Help! My 91 F-150 has 110k miles and the engine is starting to leak oil around the transmission. I am trying to determine if I should simply repair the leak, get a rebuilt 302, or upgrade to a 351. I really could use the extra power to tow my trailer over the hills around here, but I have two basic questions for the experts here...
1) Can I drop a 351 in my truck?
2) Would I need a bigger transmission?

Thanks in advance!

 

I'm doing the same with an 87 F150. I decided to
stay with the 302 as I will not be doing any real
hard hauling. Check thru the pages (all 100 +) on this
forum and you will see that this problem has been addressed many times with much good information being passed
along.

Wish you luck on your swap.

Thanks...I tried searching first, but the server said it was overloaded. I will keep trying!
