My 422 smallblock build

I dying to know how it runs !
I sold my W2 M1 NOS dual plane but still have an NOS factory cast iron one . Which I would like to have ported and try to make a F.A.S.T class car .

I have searched the net for dyno results or even performance reviews of them to no avail …. Everyone that has run one stops short of describing how they ran .
