Blew a head gasket :(
I went muddin and leaned on the old truck a little too hard I guess. I have a couple of choices and that causes a couple of questions.
1. Should I just swap the heads and run it till it dies? I've got a set of E7's on the motor listed below.
2. I have a 306 with ported and polished E7 mustang heads and a stock mustang HO cam with 1.7 rockers. This would be the easiest thing to do in my opinion I think.
3. I've also got a 408, but I'm hesitant to swap it into the truck for fear of breaking everything else.
If I swap in the 306 what do I do about the firing order? The mustang firing order is different and I'm not too versed in F150 computers.
Oh yeah....its a 93 f150, 5.0, E4OD.
Thanks for the input.

I'd got 408. Your E4OD will last until you mash the gas. That is if your U-joints hold.
The HO is just the 351w firing order if I remember. Just a matter of re-pinning the harness I believe. Someone will chime on shortly with a more definite answer.

The E4OD will last....I'd recommend a shift kit though...Too soft of shifts...Same as riding the clutch in a manual....

But you have to install a floor shifter for the E4OD if you mud alot. Gate shifter will make sure it stays in the gear you want even through all the bumps.I forgot about how picky the E4OD is tho, so a built 408 may not be a good choice. Honestly for a mud truck, you need to think about a 351w, something with torque. I wouldn't even waste my time putting another 302 in when a 351 swap is so easy.

Throw in the 408 and a shift kit. The E4OD was used behind 460's and Diesels as well, so it's durable so long as the fluid is changed regularly, trans temp doesn't skyrocket and you firm up the shifts/reduce shift times. If you plan on mudding it frequently, I'd convert the rear to a 10.25 and the front to a D60.
How hot did you get the engine? If you didn't hit meltdown level you can replace the blown headgasket along with the other top end gaskets for not much money, just time. A little coolant won't hurt the engine so long as you aren't driving around everywhere everyday with it leaking.

#1 and 2 are you only real options, the 408 simply won't run on the stock EFI system and putting anything else in there including a carb is vastly complicated by that E4OD, and yes... if you did somehow get it running it'll break everything else behind it in short order. Engine firing order doesn't matter with SD EFI, the injectors are fired in batches and those batches are the same with both truck motors(5.0 and 5.8), so there is no rewiring needed to run the 306.

I've pretty much already decided on the 306 for simplicity sake. Its a direct bolt in and I'll throw a set of headers on it while I've got it apart. With the 306 in the truck I can always throw a little shot of nitrous on it for the torque I may need
.Putting the 408 in there was pretty much a pipe dream due to all the mods I would have to make to get it to run. I threw around the idea of converting it to mass air and modifying the hell out of the truck but at the end of the day its pretty much a daily driver/weekend play toy.
