Welcome to the Bolt,Mike. Not sure about the engine but a 4.3 I think is a good one. Since this is the Welcome Centre you need to ask that question in the General Truck Forum, or maybe since its "engine specific" try the engine forum.
Good luck with the project. Keep us posted and how about a pic when you can.

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
