Hi
I have the 4.3 liter out of my blazer.
Next question, what parts will interchange with a 350/5.7 liter chevy.
I have a few new parts for 5.7. I have rings, bearings timing set.

Thanks
Steve

 

pretty much everything will work. all the sensors, all the front accessories. I think the only things that wont work are the obvious things like intake, heads, manifolds, etc.
