No Prob I figured after I wrote it thats probably what was up.
As to what john is working on he sells a complete welduo 930 setup. I can't quote retail as I don't know what he charges but wholesale is very reasonable and comes with and oil drain tank(that i won't be using) and everything is 321 and 347. here is pic completed on a 930
here is auto sports pic.
I should say also the 304 worked for me and for Jbrinkley and darkmoon, along with Phils(don't remember his screen name) for low boost applications I just decided I want to try this other version out as well. Probably better but if you already have the standard ssi you will be fine .. We did make all of our piping after the standard ssis out of 321
