351W in a bronco? I thought they came w/ big blocks.http://boston.craigslist.org/sob/pts/269400757.html. and will these heads/ intake fit on my 302 if so what kind of power upgrade will I see?

 

The later full-sized Broncos were available with either a 5.0 or 5.8. The 5.8 wasn't set up as a powerhouse, it was set up for torque production. In 96 (the last year of production) the horsepower was up to a whopping 210 with 328 ft/lbs of torque. Probably not worth the time.

 

I'm not looking for the whole thing I just want to use the block for a drag car. but you're sure it's a small block right?

 

Your original post asks "will these heads/ intake fit on my 302 if so what kind of power upgrade will I see?", but now it's just the block you want? But, yes, they came with 351 Windsor motors for years.

 

sorry I wasn't clear in the 1st post. I want the block for 1 car and was asking about the heads for my other

 

think the newer 351's have the same heads as a 302 ?
that is the reason they don't have much hp
you will need pre 74's to get the bigger valves on a 351 w
thinking they have the same valves as the gt 40's or if not very close
