E58 400 plus HP Dart sport build

So the freaking engine was supposed to be done by tomorrow am I doubt it ever will be. I call today and the brand new compcam double roller chain is to loose for his liking. At this point it blows up good riddance I'm done with this mess. Once it's running good chance this car leaves and I buy something else restomod with newer engine and running gear. Basically I looked at old chain and gears they were brand new. I knew someone had replaced and didnt set timing right on distributor and carb and then needed new tank they quit. I'm reusing I really don't care it's new and a double roller was stock as comp cam is junk I would not buy anything from the Edelbrock automotive alliance again. Hopefully tomorrow I get good news or it will sit at shop till I feel like going to get it
