Not really a performance build up except comparing to the stock six banger, but a hemi swap anyway. At first ti seemed like there is no way itr would fit, but in the end the 5.7 out of a 2004 Durango and a 904 trans slipped in there just fine. Had to modify the engine mounts, oil pan/pick up and build new "exhaust manifolds". Solved the fuel iSSue by installing a half gallon auxilar tank in to the engine bay where the original in tank carburator pumps supply the fuel. After that is a MSD EFI pump + rgulator, and the return is to the auxilar tank. Seems to work fine. The wiring and computer came from Bouchillon performance as well as the 2003 "fly by wire gas pedal signal conversion box". Didn't expect much of the combo, but I must say that there truely has happened some progress in the 40 or so years, when the last predecessor was designed! Oh, and almost forgot; the power steering pump puked all the gaskets out of the stock rack & pinion, replaced it with a GM LT1 pump that has lower pressure. Needed new oil lines, drilling the mounting holes bigger and honing the stock pulleys hole bigger to fit the GM pump.
