hp #s for 351 and/or 302

Anybody know how much horsepower and torque these motors had stock? If not where can I find out? Also, what is a good transmission/x-case to go with it? I was thinking maybe t-18 and np205. How much would an adapter cost for a ford tranny to a dana 18? Thanks

It is a 70's 351. Is there are large difference in power between a windsor or a cleveland. When you say new 302, how new are you talking about?

Re: hp #s for 351 and/or 302

new as in 2000+....ive seen specs on 302s for as little as 140hp but 290hp for a 302 boss....without work the windsors were down on power because of there small ports..just cant breath properly but they are much lighter so power to weight came into play...the 302 boss is basically a 302w with 351c heads .... the windsor also revs much higher than a clevo....hen i find more specs i'll pass them on

The 96 and up 5.0 HO all have about 225hp. But they are very easily built to whatever HP you can afford.
You can easily get 300HP/340ftlbs with well chosen bolt on components, a good choice of cams, and port matching the heads. I had mine Dyno'd in Vegas at about 275hp at the rear wheels, but that was when I was running the E303 Cam. I have since swapped in a B303 cam which gives up a little HP for more torque and stronger power band in the lower RPM range. My engine came out of an 89 Lincoln Mark VII has about 89K miles on it, and nothing more than bolt on mods, and port matched stock heads.
My engine is very strong, it can easily idle in 3rd gear at 400 rpm under heavy load, then excelerate to 3000 rpm in about a 1/2 second without side stepping the clutch. It is about as good a rock crawling engine, as you could ask for.
