5.0 to 5.4 swap

I started this project last year and I wish I didn't. I'd like to put the 302 back in it but I already cut off the brackets that hold the motor mounts on and not only was that a stupid move but I also threw them away and I'm sure they don't sell them anywhere or I'd weld them back on. What should I do now?
On the 5.4L, I had one in my '08 F-250. I know people like them, but it was the 2nd or 3rd worst feature of the truck in my opinion (worst was the ZF6 manual trans, but at least that was so bad that I could file a lemon-law claim and Ford bought the truck back from me). It made great power above 3000 rpm, but it couldn't get out of its own way below that. And the mileage wasn't bad, but not good enough to make me at all willing to live with the power band (average of 12.6 mpg in a crew cab short box, with 55 mph highway highs around 14 mpg). I could see it being a good engine in a hot rod, but especially considering the much bigger task to force it into an old Ford, I'd go with a 351. Or if you really want a "modern" engine, an LS (shudder!). Yes it's a Ch*vy, but that also means there's tons of aftermarket support for swapping it.

Well, you'll need a manifold, $400 or so. Carb, another $400. And, you will need a stand-alone controller for the ignition, $900 or so. Also, you will need a transmission controller $800 and up if you stay with an automatic trans.
Yeah, motor mounts are the least of your worries. Did you check out how your right valve cover and the heater box both need the same space?
Get a new set of SBF perches from the JY and then put a 351 in it. Save yourself a huge hassle, since if you're asking how to make motor perches, I can only guess you don't have the mad skills to deal with intensive conversion wiring and troubleshooting issues relating to making all these new controllers work together.
Sorry to sound critical but I hate to see another OBS truck go to the scrappers after a failed swap.

Yes, you have started an expensive project, only three things you can do. Forge ahead and don't forget to bring you checkbook. Anything can be done, but there will be obstacles.
Other option is to backtrack. Brackets can be found, check the junkyards. By the way, SBF refers to small block Ford.
Last option is abandon ship, but that also means a trip to the scrap heap for your truck.
Best of luck, it's your call.

Interesting thread over in the bullnose forum.
Very similar truck, but a very well thought out and likely heavily funded project.
