So, if an automatic ends up falling into my lap, make sure that it's a Mustang unit and maybe a 5.0 engine, rather than a Turbo 350 or GM 200R4 attached to a 4.3 V6, right?

Thanks!

Would you happen to know what the final drive/over drive gearing is for the more common automatic transmissions? It would help out for sure ! ! ! Maybe post a link to a web page, or . . . ?

Tom, the info I posted took less than 10 keystrokes on the google search engine. Why don't you try it?

Good advice. Just SO many options you know? I'll take a poke around for sure ! !

Wish that I wasn't so "all over the place" with this decision, you know? Either things were easier when I was younger or I was just more of a hack and didn't care as much. Gotta check into that . . .

The most painless (and a good performing setup) is the 700r4 on a 2.8, 3.1, or 3.4 v6. If you're using computer controlled fueling (EFI) then you can choose whether to use a computer controlled transmission or a 700r4 (both came with those series motors, depending on year). The computer controlled trannys are pretty specific for year of ECU, and the electronic controlled units underwent changes from year to year during the 90's so the 700r4 route is a little more likely to have less repair/replacement compications in the long run.

Oh, and here's an oddball. The 84-86 Jeep with an AMC 2.5L 4 (NOT the Iron Duke version) used a Chrysler 904 Torqueflite 3 speed automatic with the GM 60 Degree bolt pattern. Starter is on the passengers side....

Hey Greg, I used to have one bolted up to a 85 Cherokee 2.8 V6 also. Bulletproof behind the V6 but only 3 speed.

I use a 3.1 with the 700R4. It has a .7 overdrive and with the stock 3.9 rear I was turning just under 3000 at 80. I run 205/75/14 tires.
Now I have a 3.25 gear and 80 comes up at 2300. Really nice on the open road.
I drive a lot and would not trade the auto for a stick.
I have a manual lock up on mine so Ican lock or unlock the torque converter when I want. It just suits me better than the B&M lock up I tried.
My trans had over 90000 on it when I installed it and had to rebuild it after an additonal 75000 miles. It came out with out removing the engine.
The engine now has over 180000 on it and is running fine.

Steve has very good points.

The best way to fin out what you need is to know what you have.

Knowing the gear ratios of each trans is a must. Need to know also the tire dia. Now you can run the numbers a figure out what you need at the require rpm, mph etc.

If you send me an e-mail at bg.gtv6@verizon.net I will send you the X file and you can just plug the numbers and will give the speed with the chosen gear ratios.

You will know to know the trans gear ratios, tire dia, rpm.

Any other way you are only going to get what may be the right thing and you will never be sure.

It is our attitude that will determine the outcome

Hi Robert,
I am trying to do what you did. I set the engine in today and wow it looks like this will be a piece of work, not fun. With the front pulley sitting on the steering rack and the transmission sitting on the MGB cross member there is hardly enough room for the carburetor. I didn't want to bubble the hood. I didn't want to use F.I. I have a stock manifold and carburetor from a S-10. I have cut into the foot wells on both sides to get the engine and transmission back far enough. The right valve cover is almost touching the firewall. The engine will probably have to come up an inch to clear the steering rack. If you have any advice or suggestions I'd like to hear from you. You can contact me off list at bobtcars@wildblue.net.
Thanks, Bob Tarpenning.

My engines are situated so the front pully is behind the steering rack, and the drivers'side bank is near but not touching the corne at the firewall. This occurs with 2.8, 3.1, and 3.4v6 motora all the same. I do use a slightly different motor mount to slightly lower the motor, but to me it sounds like the motor is not back far enough. This usually occurrs because the top of the transmission interferes with the top of the tunnel, approximately directly below where the front edge of the radio is located.
Got any pix of the motor in place?

In reply to a post by TeamEvil "why you want so much 'fire' in a street machine."

Tiny appendage . . . obviously.
TC

Seriously TC?
Seems you have totally the wrong idea, not everything in life has to do with your... appendage.

Quite simply, there are some of us who enjoy the thrill of extreme acceleration. And what better way to provide that thrill ride on a regular basis than a big engine in a small car?

Would you say that someone who loves to ride roller coasters has a tiny appendage? That'll get you banned at Disney World.

So there you go.

And for the record just because you care, couldn't be farther off the mark.

Seriously, get a V8.

Jim, I think he was making a joke at his own expense, the "why you want so much 'fire' in a street machine." was quoted out of the post above his from Scot.

Many times MGB enthusiast whoi want a bit more power ask for specific advice. That is the case in this thread.

