I have am in the process of a Olds 455 installation..There are a few things that need to be worked out, but they are all relatively easy and doable...I currently have my 455 installed in the car..I am running the factory HVAC box, and the shaker hoods fits exactly right..
I have pics of my process and can advise about the process..I have dealt with all the processes that people have said werent worth the trouble...Anyway, If you would like to see some pics my email Address is

I would be happy to give any advise and pics of what the process was....
