Yup....definitely!!! One of the problems I am having is that the engine bay harness is from a '95 F250; those trucks didn't have the airbag in the steering wheel...also the 300 six's power steering hi-pressure hose is too long and the 351's power steering pump isn't working.....
Well I finally got the proper engine bay harness put in...not only did my air bag sensors plug in but the wiper plugs in and works along with my stereo. That Y pipe I have is one for a '95 F250 with a 351 so it is different compared to the Y pipe for a 351 in an F150....anyway, I really love how different my truck drives with the 351 under the hood. My only quibble now is that when I had the 300, I swapped out the rear end from a 3.08 to a 3.55 which really made a big difference on take off. But now that I have the 351, it seems a lot easier to take off in second gear because first feels like a granny low gear. I'm toying with swapping my rear diff with an LSD anyway so should I go back to a 3.08??? What do you guys think???
That would take the "granny" out of first unless you want to lose the highway "overdrive". Find a happy medium like a 3.27, 3.28.
