I need part numbers for an 427 FE appliation .I see lots of Chevey stuff.When going through several brands I saw one.it was ment for 460 that could be used if I had the spacer cut 1/2".Tuning , how likely am I to do that in car in my little garageIs the tuning nessessary? I want one out of the box.And pulley sets that fit and don't require trips to welder and machinist.Is life a struggle for everyone?
What does ATI's #916581( adapter) look like and how much will all this cost?
Any body put all this together?Is the Dove colant pump I allready have OK?
