i have a 1991 RS(305). I plan on going to the strip at least every other weekend, so i am looking for around 400HP. so first off iwanna ditch the 305 and probably just go with a 350. any one know a combo of heads, intake, cam etc..that will put me at 400+HP.

 

also will my stock 2.73 rear end hold 400+HP? and if not is there any way to build it up with out puting in a 9" or 12 bolt?
