Running a Arruzza Stage 5 intake with a pair of his modified 650 Carters on the 572 that I am working on.This thing is a torque monster!You should think of calling John Arruzza,he was right when he told me how this motor would respond to his setup.If you call him be patient he is very hard to get a hold of. Good Luck Sam by the way nice body and paint what shop did the work?
