Pedro The Swift, Clubagreenie, more than a few have done it

Cost 7k for trs to convert

ensure you trust the people doing the work,, dont rely on reputations.

yes there is a worthwhile difference in 600cc's,
better again with a proper 4.6 fuel map.

ensure the block is out of a 4.6 RR, (not 4L) the older the block the better. ensure whatever liners they use seal at the bottom.
use your heads, use ARP studs, use 4L pistons and rods to raise the compression, use MLS headgaskets, use Hylomar spray gasket, use 100lbs with 5 stages(the last is a repeat at 100lbs after the hylomar has set), use a new cam suitable to your application, use new valve springs, use a 88deg thermostat, use new hoses, use a Mark Adams flashed ECM(this will transform your motor), use whatever funds you have left to install sequential LPG,, use your new best friend at the servo to get great two for one deals, lastly use your last two dollars to buy a lucky rabbits foot.

Here's mine:

4.6 short block (new), 3.5 gas flowed heads with chev valve springs, standard valves, tin head gaskets, inlet manifold machined to match heads, Piper 270 cam, SS extractors into SS performance exhaust. BRC sequential gas system.

Thanks Fellas. Eevo I can get a 4.6 with T liners from TRS for way less than 7k. I will go this way & get the computer sorted as well.

AAAh I'll be fitting mine. Makes a big difference.
they have this: 1 x brand new 4.6 short motor, complete with cam and t/chain set. Only 1 left. $3,950.

I wouldnt want a new one,,
you have to pull the crank and pistons anyway to put Tophats in, my crappy low HP HC 4L still had hone marks,,
