Can I upgrade my 305 V8 in my 1993 GMC K1500 with a 454 V8?

Asked by May 17, 2017 at 09:43 PM about the 1993 GMC Sierra 1500 K1500 SLE 4WD Standard Cab SB

Question type: Car Customization

I'm wishing to upgrade my engine for towing and hauling capabilities and wondering if a 454 will fit my 1993 K1500? I know I will have to replace and match the trans, electrical, and computer junk but just wanting to know if possible or not? I know I can do a 350 swap but I'd prefer the absolute performance of the 454 if can be done.
