For many years I have wanted to get a motor from DSS so a few months ago I really did some research on them and a few other builders and I found a lot of people that do not have good things to say about DSS. I mean this is usual for any type of business but they really had some people that were critical of them.
Fortunatley I found a local builder (Fulco) that has a reputation and list of credintals that would make a NASCAR team drool.
I would take the Ford Racing motor over the DSS unit at this time. Ford has a great reputation with their crate motors.
Just my .02....
