can I switch my 1996 k1500 305 motor and tranny for a 350
I bought a 96 k1500 4x4 with a bad tranny and now the head gasket went, I don't feel like repairing it has 230000 but I cant find a decent 305. I found a 97 with a rotted frame but motor and tranny have 127000. I wanted to know if I do change over will I need to change the harness and the computer
To make sure everything will work you will have to do that.
It's all the same. If it's a 350 go ahead and take the computer so it's programmed for one.
All Chevy bolt patterns are the same. Different engines & transmitions bolt togeather, & most use the same motor mounts too. Use everything that goes with 97' engine too. 350 for a 305 is a good choice.
5.0 and 5.7 used the same ECM The 5.0 pcm will not lean out the 5.7 engine at all. the 02 sensors will correct the fuel mixture and you will not have any trouble with running what you have already. The only reasone you would need to make any mods to the pcm or the wire harnss would be if you where going from a 4.3 to a 5.7.
Your telling me a pcm programmed to an engine flowing 305 ci worth of displacement that uses a MAF sensor isn't going to tell a difference in another 45 ci of displacement? The maf reading alone will be different, the fuel trim tables will be too lean. It will run, no doubt about that but it won't be right.
yep. gm says there both in the same parametersFYI... several GM trucks use the same 16197427 ECM for 5.0 and 5.7 just change out the chip if you want..

Can I put a 1995 Tahoe motor in my 1990chevy k1500?
Is the wiring harness the?
Yes, as long as they are the same engine size you'll be good. Going v6 to v8 would be alittle more involved. And switching from a 305 to 350 will be plug and play but I would advise the appropriate pcm to go with the motor
