1967 MG MGB GT "Maggie (GT From Hell)"
As an engineer, I have a lot of appreciation for the amount of design and test effort that goes into every single component of a mass produced car. Where years ago, I would have dismissed this effort and assumed I can always do a better job, I no longer jump to that conclusion.

So I was wondering if anyone has looked at using the stock ford 302 mounts when mounting their drive train? The idea would be to have a car with vibration and harshness similar to a factory install. Are they just too big or just too ugly for a hot rod?

Peter, I am in the last steps of the final design of the bolt on Ford V8 motor mounts for the MGB.
This mounts will be adjustable and bolt on, but could also be welded.

I will include a trans cross member. No headers.

The new mounts should be ready in the next 2 weeks, that is the goal. Mounts will be powder coated.
This mounts will not sag.

To answer your question.

The original Ford mount is big and with the small margin of space and clearances they do required some shimming in the future.

Peter, I support your logic of using OEM designed parts wherever possible. Having worked for a truck OEM for many years, I can attest to the fact that all critical component designs are subjected to some kind of testing or FEA analysis.
Trying to use those components in an application like ours will sometimes create headaches and compromises. My 302 engine mount components are from the early '60's 260/289 engines - the biggest challenge was adapting the left hand mount to accomodate the steering shaft - but it can be done and I have the piece of mind that the mounts are a well proven design.

My 302-powered Cortina uses stock early-Mustang mounts, and late-model trans mount, and they have worked perfectly for upwards of 17 years now. There are several styles of OEM engine mounts, but I'm not sure that these would fit between the frame rails of a B....it would be close.

Mine have a stud through them to stop them coming apart, which was (I believe) original to the Hi-Po cars.

I'm interested in these. Will the transmission cross member be transmission specific or universal? I'm strongly considering going with an automatic due to some injuries. I would like to use a 302/AOD swapped into a 1979 MGB.

Bill,

Are these designed to mate up to the existing MGB mounts (as on late model cars)? Or are the to replace the MGB mounts on the frame?

NO ! I would never used a solid mount. The ones I am using are poly.
This mount has worked in many applications and the newest is in our new V6 kit.

I used this mount in many of my projects. The other mount that works very nicely and it is commonly used is the Mopar engine mount.Used in hemis, trucks. sedans even the slant six cylinder.

There is also a hydraulic mount but expensive. Fluid fill mount, it gets harder with pressure weight. Very expensive

Lloyd Faust (Balloonfoot on here) and I had this discussion a week or so ago. He attended the Reno meet and had a chance to ride in a BOPR conversion that used a rubber biscuit type of mount rather than the OEM mounts and he said that he could feel noticible vibration through the car. He and I have done several similar conversions and we use the OEM mounts (for all the reasons stated above) and none of the cars had a noticible engine vibration.

Definitely use the OEM mounts if at all possible and construct brackets to the frame to carry them. My $0.02 (and Lloyd's as well)

In reply to a post by dtownsend Bill,

The mounts are totally new and nothing to adapt. They will insulate noise and vibration. Most of the vibration (appears to be) comes from the rear. Reason why GM used a weight on the trans to eliminate harmonic vibration. The same is done with the rear calipers.

There are different types of mounts, Biscuits type about 4 different types, different hardness.

The MGB has very little space for mounts, specially when the stock mounts are used. The stock mounts do sag in time and have to be shim. On a stock vehicle this is not a problem, in the MGB it is.

4 years ago we ( a friend and I) built one using the stock Ford mounts. 6 to 9 months later they had to be shim about 1/8" to keep the front of the pan from hitting the rack. This area only has about 1/8" clearance.

I made three sets one for my friends car, one for Rob F. did not used the factory mounts, he used Ted's front end etc.. another set for...no reason other than to have for reference. I can take some pictures of this mounts. This mounts have to be welded and used the Ford mount.

Pics would be good. I was just getting set to cut the existing mounts off the frame and fabricate some new mounts. AM interested to see what you have before I go to the trouble. Thanks.
