Hey everyone, i am new to this forum starting today. I have a 1976 Ford Maverick with the inline six 250 cid with a C4 automatic Transmission and stock 8.8 inch rear end. I am currently building a 302 from a 1969 engine block. I was wondering if anyone here has done this swap before and could give me a few pointers on it. Would i have to modify the engine mounts, as in grinding and welding to a new location, or do they sell a set of engine mounts that will go to the same location as the 250 and match up?

Thanks!

There are 302 mounts, not sure of the placement, but they are different and probably located in a different place. Nice Maverick. What app did you use to make that image?

Here's a link to some additional info. The V8 frame stands are needed and can be bought new from Crite's and Autokrafters I believe. Since you have a 250 the bell housing is the same between it and the 302. You can use your current trans with a flywheel to match the 302. The V8's had a belly bar between the frame rails and double hump trans cross member. The throttle cable is different and I believe you'll need different linkage for the column shift, but don't quote me on that.

I did a HD shot at 800iso, then 1600iso, then 400iso. I put them into Corel Aftershot Pro 2 and did a HD merge. Then used Pixeluvo for the final adjustments.

Thanks for the link I will check it out. I did hear that it was possible to get mounts that will just go over the frame supports where the 250 mounts are. They did suggest the bar for the engine, and of course the double hump transmission bar for the dual exhaust. As for the column shift, I plan on going to the floor with that.

If it looks like a Ford 9" with a third member that bolts in from the front, it's probably an 8 inch. Very common on Mavericks, looks like this one from a 75 Maverick 250 C4:
8 inch 5 lug 3.00.jpg
Most Maverick/Comet 8" came with 2 common gear ratios: 2.79 for cars with no A/C and no P/S, and 3.00:1 for cars with the options.

9" were pretty rare in Mavericks, I think exclusively with V8 cars, but I'm not sure. I think a Maverick Grabber or Comet GT still had 8" rear if it had the 250 and not the 302.
If it is a 9", it probably has been swapped out in the past from an 8".
The way to tell the difference between a 9" and an 8" is to look for the flat spot on the top of the housing. If the diff and the 3rd member are completely round, it's a 9"
if it has a flat section then it's an 8". Here they are side by side, 8 on the right: 9 in vs 8 in.jpg

The 2 other very common Ford rear ends have sheet metal covers on the back and look a lot like a Dana or GM rear end. They are the 7.5 used in pre-66 Falcons and Comets. And in the 70's they came back in 4 cyl. Mustang II's, Pintos, and Bobcats. very light duty. These may be found in other, older model, very light duty, applications.

The 8.8's are on later 80's model and up (modern) Mustangs, Thunderbirds, and Rangers, Explorers, Mark VII
Here's a pic of the 8.8 on the left next to the older, smaller 7.5 on the right.:

55crownvic- those V-8 mounts you have, are they Maverick specific or for any intermediate, like Falcons, Fairlanes?

He has them posted over on the Maverick Comet Forum and they were factory V8 Maverick mounts.

The Mavericks and Comets never came with a 9" from the factory. They all had 8" accept, I believe the very first 70 model cars built in late 69. Those got the smaller 7.5" 4 lug rears.

You can get the 9" from a Granada, Monarch or Lincoln Versaiiles that will swap right in as they could be bought with a 9". -Matt

If you can find a Lincoln Versailles to use as a parts car, buy it if you can. not only did they have 9", they also had factory disc brakes and they are a direct bolt in upgrade for a Maverick without any mods or fab work. They also had 351's and every option available installed.

But they are a very rare version of the 64/65Falcon/Comet 70-77 Maverick/Comet and 75-80 Granada/Monarch/Versailles chassis.
They are not identical, but share so much in common its ridiculous.

much closer than a Maverick to a Mustang.

produced in small numbers for only a few years

not very collectible

not a significant enthusiast/owner base like most other body styles of old Fords
