Looking for some basic mods?

Here's an idea ? After tune up, maybe an 8 1/4 rearend 355's with trac lock ? Start from the back and work your way forward ? You do know what's going to happen when you ad a four barrel, cam, headers, and a shift kit to the transmission ! That 7 1/4 is going to be making not so funny noises.
Ask me how I know.....
