Steve Petty ( Pro Line )is as good as they come. That being said, there are others also. Steve Morris has recently moved on from Morris Racing Engines ( I've heard) to open a smaller shop to do engines that he is interested in. I personally would track Steve down and talk to him. his stuff always seems to make great power with reliability. Nelson competition (in FL ?) is a good choice too. I don't know anyone in TX, but I'm sure there are a few.
