Hey everyone, hoping for some advice. Had the engine blow on my 1996 GMC 1500 4x4 that had a 305. I'm thinking about replacing with a 350, wondering about any changes (i.e. computer) that may need to be made and whether you think it is worthwhile. Thanks for the help!

As long as you’re staying with the same year(s) of cylinder heads and block design they will interchange without any trouble. You may need to have the computer reflashed (reprogrammed) with a VIN number from a sister truck with a 350 that’s so the timing curves and fuel delivery will match the 350’s needs.
As for the difference between a 305 and the 350, (in my opinion) is that you’ll gain a bit of bottom end torque and possibly loose a bit of fuel mileage. So if you were planing on pulling a trailer with the truck, that would be the only benefit that I can think of for going with the 350.