He is not asking how he can get 1000 hp that is not his point.

But many have to push and push what they like to others who are not interested in 1000 +hp
The question is, so why even mention something they do not want.

It seems to me that it would save lots of time and writing.

I love force induction, but I am not pushing to anyone who does not ask about force induction.

I am beginning to think that it should be two other sections in this forum, Fuel injection and mega hp. thumbs up smiley

I also do like hp but then I go to the Vette or Cobra forum for real power.

What you say is true enough Bill, but at the same time it's just as fair to ask, why must certain V6 enthusiast insist on proclaiming the V6 engine as the do-all, be-all and end-all in engine swaps even when the person has expressly said that he wants to do a Rover conversion, or even a very specific Rover conversion? It seems to me that the knife cuts both ways.

The only fair way to handle this it seems to me, is to provide all the relevant information about all of the common swaps (and some of the not so common ones) on an equal basis so that the owner can see the real pro's and con's of each conversion choice and make an informed decision based on his own circumstances, car, resources and abilities.

I am quite certain that had I been advised to do one swap when another which suited my needs better was known I would be resentful. We should scrupulously avoid this.

And just so you know, I've been told that this site is a V6 only site. I could be wrong but I really don't think that is the impression the frequent visitors here want to create.

Jim, V6 is an option and is not the only engine in this forum. Do not create something that is not.

No one has proclaim the V6 is a do it all, but hey it sounds good.

Many come to ask questions or to clarified their doubts in either engine V6 or V8 and occasional a 4I to get some technical advice or to share their success. I enjoy those who accomplish their swap either V6,V8, 4I and some 6I. It is great to read their post.

That is all. Take it anyway you wish Jim. Not trying to create a situation here, I know you know what I mean.

Jim,
My opinions are just that: mine. Yours are different. It is too bad if your feelings are hurt. It is not my intention to direct any disrespect towards you or your choices when I voice my opinions.

One opinion of mine is that some people come here to figure out what (if any) conversion route to take, and they ask questions to try to figure it out. As part of the learning process, many of the questions they ask are not well posed, and the answers they get to such questions might not serve them well, based on their true intent and the scope of the answer. It also happens that 'good' answers come nd go as times change.
I am sure some of the answers and comments here are colored by my 'old fashioned' values (economy, responsibility, etc.) but the intent of mine is to provide information that is not misleading so that people take advantage of my learnings as they are exploring the paths they really want to take.

Bill and Scot, believe it or not I am not singling you guys out. Bill, your business is predominantly V6 based and I think everyone understands that and you are not expected to act against your own business interests. Scot, your biases are pretty well known by now. But what irks me is the constant promoting of the V6 over everything else. Back when the majority of this forum's participants sneered at V6's I defended them and now that the shoe is on the other foot I'm defending the other engine choices. I also have my preferences but they are MY preferences and that doesn't make them right for everyone else, any more than Scot's preferences do.

So I'll say it again. I originally put a 215 in my car. I now know that the Buick 300 would have been the ideal choice. Had I started with that engine in all probability I would have avoided years of trying to get more out of the 215, blowing up engines, and on and on. If I became aware that the person who advised me to put a 215 in the car had known that the 300 was a suitable or even just an acceptable engine choice and had not told me, while advising me to go with the 215 I would resent that. I might resent it highly. The same thing goes if it had been the V6 or any other common engine choice. So what I'm saying is this:

Quit trying to make the engine choice for people who you don't even know. It isn't your responsibility, it is theirs. Just give them the best info you have and cut them loose. If they pick your favorite engine then all is well, you have a friend (and possibly a customer)for life. If they choose differently you have done them a service that they will not forget, and they will hold you in high regard.

Jim, slow down. You have changed the topic. I said,

"Many come to ask questions or to clarified their doubts in either engine V6 or V8 and occasional a 4I to get some technical advice or to share their success. I enjoy those who accomplish their swap either V6,V8, 4I and some 6I. It is great to read their post."

I agree that some do push other things and that is the point here Jim. Some like tons of HP others like something practical and even an old school (carb) daily driver. Others push and tell them what they do not want and some never comeback to the forum.

If a person on this forum would asked; I want 550 hp out of my 215 ci Buick. Well... then after some bla bla he would get a response with get a 455 ci Buick bla bla.

If another person asked, I want a 215 for a daily driver, he should not get the bla bla put a 455 ci I got 1000 hp

It takes away from his ideas and wants.

That is all Jim. No personal attacks to you or anyone, just making a point

It is our attitude that will determine the outcome
