So after working this truck for 20 years off and on I finally finished it. I did all the work myself but did but turnkey 347 Blueprint engine and new c4 tranny. Now the sad part I insured it 2 days ago and went to take it for its first drive to the store 2 miles..... made it 1 mile. Then white smoke out the left exhaust and instantly truck stalled, towed it home pulled spark plugs. Pictures tell the rest motor has 1 mile on it.
