Ok, I have been doing alot of reading and I really dont know that much about the mechanics of things. I have a 99 Grand Prix GT coupe. I also have a 92 Olds 88 Royale that has been trashed and crashed by the wife. I am thinking of pulling the motor out of the Olds and building it for the GP. How hard are cams to do and would can you also do the rockers too or do they somehow counter act eachother?
