You probably could, but his has to be at least a 3/4 ton Suburban to have the 454. It would take a ton of work and fabrication including things like fabricating motor mount, an adapter for the transmission (possibly), and you would have to change the computers as well since you are going from a V8 to a V6. It would take a lot of time and money, but I am sure it can be done.
Hope this helps. Good luck!

95 chevy s10 with a vortec v6. has a mis


The Vortec 4.3 liter V6 is notorious for problems with the fuel injector.One injector solenoid feeds all 6 injector nozzles,and sometimes one whole side of the engine will not get any fuel.See if you can smooth out the engine by spraying some starting fluid into the throttle body(remove the rubber hose from the throttle body).If this doesn't seem to make a difference,you may just be dealing with an ignition problem(cap/rotor/wires/carbon tracks on the spark plug insulators).

Trans I.D. by vin code


I can tell you what engine is suppose to be in it by the VIN. I can tell you what transmission you have if you can describe the shape of the bottom pan. As far as the engine that you have that is tough. The engine size should be stamped on the rear of the engine near the distributor near where the engine and transmission meet. Rectangular pan 4 speed= 700r4 Pan like the state of Illinois, 3 speed= TH400 Squared off in front, tapers on both sides to the rear and slopes up to the rear, 4 speed=4L80E These are the only transmissions that were factory installed in a 1992 C1500. If it looks different let me know. You never know what someone has installed.
