When did 302/5.0 motor mounts change?

dotcentral · Post by **dotcentral** » August 14, 2009, 4:03 pm

Well, this caught me completly by suprise. I wanted to install the 5.0 into my 66 today, went with my motor mounts over to the block, and suprise! There are no provisions in this 91 T-bird block to accept the older type motor mounts. How are people mounting these in the older vehicles? Is there a way to do it without re-engineering the whole thing, or am I stuck with an engine I can't use?

They never changed the 302 block as far as motor mounts, 2 vertical bolts about 7 inches apart. The mount you have has to be something other than a 302. Pics would help.

Well, I guess I have an oddball then.

I fixed the link. The site crashed on me and I couldn't get back on it for about 30 minutes or so.

Those look different than the mounts on my 71, which has a 351W. the mounts on it look like, and I think can interchange with, the FE versions. I'll try to get some pics of it tomorrow so you can see what I'm talking about.

But I guess I'll hit NAPA up for a set like yours. What year truck did that come out of?

I have a set of mounts from a 91 Tbird and a bunch of 302/5.0 blocks I will take some pictures in the AM and post. I used the Tbird engine in my 86 Bronco with no problems. The Tbird mounts are different but bolt up to the block the same as all winsor blocks and the M blocks.

Mike, I'd appreciate that.

The t-bird had mounts that are sort of "D" shaped 1/8" thick metal plates, and have a hole in them. No way this would work with the engine stands in my truck. I'll try to post a photo tomorrow.

If I could get a mount that would fit the towers, that would solve my problems, I think and hope. An application or a part number would be very helpful. And size of bolts to attach the mounts to the body would help. I seem to have lost most of those.

So there's not a threaded bolt hole here? (see arrow)

If you look up the tbird mounts I think what he has are the hydraulic mounts. They are cylinder shaped with a stud on the top and bottom. There is a plate bolted to the block for the mount to attatch to. Sounds like you just need to remove the plates on the block and install some mounts for a truck. 1969 to 1985 year model F100/150/250 if my research is correct.

Yeah those t-bird mounts are special made and they are proud of them too....If I remember correctly they run about 80 bucks a piece...I had to buy 2 of them when I did the V6 to V8 swap in the other '93 I had.

Were you trying to use 352 mounts? No way they will work. Like others suggested you need 302 mounts for a 1969-1979 truck. You alos need the 302 truck frame stands, the 352 stands are about 1" higher and will cause problems with driveline angle and other issues.

Check out this page from LMC, you can see the diiferent 302 and FE mounts.

I thought the FE and small block were interchangeable, but I guess not. The mounts on my 351W sure look similar to the FE.

Anyhow, thanks for setting me straight. I'll have to buy a new set from the parts store.

289, 302, 5.0, 351W, 351C all had same bolt provisions on th block. The rubber mount is different for TBird and Mustang and F-100.
