only a mustang owner would have a bagged minitruck and obsess over horse power, lol. fuggin rednecks! one thing i can promise is if you do swap the motor, any real hp and you will have the god awfullest wheel hop known to man, lolol! 4-link 5-link hell 6-link that biitch and still...wheel hop your ass off! bags cause that with trucks.
i swapped a 4.3 for a 330 hp 350 in my bagged s10 and DAAYUUUM! nothing got rid of the massive wheel hop.
