A np241 will fit a 4l80 and be pass side drop...can be found in 91 burbs I know
Really no need for a engine crossmember...you can use adapter plates and it'll bolt right into the small block mounts..can do the same with the trans crossmember if you get the right one...
On the fuel ,I use vett style filter reg and a walbro 255 inline pump
