any tbi teen would work up to 92
not sure when the tbi started on trucks but any roller cam teen would work
any sb will fit but the tbi not work with an older flat tappet cam
any from a car thats tbi will work just needs the oil pan and pick up and hardware from the truck engine
if ya can any flat tappet cam teen that has the roller block that will work with the cam in the bad engine swapped over
I got a 88 4-v 360 headed 318 that was a flat tap cam...but a roller block...I swapped in some 1990 roller lifters and hardware on a lunati voodoo roller cam...used all stock valve train from the 90 teen
oh! and watch the early pre-magnum rollers...not all have the oil threw lifters...that 90 will have hollow push rods and oiling lifters and oil the old LA style shaft rockers
at least the 90 I tore down was oiling both ways...they were getting ready for the magnum engines
a magnum engine would work also,they are the same all but the heads and intake...pop his heads on the mag and bolt and play
good luck!
