Similar situation with my Suburban
Looked at that GM 502 crate engine and decided to rebuild the 7.4L
Passing CA smog a must and no one have an acceptable answer on the 502
So my 7.4L is looking to have a 280 cam, roller rockers, 9.x compression, worked head, marched injectors, etc to be a bit under 500 ft/lbs around 2-2.5 KRPMs, etc
Built 4L80E rated 1KHP
Gearvenders with the splitter option, 0.5 OD, which will turn the 4 speed into an 8 speed
5.38 diffs, but having a tough time finding it for the front
That will give a lower 1st and higher OD
Don't know if the Xfrcase will need beefing up
1996 K3500 Sub and fits/suits me
Either LT255/85R16 or LT285/75R16 on current 10" wide alloys. Not going to lift...maybe a torsion bar crank
Still deciding...
