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

Pretty simple but works. Chuck in NHThat may be something worthwhile for a small fabricator to reproduce. Hoosier Hurricane pointed out that the original Hurst mounts were probably made for 239s. Result was a little interference with lower radiator hose, and major interference with later 272/312 fuel pumps, necessitating electric pump. If you want to sell your Hurst mount I might be interested to have a spare. I have the Hurst front mount and a rear mount for '46 trans. There is an aluminum transmission adapter from the 60's in between. The distance factor from front to rear was always a concern, so did everything possible to lighten weight between the two (but no Mummerts heads yet). Truck is fairly light at 2800 lbs., nice 292, currently 2V carb, and no problems.

Awesome.. Thank you all for the info. With the T-bird and the hurst mounts being similar to what I plan to do, I think I'm going to give it a shot.
If it gives me any issues, I might make a couple of support brackets that fit up to the bell housing. I'm thinking of something that looks like a engine plate, but a bit more discrete.
Thanks again!
everyone likes a picture, so here's the car that getting the 292... enjoy!

In re: bolt grades, I had noticed that Ford always used 'grade 2' bolts to bolt a bellhousing to a block or a transmission to a bellhousing. I had always assumed that this was because they expected some 'flexing' of the assembly and that grade 5 or grade 8 bolts simply wouldn't last in that environment.
There are case studies showing that grade 8 bolts won't last in certain circumstances where a grade 2 bolt lives quite happily.
Just saying.

I plan to use the Hurst mount in my 28 Chrysler so it isn't for sale. I would be glad to share the dimensions or even loan it to a fabricator that wanted to reproduce them. Not sure if there were any inherent problems with them. I've never used one. Seems the best mount to allow the use of alternative exhaust on a hot rod. Chuck in NH

Chuck, the wide mount that he has is alot like the Hurst mount, and as much as I love a Y block, that roadster of yours is just screaming for a early hemi. Just my opinion!

Glen, I completly agree and maybe someday I'll find a deal on a decent early Hemi. But for now I have a complete, rebuilt, spare Y-Block. I'll put it in and enjoy the ride while I'm looking. Prices for the Hemi's is a bit steep for me. Maybe you could find a decent one for a cheap price someday? And maybe when you do I could find the money. Right now with Ted building an engine and other expenses it's out of reach. Chuck in NH

I didn't see it mentioned and sorry if it was but Flat-o makes a C-4 adaptor for the car and one for the truck with side mounts. http://www.flat-o.com/carproducts/yblock.htm. Mummert probably has them as well as the adaptors he sells are made by Flat-o.
Using the truck bell would allow you to use the truck front mount and support and stabilize the rear of the engine with the bell mount.

Another thing to think about with the front engine mount: Headers! Not sure if you have a set of headers figured out yet, but Ive heard that the truck y-block headers provide a better flow and a little more horsepower. I think there are a few companies that make after market truck-style headers for cheap. I have been tempted to buy a pair of these headers for my station wagon with a 312 y-block, but because the engine mounts are on the side of the block, not to mention suspension issues, the truck headers would never fit.
I imagine if you use the truck style mounts, you could get some efficient and cheap headers that would fit on your y-block! Just another thing to think about...

A Hurst mount is on Ebay.

The "Brick" uses the wide truck front mount and a tail shaft mount on a Toploader. We even run a little bit of power through it, never had a problem with it breaking in the middle.

By the way, I love that salty truck. - as far as headers are concerned.. I'm going to be running lakes style headers (open), just like my current 302.

Has anyone seen aftermarket engine to frame mounts to put a side mount 292 in a Model A frame? Or are they normally fabricated? This would be the engine, not prame mount. Thanks. RB

This would be the engine, not frame mount.A Ford FE (390/427/428) universal engine mount kit should be the same as what you’d use for a Y. That will give you another avenue to explore. Here’s a link to get you started. Speedway FE mount kit
