V8 swap
I have a 2001 Blazer with the 4.3l. The engine has a knock, so I was considering an upgrade to a V8, maybe a 5.3l or 5.7l.
questions: 1. will a V8 fit without major modifications. 2. will the wiring match up or can I get a harness that will make everything work like original. 3. would I need the computer from the V8 donor vehicle. 4. would I need to upgrade tranny or transfer case. any input will be greatly appreciated and useful. Also, if there is already a thread about this, I appologize, but I couldn't find one, thanks. |

I'm thinking the same. But i've checked all over JTR and can't find anything about 5.3s...
