I have seen alot of thunderbirds that have done a 460/c-6 swap and used carb. I was looking at a 460 in a F-250 for an hour today going.....hmmmmmm. The twin throttle body with seperate intake tubes to the fenders,serp belt setup, cowl hood for the t-bird and even use the E4OD to make it a cruiser car. I know there is a guy that can reflash 5.0L computers to use with 460's but you have to use a Bauman trans controller for the E4OD. But I want to see if anyone has gone to the lengths of this kind of swap. Pisc too if you have them.
Thanks

Thatd be neat. With the FI and OD it would be a bit more streetable (gas wise) than carb and c6. Might see 18mpg instead of 12.
Then find room for a pair of holsets.
My dad's e250 throws no codes and averages about 13 mpg. I doubt there is anyway to get better mileage out of it without an engine swap. His old van had a carbed 460 and got 12 mpg. Other then a rebuild, I don't think it would be worth it to try to keep the FI. Just my .02
Take that e250 and drop about 2000lbs off it, 2/3rds of the frontal area, .20 off the drag coefficient, re-gear it for a lighter car, and you will probably pick up a few mpg. Theres more to gas mileage than the engine :P
you should be able to get decent mileage considering i know a guy with a 55 chevy that has a dual quad tunnel ram on a 454 and he gets 18 mpg.
Yeah but those burnouts I couldn't resist doing would just ruin all that.... :burnout:
Whatever happened to your big block Cougar?
C'mon guys, don't tempt me to do another super budget engine swap! lol
There ya go... A Bird with a 460 ain't going to be exactly frugal, but with the correct gearing, I suspect 18-20mpg would be possible running a steady 60-65 mph...
Now that said, I've seen a stock 460 in a trunk Stang that only ran 13.5s, my Bird will better that(of course I have prob $3000 in a 5.0)...
Well don't forget that if you get the 5.0L pcm set up to run a 460 SEFI instead of batch fire, you will get better milage. I met a guy on a Cobra kit car site that does that, reprogramming of pcm's to work with the 460's. I know that it is hard to fit that under the hood but a friend at work is doing a 84 Cougar with a single 88mm turbo 460 and it all fits under the hood. But he is running 3 fuel pumps and major tune on dyno's. Not really a street cruising kind of car.http://www.performance-shop.com/yabbse/index.php?topic=38741.0 Check it out.

MAKE him register here.... i wanna see pics of this thing, sounds sick!!!
Oh yeah. I guess you have to sign in. Sorry guys. Actually I talked with him at work today and it seems he is having a fuel issue. When he hits arround 4000 rpm the fuel pressure just drops off to 25 psi. He is running 3 pumps so now it is time to start digging and see where the problem lies.
Sounds like it's time to ditch that multiple fuel pump abortion and pick up an Aeromotive pump. For something like that, you're not going to be able to go very cheap for a reliable fuel system capable of what he needs.
Good luck,
Don
Well it seems the pump suck awesome. So awesome that the pickup was actually going against the bottom of the tank and causing a block. Fixed that with a little tpuppies and wow.... its fast.
I looked at this a few yaers ago. The FI 460 has what looks like a carbed intake with injector bungs added in. I was told that the intake only bolts to those FI heads and no aftermarket head can be supported, so if that is the case then stock is the only way to go. Use an Edelbrock intake elbow and adapt the 5.0 TB to the intake and viola all linkage and harness connecters are supported. If you can some how use a good set of heads the thing would be brutal. As far as the tranny. Stick with the AOD. JW ultabell and I think Lentech make a bell housing to use it behind the BBF. This swap would be simple, get decent milage and could haul ass if set up properly. Use a turbo and the heads don't matter......Food for thought.
AOD behind a 460? They can hold up to that?
Correct, the EFI heads and intake are not interchangable with carb'ed heads/intake. A decent set of worked 4bbl heads and a carb type intake with bungs welded in would make it a monster and wouldn't be crazy expensive.
If you know people, you could do it silly cheap.
-Don
Thats true. See I would just do it all up one year so the engine was in and running and the drivetrain was working right. then the following year do the engine mods. Yeah some Edelbrock heads,intake and tb adapter would work out awesome for that. All in time. Still having trouble finding a good 5.0L platform to start with.Not may up here in Canada.Lots of 3.8L
The 460 FI swap sounds great on paper, but unless you want to make more than 600 hp with a stock block, a 408 W would be a wiser choice.
Of course this is coming from a guy that has done 3 460 Fox swaps. (all carbed of course)
If you are wanting gas mileage, then the big block swap is a total waste.
When we did our first BB swap in 1995, the only way you could make power was with a 460. Now a 351w can make that power easily.
Just my .02c;)
Very good point you make...but who can resist MASSIVE quantities of torque EVERYWHERE?! lol
BTW, I saw a straight six fox fairmont in the local 'yard today...was very tempted to pull the engine and k-member for my dream of an EFI turbo-6...lol.
I'd be dangerous if I had money!
Gas milage is not a concern. I just don't like carbed engines. I play with fuel injection all day so it is just seems right to keep it fuel injected....plus I do not see many 460 efi anything unless it is in a truck,motorhome or cubevan. Don't need 600hp to have fun. The engine is all torque and thats what I want on the streets. I am not really into drag racing with it but the occasional foot to the floor to boil the shoes will be nessasary.
Yeah a 351w would be a good swap but the only thing is that I have to change everything to do a bigger small block swap, so then why not go bigger? I did this on a Capri. I went from 302 to 351 all efi. It was expensive as hell. The engine alone with all the swap parts was about $3500 canadian...that was when our dollar was . So is a 460 swap but again.......bigger and something to talk about.
I am trying to get my buddy on here but he is racing this weekend. I will try later.
I understand. As much as I try to convince myself to pull out the 460 in my 87 TC, (and put in a 302), the allure of a big block in a "late model" car pulls me back in.... lol :D
So, I can see where you are coming from.
Good luck on your project.
Hey. you have a 460 under that hood? What did you do to make it fit? Do you have a build up I can see?
Thanks.
I found a 87 turbocoupe auto for a starting point. I just need to sell my Bronco to pay for it.
i cant wait till i can start working on my 460.....................and i belive tbirdguy did his swaps before he was on this forum..
Yes, both the Gray Bird and the 87 TC have 460s in them.
here is a link to my photobucket account with more pics:

I have posted info on this forum on the cars. I just don't have all the links.
Awesome. I have to check it out at home. Work blocks me. I will also do a search on 460 swap or big block swap.
Sweet. I just picked up a 88 5.0L Thunderbird today. Really happy with it.
