Questions we’ve been asked about motor mounts.

Dear Welder Series… Crown Vic motor mounts?

Dear Welder Series…
I am putting a 351m in a 2003 crown vic front suspension, any sugestions on motor mounts?

Dear Vern…
Vern, our Ford mounts are for blocks that have 2 vertical mounting holes on 7″ centers. If your block is like this, either kit will work well.

I hope this helps.

Dear Welder Series… LS engine mounts: ours or theirs

Here is your kit and the USA kit- just trying to see the price difference of $40.00 ($130.00 canadian for the US kit), plus the difference in extra tax ($20.00). They look about the same? Do you make yours there or bring in from USA?

Dear Welder Series… scrap motor mounts

Email conversation with a customer who is wondering whether our mounts are strong enough for his 600hp engine. Other customers with twin turbo big blocks say "yes".

Photo Sharing: Chevy motor mounts

Glenn sent these pics of his Chevy motor mount installation. Nice work, Glenn!

One great feature of these mounts is that the engine weight is supported by the mount, through the frame rail, instead of by the bolt going through the rubber insulator.

Dear Welder Series… SBC in a Stude?

Dear Welder Series…
I will be putting a chevy v8 350ci in my 1956 Studebaker very soon and will try to use the chevy mount and see if I can use the lower part of the mount and bolt it to the bracket that’s on the Studebaker frame to end up with a bolt on instead of a weld on mount system. What do you think? Has anyone done this?

Dear Dave…
Hi Dave, thanks for your note. I’m not familiar with the Studebaker engine mounts and I haven’t heard of anyone doing this. Maybe someone will see your question and have better information than I can provide?


Dear Welder Series… Rubber transmission mount with urethane engine mounts?

I've seen that you don't want to mix solid mounts with rubber mounts. For instance I have a rubber trans mount, so I wouldn't use solid motor mounts. Any idea how the urethane mounts would fit into the equation?

Dear Welder Series… 1952 Chevy pickup Mustang II kit?

Dear Welder Series…
Hi there. Just now found you guys on the web. I am garage building a 52 Chevy pickup. I’m interested in picking up your IFS set up and a good 4 link for the rear. I have the body of mine stripped off the chassis and am getting ready to send it to be blasted and have the chassis boxed. Can your IFS be bolted or welded in with the frame boxed or should I have your parts put in and then box it? Does your IFS kit come with the motor mounts as well or are they separate? I could also use a trans crossmember as well. I’m going with a 454cid and a 700R4.

Dear Zane…
Our Mustang II kit welds into a boxed frame, so you can go ahead with that. If you followed the instructions online, be aware that it will almost certainly be necessary to trim the top of the frame rail for upper arm cross shaft clearance. This can be done after boxing.

We have 2 types of motor mounts for your 454:


These would have to be trimmed to fit your frame (the way the boxing plates are installed will affect the frame width) and to put the engine at the height you want.

I’d suggest transmission crossmember 2115:

This adds strength to the frame and lets you drop the saddle without removing the exhaust.

Thanks for looking at Welder Series parts.

Dear Welder Series… 1946 Ford transmission mount questions.

Dear Welder Series…
I hate to ask because I’m afraid I may have missed it in the blogs but Im going to anyway. I have a 1946 ford coupe. I’m installing a 4.6l dohc and 4L70 transmission in. I am getting the motor mounts and I am considering the the tubular center section. The factory frame has some plating but with large holes in it. Do I need to cut away that plating and make it solid? Also I’m not sure what if any transmission mount plate combinations I would need to mount up the 4L70. It’s a drivetrain from a 1998 Lincoln Mark Viii. Thanks for the help.

Dear Tom…
Tom, I’m not familiar with the Lincoln transmission, but we are modifying our 205041 adapter plate so it will bolt to the Ford C4, C6, and AOD transmissions. Here is the product:

If the 4L70 is available for you to get the mounting hole centers, please send them to me.

Regarding the boxing plates, we left the factory boxing in place and filled any holes necessary to mount the crossmember and engine mounts.

Because your car’s floor has a bit of a driveshaft tunnel, our tubular center section will not work as nicely as it does in vehicles with a flat floor. Check out the installation info below to see if this is how you want to go.

Dear Welder Series… Ecotec motor mounts?

Dear Welder Series…
Hello, I was just going over your website (very good I might add).
I saw the pictures of an engine mounting plate for the Ecotec in one of your articles.
I am in the process of putting the Ecotec 2.4 into my 72 Jeep CJ5 and was wondering if you had any plans to produce the plates?

Dear Terry…
Thanks for writing, Terry. The Ecotec install was part of the NSRA giveaway car which Dave Tucci built, that DW helped with. We didn’t make the plate and don’t have any plans to (unless people keep asking us for it…). We do a fair bit of custom work, like preparing CAD drawings and cutting to customer’s sketches. If we can help with that, please let me know.

Thanks for your interest.

Dear Welder Series… Motor Mount Dimensions

Dear Welder Series…
Hello, I was looking at your SBC motor mount (shown here:)

and was wondering what are the dimensions of it. What I mean by dimensions is what is the widest it is when everything is mounted, like what is the widest frame rail will it fit.


Dear Martin…
Martin, there are 2 versions of the urethane mounts. One (#2149) would max out at 32″ from boxing plate to boxing plate. The other (#21496) would max out at 33-1/2″ boxing plate to boxing plate. These dimensions will be reduced if the engine is mounted higher in the frame rails because the frame brackets will be on an angle.

Thanks for looking at Welder Series parts.

Dear Welder Series… 4.6l in a ’65 Mustang?

Dear Welder Series…
I was wondering how long it typically took to receive the “Ford Motor Mounts, 4.6L/5.4L/Coyote, Urethane Insulated” kit that you have to offer on your site? My project car is up in Pennsylvania so I am not certain what I need at this time, but it looks like your kit might do the trick.

Just some background…  I am putting a 4.6l mod motor into a 65 mustang. In this setup, would the welded kit work properly to allow me to get the engine as far back towards the firewall as possible? Not sure how much leeway your kit provides for backwards/forwards positioning.


Dear Erik…
Erik, our 4.6l kit can be installed where ever you want it along the frame rails. Kits are normally in stock and would take about 3 days to get to you from our place.

Thanks for looking at Welder Series parts.

Dear Welder Series… Motor Mounts for ’56 Chevy Pickup?

Dear Welder Series…
I am emailing to find out if you have a Chevy V8 mount kit that will work in a 1956 Chevy pickup truck.


Dear Jase…
Jase, either of our Chev motor mount kits will work in your ’56. The frame brackets must be trimmed to put the engine at the height you want.
