ok I'm still new and can't seem to find what I am looking for when searching or even find threads about this.

I have read the threads How to do the 3.4 long block swap Boogie! and Dales 3.4 swap tech artical.

but I didn't see a clear answer on if you have to change any of the 2.8 wiring harness with the 3.4 harness?

if it was there I must of missed it, and sorry if this question hase been asked a million times.


Also can I bore a 3.4 and stroke it out? would I need bigger injectors or would the stock 3.4 ones work?

Thanks for any help.

If you reuse the stock manifold/sensors you don't need to change the wiring, you can bore it out (-this is a repair proceedure, not performance-) if needed, there's no stroker cranks out there for it but you could have it offset ground if you really want to and you won't need larger injectors.

On the smog stealth swap, you keep your factory harness.


I have done a system where you swap the harness and ecm. Not worth the effort on an already MPFI engine.
