I was wondering if anyone could shed some light on this for me. I was wondering if a 69 crank will fit in a 91 block. From what I've came up with they're both the same 3.5 stroke and the rod length is the same along witht the fireing order. I was also wondering if you can run a 3.75 crank with everything else "stock?" I was hoping someone with some experiance could slap me a good one on this. Thanks!!!
Get out your manuals BroncoBill! HEHEHE
Well Bidi, since you slapped me in the face w/your glove I just had to start looking this $hit up. First off, my *good* manuals only cover the 78/79 Bronco's which were of course the best one's God ever gave us. *Unfortunately* they only came w/the 351M/400. Basically the same damn engine Except for the crank but that really doesn't mean $hit for what you want to know. By the way, just as a bit of trivia the "M" in 351M does NOT stand for "modified" as so many poor souls believe, it stands for "Milford" as in the Milford assembly plant, just as the Clevelands & Windsors were named after THEIR assembly plants, so was the Milford.
Anyways.
The 69' Windsors were the highest rated HP that Ford ever produced (290hp @ 5800rpm) but you should be able to use the crank. The dipstick changed over the years moving from the timing chain cover down to the oil pan but that shouldn't matter to ya. The firing order isn't as critical as the stroke & journal sizes. The rod & main's are the same size so you should be good to go unless the crank has been turned somewhere along the line & then you really just need to mic it to know what bearings to use.
So There.
