Nice.....I am building somthing very similar, and I hope mine runs as well as yours. You don't even seem to have the blower lope most do...Very smooth driving....

Mine is also 446 cubes, but with an OEM block and I will be ordering the 8-71 soon from TBS. It was built by a friend of mine that ran it on E85 with an 8-71....How did you come to using two 1250 Dominators? I have a pair of 750's I am going to try. And no boost refrencing?
