Ok, my friend has a 98 mustang gt 4.6 with a 5 speed, if i put a stock 350 in my car, i have a b&m megashifter and im going to get 373 gears...........could i beat him, because hes one of those kids that thinks his sh#@ doesnt stink and i really would like to show him up

 

Depends on which "stock" 350. They came in various blends from very mild 2-barrel engines in the 70s that put out less than 200 HP (you'd get killed) to kick-butt monsters like the ZZ355 that put out over 350 (you'd own him). Do you have details. Is it an LT1? or an older carubrated 350? A new crate motor (if so, which one)?
