Hello All,

I found this site from the HAMB, and I have a question that I think is better suited for this forum.

I’m replacing the 302 in my ’30 ford 5 window, with a ’57 292 from a f100.  I’m using the C4 adaptor from Mummerts. The y-block is a truck engine that is missing (not drilled) the side engine mounts.

My question is…

What is your opinion regarding the engine mounts? My current plan is to use only the truck engine mount in the front and standard C4 tail shaft style mount.  Is the distance between the engine mounts and the trans mount too far?  Should I make an additional mount at the bell housing?  Anyone have any experience with this?

Thanks in advance!

There is one problem I see. Most truck mounts use only one mounting point at the front. If you are using that mount, then you will need something to stabilize the engine. Otherwise it will kinda roll around. If you have one of the truck mounts that use two points up front then you'll probably be alright.

Are you sure it's not drilled for the side mounts? The holes get filled with crud over time and can look as if they aren't there.

Thanks for the response. The front mount that I have is the wide type, with the two biscuit mounts about 16" apart.  I'm not sure if there will be much "roll" of the engine... the width is about the same as if the mounts were on the side of the block, but they are also lower. 

What do you think about the stress on the bell housing and transmission if I don't support the middle?

I'm pretty sure the holes are not drilled, the engine is pretty clean, but I will take a closer look and poke around some more.

I had thought about using truck mounts on a 29 because it would work with the original design of the vehicle. 50's Ford trucks (and a lot of Ch*vy cars and trucks) used bellhousing mounts to stiffen the chassis at the firewall. In the case of the Ford F100 trucks, a single mount point under the front/center of the engine was the final mount. This type of chassis design allowed the frame rails to flex, making the frame part of the suspension. The front fenders were mounted with fiber welting to prevent the metal-to-metal chafing that would have happened with this sort of design.



I know the early Fords used a similar design; letting the frame rails flex and be part of the suspension. So mounting an engine with bellhousing mounts and a single, centered front mount would fit that design.



Having the side engine mounts on the bellhousing also allows the firewall to be used to resist the torque reaction of the engine.



That's my story and I'm sticking to it.

I have considered the same thing with my 292 and E4OD.



I don't think you would want to use a tail-shaft mount and an engine front mount because it would put too much force on the engine to transmission bolts...specifically the 2 lower-side bolts.

...and the tailshaft for that matter......





The "car-mounts" they completely support the engine and a fair amount of the total weight of the transmission. The tail shaft mount doesn't support all that much weight at all. Maybe 100lbs or less.



If you cannot use the bell-housing mounts.......you should probably use the side mounts.

Aren't T-birds supported only at the front of the engine and transmission, and stabilized with steady rests?

In my opinon you will be fine with the wide front mount and the C4 tailshaft mount. The Flat O Matic C4 adapter is very thick where it bolts up to the block, infact it adds almost an inch to the length over stock. I would use grade 8 bolts and maybe a dab of locktite. By the way I bought the doughnut mounts at CarQuest a couple years ago.

Yes, but the steady rests, the way you are supposed to set them up, do take some pressure off the long mounting points.

Look for a Hurst front mount. Simple frame to frame saddle and your tailshaft will be fine. They pop up on EBAY on occasion. I have one if someone would want measurements etc. to reproduce them. Pretty simple but works. Chuck in NH
