You will need the 454 throttle body and adapter. And a different chip but that should all.
The big block should have sufficient fan/radiator clearance if the engine is still in the original 4wd position even with a long water pump.A stock 2wd fan shroud should work.
You will want a 454 size throttle body if you want any performance at all.

Ditch mechanical fan and go with wind stars and use the space up front instead of changing it behind
The only other option is to go short water pump and slide the engine back around a 1.5".Engine was moved forward ~3.5" to give me more rear driveshaft length (due to the doubler). Probably need to move it back and figure out driveshaft issues another way. Unfortunately, it seems the magnum box may not be much shorter than a doubler, but I haven't got firm dimensions yet.

Close call!
Was it a carbide bit for the port matching? I use those occasionally.. and the type and sharpness of the debris they generate is scary. Super sharp and they stick everywhere. Even with good goggles that kind of work always makes me nervous...

That's scary stuff. Geez.
It's scary (and stupid) how many of us have had that same issue. I had it happen to me a couple of times. First with safety glasses, then upgraded to goggles, then better goggles, then goggles with the lower vents taped up.Small update:
Doing some grinding on the intake runners to match the gaskets and a metal sliver came down behind my safety glasses and embedded itself in my cornea somehow. Back home now at 12:45am after 4 hours in the ER (actual procedure to remove it took ~2 minutes.
Just a warning if someone else actually has something like that in your eye (not just floating around on top)... go get it removed ASAP. If you don't, infection of blindness is a real possibility. I waited 5 hours before going and a rust ring had formed around it which means I have to get that removed as well tomorrow with a very small dremel.
Oh and WEAR GOGGLES when grinding little bits of metal!

I went to my optometrist too.
I never seem to notice until I try to go to sleep late at night. I found one with a late night call number. He came in to fix me up at like 12:30am once.I would have done that but all my injuries seem to happen on an evening weekend.
