewiring mine completely because the harnes is so shot it's easier to start over.

So what does your truck look like?

as I stated prev, loosen off the bolts for the frt mounting(it won't take much there to make up an inch at the rear mount)
the exh can hold it over there also esp if it was put in with the eng at a tilt as it was before (you may have to disconnect it to totallly find out). It is sometimes a PITA to undue someone elses dream work esp.when they don't know a poop about it.

just measure the mounting holes and if they are in the centre side to side and front to back then you are fine, but if they are offset one way or the other, would it fit better if it was reversed????
now get to work and come back and tell us what worked

dig it - thanks for guidance - Im at work now, but should get to this tonight after football practice

Man, you are coming along nicely! and it's a long bed, sweeeet! Mine is too, I love it! Hey welcome to the board, this is a great place to learn.

[Captainfab]

The trans crossmember also has a slight angle to the surface that the mount sits on. It should angle up towards the engine.

makes sense, cool, appreciate the thought - got home late last night so didnt crawl back under - but hopefully in the next few days and Ill report back progress - realzie this prob aint rocket science, but all these tips help so I know any chevy and/or c10 specific stuff - sounds like its straightfwd - mostly wanted to make sure not a different mount/etc and crossmember backwards is comepltely possible given the other cool tricks the po did.

thanks again
