I run a STS D21B and other then a little temperamental to break in it has been a very good engine. It really came alive and settled down after about a gallon, which I have found, is true with most big blocks. I am running it in a Hyper 8 but so far do to the local track closing down only got to race it once. I will now be going to other tracks around Georgia when the season starts back up. So fare I have not had any problem with it and do have a couple of gallons run through it with out any problem. I am only running 20% O’Donnell Race Blend at the moment and just took a head shim out. I broke it in with a HOT McCoy plug and I am not running a RB medium.
