66 restomod

yenrab2 · 05-29-2001, 12:46 PM

I have a 66 coupe which I am about to start modifying. It has a inline 6 which is not original to the car and looks like what you see in '80's Fords. It also has a 3 speed manual transmision that needs rebuilding. I have purchased 2 source cars, an 87 Mustang with the turbo4 cyl. and the T5 transmision. The second car is an 83 Mercury Grand Marquie. It has a fuel injected 302 that runs real sweet.

Here is what I am considering doing.
1) use the T5 for the 66.
2) use the 302 for the 66 after rebuild.
3) use the source cars for power stearing and brakes.
4) use the source cars for disk brake change on front end.

Question:

The Merc has 5 bolts front and back. Should I use this as my source car for brakes and possible rear axel swap? The 87 Mustang has 4 bolts front and back, and may yield better handling suspension if I swap everything out?

What gotcha's should I watch out for with what I am trying to do?

Also, if anyone is interested in getting the 4 cyl turbo, I am selling it real reasonable. It should run clean, but it is hard to tell since the 87 needs a fuel pump.

Thanks

You're venturing into uncharted waters with the hopes of using the front suspension / rear ends from either of those 2 donar cars. Neither of those are bolt-in parts, and I believe that they are (at least the '87 Mustang is) front steer. Your '66 is rear steer. The rears are not bolt-in swaps by any means. I'm not saying it can't be done...What type of fab skills do you have? I'd say find a Granada donar, or find parts from your specific year car.

I need some info on your current motor to be able to direct you in the right direction when putting the T-5 behind the I6. What is the casting number on the block (just under the exhaust flange), and tell me if the top cover of your current 3spd tranny has 4 bolts or 9. Also give me the casting number on the intake log of the head so we can see if they just replaced the head on the motor. That's a good and easy swap for better breathing on the earlier I6's.

For changed the 6cyl block bellhousing pattern in '66, then again in '81, right before they discontinued the motors (go figure?), so I need to know the specific casting number of the block to give you advice on the T-5 swap.

The T-5 is a great upgrade to the I6, but you will shread that 4cyl tranny behind the 302.

I have read several sources that said the 84-85 T5 would be shredded by the increased hp, but that there was an upgrade to the gears quality after 85 that should handle the hp of the 302.

I will check front vs rear steer. I have read that all production car models are rear steer.

I did plan on doing some fab with this approach.

I am guessing that the springs on the 87 Mustang are going to be to soft due to the small engine in the car. Any Idea about how stiff the Merc springs would be?

I would be interested in the 87' engine but it's just too far for me. Maybe next time. As for the T-5 behind a stock 302 might work but not for long if you drive it hard. The rear end change over can be done and even a rack/pinion steering but as far as using springs and other such things I wouldn't head the direction. If you do decide to go ahead and do it good luck.

The '87 rear will also have coils springs in the back..not sure on the Merc. Your Mustang has leaf springs. So, you'll have to deal with that.

As for the T-5, find out the number on the data plate, then compare it to this chart:

You'll learn how strong it is from that chart.

As far as the rest of the stuff..good luck and let us know how it goes. We'll help where we can. And again, with your current motor/trans info I requested, I can lay out the T-5 swap into the 6 easily for you.

Considering that I have been unable to locate a 302 t-5, what donor car(s) should I be looking for to find a 4 speed transmission?
