The 4.3 is a great engine. I have run them to well in excess of 200k miles.
Be careful putting a Chevy engine table in your house. It will increase the property taxes to the point you may not be able to pay them.
As soon as its done it will be up for sale. It's chevy.. why keep it.. The 4.3 is going in a jeep so i no longer have carb problems when i get into the mountains..
Around here it's Mopar or no car..
