Not sure how to phrase it...

A couple weeks ago I picked up a '78 cab and chassis with a Midas RV shell just for the engine and xmission.

Plan is to swap the 460 engine and C6 from the '78 into the '73 which has a 360 with a C6.

2WD both.

The question that came up last night was differing frame widths and how that may affect compatibility when looking at the towers and mounts.

I haven't measured the frame widths yet to see if there's a difference, wondering if anyone here has done this swap and if there IS a difference, how you overcame it?

I'm under the impression that the towers in the '73 for the 360 are different than the towers that would've been used if the truck came with a 460 originally.

Is this something I should be concerned about, and if so, where could I find the correct towers and mounts for my year and frame width combination so I can move this 460 over?

I'm not so good at putting into words what my questions are, so if you have any questions of your own that would help clarify what I'm looking to do here please ask away and I'll answer the best I can!

A member here and I will be pulling the swap as soon as possible because the 360 is giving out on me and I need the truck up and running with minimal down-time so I'd like to have all these details worked out and ready for as snag-free a swap as possible.

Thanks fellas

 

460 mounts and stands are by themselves. 3 pieces per side of engine. Some people adapt FE mounts or buy adapted ones with mixed results. I bought a oem set off of the bay to avoid engine placement problems.

 

1973/79 F100/350 460 (2WD only):

D3TZ-6028-A Right & D3TZ-6029-A Left .. Engine Supports aka towers/stands/perches / Obsolete

D3TZ-6030-A Right & D3TZ-6031-A Left .. Engine Brackets, these bolt to the block, the rubber insulators bolt to these, then to the supports / Obsolete

2) D3TZ-6038-A .. Rubber Insulators / Obsolete

The rubber insulators can be bought from auto parts stores, the supports and the brackets from wherever they can be found. Passenger Car/Econoline 460 parts will NOT work!

The C6 used with the FE engine cannot be used with the 460.

 

You will need a setup like this:https://www.ebay.com/itm/OEM-Ford-Tr...pbg2cE&vxp=mtr

 

The frame widths are the same. Take the perches from the 78 and put them in the 73 this is your easiest option. Since Ford offered the 460 in 73 you might have the right hole already in the frame. Use the transmission mount from the 78 as well, but it might need to be moved a little.

 

Is the 78 cab & chassis an F-series truck or an E-series van? If it's an F-series it has the right mounts. If it's an E-series the mounts won't work. (see # 3)

 

Thanks fellas.

The '78 is an E series so I guess when I said "cab and chassis" I should've said "cutaway". Sorry about that.

The concern that I have is IF the frames do end up being different widths then the supports (towers, stands, perches thanks ND) that come with the 460 will have the wrong geometry to match my frame width.

Thanks for that ebay link, 'DB. I'll try to get a quick look at the '78 tomorrow and see if they look like the ones in that listing. I'm thinking 200 bucks is out of line with what I'd want to spend, but if I need 'em and don't have another line on 'em then that's the route I'll have to end up going.

'Falcoon, are you saying the xmission mount alone or the whole crossmember?

Thanks again guys, appreciate y'all.

 

The whole cross member, but I thought they were both pickups, not sure if they will interchange.
With the 460 being from an E series it probably has a rear sump oil pan,
where the pickup has a front sump, might be some clearance issues.

 

I used the same mounts (#4) to put a 429 into a 78 F-150. Bolted right in. Watch E-Bay or check junkyards.

Dang. Good intel, guys, thanks

 

Ok, circling back around. Life has a way of forcing us to hit the pause button doesn't it?

I'm again looking for a set of perches to put this 460 into my 2WD F250 which currently has the 360. So much time has passed that ebay link in post 4 is gone so I can't even copy and paste the wording to find what I'm looking for, lol

I've tried searching a few different ways and come up empty-handed.

Anyone here have a link, or a line on some, or even a set to sell?

 

Found these on e-bay.

Maybe someone with more knowledge can tell us if they are the right ones or not. I think they are but I run an FE in mine.

 

I have a set still on a 460 in my shop! will these do?

 

sorry thought you were looking for mounts and cups

 

There are 2 other sources of 460 mounts, Sanderson in California and L&L in Rowlet, Texas. The transmission out put shaft from the van may be different from the truck. Good luck, Hiram
