Replaced both batteries and the starter today, turns out one of my batteries had 2 cranking amps, the other had 400/880. Starts like a champ now.
Time for a new motor.
Can't decide what to do.
Option 1
Buy a $1200 long block and reassemble the tins and intake.
Option 2
Junkyard efi 460
Option 3
Have a 460 built.
I'm really leaning towards rebuilding the 400. I already have all of the accessories that will work for it, however, they aren't the best motors in the world and the power will be the least out of the three options. If I go this route I'll get rid of the nylon timing gear and put a bigger cam in it.
After seeing all the **** that carl's been through with the factory speed density efi, I really don't want to go that route. At the end of the day, i'm still using a jy motor that's probably been through some **** with 20 year old sensors and wiring harness.
Building a 460 would be sweet, but without a core, and having to buy tins, motor mounts and a intake, It'll be the most expensive option.
Options 1 and 3 will be getting aftermarket throttle body efi.

You should do option one. You won't want to wire anything EFI and you have a huge hard on for the modified motors.
The best choice though would be to keep your bronco together and freshen up a 460 with factory efi, put a cam, straight up timing set and shorty headers and put that into your bronco once you have the motor rebuilt. Go to a junkyard on a half off day and stuff as much of the wiring harness as you can in the pan before you take it up front. It will bolt up to your transmission, and you don't have to do any fab work, just bolt in some new motor mounts. There's nothing wrong with speed density, it works. That's why you see all the old mexican workers driving old Ford trucks.

Hi, I'm Karl, with a "K". **** that guy Carl.
There was something bad wrong with my speed density 302, I'll give you that, but my junk yard roller motor 351 that was speed density ran like a scalded ass ape. Frick has told mehis350 tbi didn't have the ass that 351 did. On several runs people came up to me and said, "Man your big block sure does put some power out"
My advice, and it's just my advice, **** the 460' it's heavy, you have a doubler, you are making a crawler, not a mud bogger. The only legit reason for a big block in the Offroad world is a mud bogger.
Find a good running f150 or f250 with a 351 (**** a 302), part the truck out, keep the motor/trans. Trim the harness. Rock out with your cock out.
The acc. You are trying to save are an alternator (150 tops) and a power steering pump (150 tops).
Above all else, do not try to adapt fuel injection to a carb 460, that is just dumb for a rock crawler.
Again, my opinion.

I kinda support the 351 idea, but it cost more to make the power a 460 would and I don't think tommy would be happy.
IIRC the 460 is only a couple hundred pounds more than a 400, and I don't really see this as a dedicated "rock crawler."
Find a running fuel injected 460. Then swap into your truck and run it until you can build a new badass 460. After which you will have a 79 bronco that kind of fits down trails, makes lots of hp and noise, and you will be able to show off anywhere from Alto to Clayton... Until you have a catastrophic break down ( which we all know is another form of showing off ).

He has a doubler, if he wants to crawl he does not need displacement. If you want to mud bug go get a big block

I never caught why you are throwing out your old motor. Blow it up? Anywho, I would rebuild the 400 that is in it and put a big cam and high flowing heads, or if it has already had that done to it take the next step and stroke it.
