I'm planning on replacing my 302 FMX combo for a 400+ HP 460/c-6. I don't have the knowledge to build up my own engine so I decided to go with a crate motor. Do I have to upgrade the suspension since i'm more than doubling the horsepower I'm currently getting or can I just replace the tranny and engine and be done with it? I don't have pwer steering or power brakes, so should I look into upgrading anything in that department? Any help would be appreciated, thanks.
