Hey I'm rebuilding a 351 Windsor out of my 1978 bronco and need to know what cam I should use. It's a stock crank and rods with 9:1 pistons stock heads and aftermarket four barrel intake.

 

Do you have original engine? There was no 351w till the 1980s in Broncos. Only 351 Modifieds

 

It's a Windsor I don't know what it is out of it was in it when I bought the truck

 

Something like a 260h would do the trick, that would produce a nice wide powerband with better topend power than any stock motor and impressive lowend torque when combined with longtube headers.

 

Is this the one you are talking about?

Yes that is an option as is this dual energy grind which puts more lift and duration on the exhaust side to compensate for the notoriously poor flowing exhaust ports all SBF heads have... 35-416-3 - DUAL Energy? Hydraulic Flat Tappet Camshafts
Another thing I'd suggest is swapping out the stock smog heads for late model E7TE heads to gain 1/2 point of compression or go to GT40 heads and also gain 25-30% more airflow overall.
