Wondering if anyone has dropped a 5.4 in a 57(1/2 ton)? I've done a bit of searching, but haven't come up with anything. I am not sure of the bay size of the 57, but can easily find the dimensions of the 5.4 (It'd be a 32 valve). And if it will fit in properly with the stock straight axle. Probably going to go with a carbed motor and a 4r70w with a stand alone controller if everything will fit with not too much chopping. TIA
Some of us only understand CUBIC INCHES here, so give those of US that do a Break & Please explain in American Standard what engine you are writing about, so that we may understand what you are asking & possibly give some proper input.

Thank'ee kindly, nice to be able to undertand what is being discussed here.
Seen a fair amount of 302c.iers in the '57, not as nice as a Built 223c.ier or a 300c.i.er, but to each his own.
The 5.4 is approx 330 ci, the newer modular family. Actually, the 4.6 is about 1/2" wider than the 460, even though it is only 281 ci, and the 5.4 is slightly wider than that due to the extra deck height.
well i was gogn to try and post a picture of a comparsion of a 4.6 and a 302 if you send or post your email I will send it to you. (oh leave out the @ and just use at and dot for .)

Don't worry too much about liters vs. cubic inches - there will always be someone around to translate as necessary.
The engine bay is wide enough you could probably put 1/2 an Allison aircraft engine in there. Plenty wide enough for cammers and hemis. Unless it has a very deep sump it should clear the suspension. The only time that becomes an issue is when converting to IFS.
I won't be slapping it in for quite some time ($$$ and other $$$ projects first) but just wanted to get an idea. I know 460's fit, but have never seen one in before (mine's just a 223-6) so I didn't know quite how much room there was side to side, although with the 223, I could put a chair next to the block and sit on it while changing the oil in the bay The motor above, yes has quite a tall intake, and hood trimming might be necessary (I'm alright with that) depending on how far I could get in down in there. I'm leaning towards this route because I know a LOT more about the mod motors than an older pushrod, and a carbed mod motor isn't something you see every day (well, at least not around here).
Thanks for offering the pic, but I have some of those somewheres. If I can find it, I will show a pic of a 4.6 and a 460 sitting next to each other...amazing

There's also a ton of height as well, if it fits under a passenger car hood it certainly would fit in your truck. Why would you want to carb a EFI engine tho?
"...uses a high energy spark discharge system controlled by a simple 12 volt module, coil pack and magnetic crank trigger that distributes a high energy spark to the appropriate cylinders. Initial timing is achieved by crankshaft sensor position and adjustable timing curve preset before the engines are shipped to the customer."
-From the above site.
That is how the mod is carbed.
Reasons...it's different, no wiring to an eec cutting and splicing from a donor car, etc. This is pretty much drop in, hook it to a battery and go.
FoMoCo and aftermarket make stand alone wiring harnesses that includes a small engine management module about the size of a pack of cigarettes that can mount right on the engine for the EFI engines in hot rods No splicing or adapting a production computer. Changing them back to carbs is a major step backwards IMHO. Might as well use a carbed engine to start with. Kinda like swapping a Y block into a 05 truck.
