You know Doug, If you want to think outside the square a bit the MEL has a few hidden tricks up its sleeve, like it shares the same bore centers as the 429/460 so with a bit of trickery you could fit the stroker cranks for those into it, Head bolt pattern is the same also, so by blocking off a couple off a couple of coolant passages in the block & a set of clever pistons, sheetmetal intake etc ...who knows what might be possible.
Oil gallerys in block are way too small & need the big drill treatment, definitely different, bell housing bolt pattern is same as FE so no problem for aftermart scattersheild etc.... how do I know all this, well a couple of years ago a guy wheeled one into my shop with a spun bearing & toasted conrod...being in NZ they were rarer than hens teeth, just happened to have a 429 in pieces at same time & 1+1 = 2 etc etc. Someone stuck one in a 57 T-Bird back in the 50's, be a cool ' what the hell is that thing to do with all the bits available now, just for the hell of it...
