I am getting ready to put a carborated 351 ho in my bronco, I would like to know what my horsepower & torque will be compared to my old 300 I6, and If anyone knows where a website is that lists horsepower and torque ratings for engines then it would be much appreciated thanks

i guess it doesn't appear to be working so the 351 ho had 210hp and 305 tq. the 1986 6's had 120 hp and 251tq.

 

Try this address:

THe vin for the van I got my 351w out of, indicated it was an HO engine.

How can I tell if it really is an HO engine or not?

 

I was also wondering what the red line will be? And will headers off of a 302 fit the 351?

 

if you want to know your HP and torque, a dyno is your best bet, if you do a little research, you'll find there are several variables in just the valves, HO motors might just be a 4 barrel vs 2 barrel, but some had different valves depending on car or truck...

I saw an article on GT40 heads, and these new GT40p heads that come on the explorer and mountaineer, the high performance crowd is drroling because these stock heads are performing better than some of the after-market heads...

so if you don't know the history of a motor, and the parts are a mystery, you really can't tell

 

yes on the headers.
