I know where Rowlett is, I have a co-worker that lives there. Im out there every once in a while. Post some pics of the car, we'd all love to see it. I dont know if you have an engine builder but Kim Barr, builds race engines and is really good from what I hear, hes out your way. Hes a bit pricey but you should get what you pay for.
My 460 is a d3v3 block, C9 rods, and some other wierd ods and ends, Its been .030 over already and one cylinder is sleeved, other than that shes good to go.
