Have a real good look at that B motor. Most of the came out those truck you are playing
with and run real hard. They end up with cracks in the exaust seats and in the deck.
Plus you have to look for freeze cracks like you would with any of them.
All in I have two buildable B blocks I could have used, but after looking at the B motors and the Burtz Block kit I went with Burtz. Get the Block kit, the cam and the flywheel.
