The 350ho I see is 4.5k. and you'd still need an intake, along with all the other garbage that won't fit. Not sure if accessories all bolt up the same. Water pump among other things. It just keeps going.
For 4.5k you should be able to find a running 454 within about 1000 miles and still come out ahead.
